TL;DR.Kwiminyaka eli-10 yokusebenza, iintambo zentsimbi engagqwaliyo zihlala ziphumelela kwiindleko zobunini kwiifama zelanga zangaphandle nangona ixabiso liphezulu ngokuphindwe kathathu ukuya kwi-10 kwinxalenye nganye. Ukuphumelela kwe-TCO kuvela ekuphelisweni kwabasebenzi abatsha — eyona nto iphambili kwindleko — kunye nokuphepha ukusilela kolawulo lweentambo ezivela kwiintambo ze-nylon ezonakeleyo. Kwifama ye-100 MW enezintambo zentambo ezingama-200,000, i-TCO ye-nylon yeminyaka eli-10 yi-400,000-800,000 USD; i-TCO yentsimbi engagqwaliyo efanayo yi-150,000-300,000 USD. Inqanaba lokwahlulwa lixhomekeke kwimozulu (ubungakanani be-UV, ubushushu), iindleko zokufikelela kulondolozo, kunye noqeqesho lomjikelo wokutshintshwa komqhubi.

Iintambo zeCable zeBall-Lock Stainless Steel — imveliso yesalathiso esetyenzisiweyo kuthelekiso lwe-TCO yefama yelanga yangaphandle yeminyaka eli-10. Umthombo: Xinjing Stainless Steel Co., Ltd.

Kutheni Ukukhethwa kweCable Tie Kungumbuzo we-TCO, Kungenguwo Umbuzo Obalulekileyo

Xa iqela le-solar farm EPC livavanya iintambo zekhebula zolawulo lwentambo ye-DC, intambo yokuqokelela i-AC isebenza, kunye neentambo ze-homerun zephaneli ukuya kwi-inverter, isigqibo sidla ngokuqala njengombuzo wezinto eziphathekayo: i-nylon okanye intsimbi engatyiwayo. Umbuzo olandelayo - ukuba yeyiphi engabizi kakhulu - ngumbuzo ongalunganga. Umbuzo ochanekileyo ngulo: kwiminyaka eli-10 yoyilo lwefama yelanga esetyenziswayo, ixabisa malini yonke into, kuquka abasebenzi abatsha kunye neendleko zokungaphumeleli kweentambo ezonakaliswe yimeko?

Ukuphendula loo mbuzo ngento engaphezulu nje kwezimangalo zokuthengisa, sidibanise imodeli yexabiso lilonke leminyaka eli-10 yokuthelekisaiintambo zentsimbi engagqwaliyo(uhlobo lwebhola-lokhi, iigreyidi ezingama-304 kunye ne-316L) ngokuchasene neentambo ze-nylon ze-PA66 eziqhelekileyo (ezizinzileyo nge-UV nezingazinzanga). Le modeli ibandakanya iindleko zezinto, amaxesha okutshintsha, umsebenzi wokutshintsha, kunye neendleko zokungaphumeleli kweentambo ezonakaliswe kwifama yelanga eyi-100 MW emele umbane. Eli nqaku lihamba ngeengeniso zemodeli, izinto zeendleko, kunye nohlalutyo lokulinganisa.

Indawo Yokuchatshazelwa Yilanga Efama Yangaphandle

Ifama yelanga yangaphandle yenye yezona ndawo zinzima kuyo nayiphi na imveliso yolawulo lweentambo. Iintambo zihlala elangeni ngqo, zibona umjikelo wobushushu bemini, zinyamezela ubunzima besanti nemvula eqhutywa ngumoya, kwaye kwezinye iindawo zijongene nomonakalo weempuku kunye neentaka. Izinto ezine ezibangela ukonakala kwentambo kwinkonzo yeefama zelanga zezi:

• imitha ye-UV.I-Polyamide (nylon) yi-organic polymer; i-UV iyawaphula ama-amide bond ngokuhamba kwexesha, nto leyo ekhokelela ekuqhekekeni kwetyathanga, ekulahlekelweni kwamandla okutsalwa, nasekuphelelweni kokuqhekeka ekugqibeleni. I-nylon emnyama eqiniswe yi-UV yandisa ixesha lokuphela kwayo nge-30-50% kodwa ayisusi imo yokusilela.
• Ukujikeleza kobushushu.Amaqondo obushushu obuphezulu bephaneli yelanga elangeni lasehlotyeni afikelela kwi-70-85°C kwiindawo ezinemozulu epholileyo kunye ne-90°C+ kwiindawo zasentlango. Ubuncinane bobusika kwiindawo ezibandayo behla bufikelele kwi--30°C okanye ngaphantsi. Umjikelo wonyaka wobushushu ugxininisa yonke i-polymer kunye neentlobo ngeentlobo zesinyithi.
• Umswakama kunye netyuwa.Iindawo ezikunxweme, i-solar edadayo elunxwemeni, kunye neendawo ezishushu ezinomswakama ophezulu zibeka iintambo kwi-corrosion eqhutywa yi-chloride. I-nylon ifunxa amanzi kwaye itshintsha ubukhulu; i-stainless steel esemgangathweni ye-304 isengozini yokuqhekeka kwiindawo ezityebileyo nge-chloride.
• Oomatshini kunye nebhayoloji.Ukungcangcazela komoya, ukwanda kobushushu bentambo, ukuhlafuna iimpuku (ii-squirrels, iimpuku), kunye nomonakalo weentaka (ingakumbi ngexesha lokuzalela iintaka) konke oku kucinezela intambo ngeendlela ezingabanjwa ngayo iphepha ledatha.

Ezi zinto zine zixinzelelayo ziyadibana. Intambo ye-nylon ehlala iphila emva kokuvezwa yi-UV iminyaka emi-3 isenokungaphumeleli phantsi kohlaselo lwempuku kunyaka wesi-4. Intambo yentsimbi engagqwaliyo ephatha i-UV kunye nobushushu ngaphandle kwesikhalazo isenokonakala kwindawo edibanisa i-ball-lock kwindawo enesitshizi setyuwa elunxwemeni. Imodeli ye-TCO kufuneka iphathe uxinzelelo oludibeneyo, kungekuphela nje kwiphepha ledatha yezinto ezibonakalayo.

Iintambo zeCable zeStainless Steel: Ziyintoni kwaye zisebenza njani

Iintambo zentsimbi engagqwaliyo zenziwe ngokuchanekileyo ngentambo yentsimbi engagqwaliyo ebandayo, edla ngokuba yi-304 okanye i-316L.uhlobo lwebhola oluzitshixayoisebenzisa i-stainless steel ball bearing ebanjwe entlokweni etshixwayo; njengoko i-tie ixinene, ibhola ihlala kwindawo yokutshixwa kwaye i-tie itshixwa ngokusisigxina. I-tie ayinakuvulwa kwakhona ngaphandle kokusikwa, nto leyo efunekayo kulawulo lweentambo zefama zelanga apho i-tie iyinxalenye yendlela yentambo yexesha elide.

Amanqanaba aqhelekileyo ezinto ezisetyenziswa kwiintambo zefamu zelanga:

• Intsimbi engagqwaliyo engama-304.Umgangatho wehashe elisebenzayo kwiindawo ezingaphakathi elizweni, ezinomhlwa omncinci. Amandla okutsalwa yi-515-620 MPa kuxhomekeke kubushushu obubandayo; uluhlu lobushushu benkonzo luyi--80°C ukuya ku-+500°C rhoqo. I-304 lolona khetho lwe-stainless olunexabiso eliphantsi olufanelekileyo kwiindawo ezininzi zeefama zelanga.
• Intsimbi engagqwaliyo engama-316L.Ukhetho lomgangatho wolwandle kwiindawo ezikunxweme, kwiindawo ezishushu ezinomswakama ophezulu, kunye nayo nayiphi na imeko-bume engaphakathi kwe-5 km ukusuka kumthombo weekhemikhali zoshishino. Umxholo we-molybdenum oyi-2-3% uphucula kakhulu ukumelana ne-chloride pitting. I-316L idla ngokubiza ngaphezulu nge-30-50% kune-304.
• Intsimbi engagqwaliyo engama-201.Ukhetho olunexabiso eliphantsi ngamanye amaxesha lusetyenziswa kwizicelo ezingabalulekanga. Ukumelana nokugqwala okuphantsi kune-304 kwaye akukhuthazwa kwinkonzo yelanga yangaphandle efama.

Ikhathalogu yethu igubungela uluhlu olupheleleyo lwezintoiintambo zentsimbi engagqwaliyokuluhlu lwe-200, 300, 400 kunye neeklasi ze-duplex, kunye neendlela ze-epoxy-coated kunye ne-PVC-coated zokufakelwa apho kufuneka ukhuseleko olongezelelweyo lobushushu. Ithala leencwadi lezinto zentsimbi engagqwaliyo yeXinjing likwaxhasa intsimbi engaphantsi (egubungeleke ngokubandayo ngobukhulu obuyi-0.03-3.0 mm, ububanzi obuyi-10-600 mm) kumgca wokuvelisa intambo.

Iintambo zeNylon Cable: Ziyintoni kwaye Zingaphumeleli Njani

Iintambo ze-nylon cable — ezona zibophelelo zininzi ze-EPC farm farm eziqhelene nazo — zenziwe nge-injection-molded from polyamide 6.6 (PA66) kunye ne-UV stabilizer ekhethiweyo eyongeziweyo. Ezi ntambo zisebenzisa izinyo le-ratchet elihamba ngendlela enye elivaleka ngokusisigxina xa lixinene kwaye alinakuvulwa kwakhona ngaphandle kokusikwa. Iintambo ze-nylon eziqhelekileyo azibizi kakhulu (0.05-0.30 USD ngesiqwenga ngasinye ngobuninzi), kulula ukuzifaka, kwaye zinemibala ehambelana ne-UV resistance.

Iindlela zokungaphumeleli kweentambo ze-nylon kwinkonzo yelanga yangaphandle zibhalwe kakuhle:

1. Ukuqhekeka kwetsheyini okubangelwa yi-UV.Imisebe ye-UV iyawaphula amaqhina e-amide kumqolo we-polyamide. I-tie ilahlekelwa ngamandla okutsala kancinci kancinci kangangeenyanga, ize ilahlekelwe kubude ngokukhawuleza, ize iqhekeke kwaye ingasebenzi phantsi komthwalo.
2. Ukuxinana kobushushu.Ubushushu bukhawulezisa ukubola kwe-oxidative kwe-polyamide. Iindawo zefama zelanga ezinamaqondo obushushu aphezulu zihlala zibola ngokukhawuleza kuneendawo ezinemozulu epholileyo.
3. I-Hydrolysis.I-PA66 ifunxa amanzi (malunga ne-8-10% ngobunzima xa igcwele). Ukujikeleza okumanzi-komileyo kwiindawo ezifumileyo kukhokelela kwi-hydrolysis yee-amide bonds kunye nokulahleka kweempawu zoomatshini.
4. Ukudinwa koomatshini.Ukungcangcazela komoya, ukwandiswa kobushushu be-cable bundle, kunye nokuphathwa komfaki konke oku kungenisa umthwalo ojikelezayo. Ukumelana nokudinwa kwe-nylon kuphantsi kune-static tensile strength yayo.

Isikhokelo esiqhelekileyo soshishino kukuba iintambo ze-nylon xa zichatshazelwa yilanga efama yangaphandle zifikelela kwi-50% yokulahleka kwamandla okutsalwa kwi-UV kwiinyanga ezili-18-30 xa zichatshazelwa yi-UV, kunye nokuwohloka ngokupheleleyo (ukungasebenzi kakuhle) ngonyaka wesi-4-6 kuxhomekeke kwimozulu. Iindawo ezishushu (eMbindi Mpuma, e-Australia, eMzantsi-ntshona we-US) ziyakhawulezisa ixesha; iindawo ezibandayo zingayandisa. I-nylon emnyama ezinziswe yi-UV yandisa ixesha ngama-30-50%, kodwa ayihambelani nobude bexesha bentsimbi engagqwaliyo.

Imodeli ye-TCO yeminyaka eli-10

Kwimodeli ye-TCO, sisebenzisa ifama yelanga eyi-100 MW emele umbane osetyenziswayo kunye neentambo ezingama-200,000 ekufakweni kokuqala. Le modeli ibandakanya izinto ezine zeendleko: izinto, izinto zokutshintsha, umsebenzi wokutshintsha, kunye neendleko zokusilela. Le modeli ithatha ukuba umqhubi uqhuba ifama ubomi obupheleleyo boyilo beminyaka eli-10 kunye nomjikelo wolawulo lwentambo ye-DC ecwangcisiweyo kunye nomjikelo wolawulo lwentambo yokuqokelela i-AC kunyaka wesi-5.

Le modeli ibonisa ukuba iintambo zentsimbi engagqwaliyo ziyaphumelela kwi-TCO yeminyaka eli-10 nangona ixabiso lezinto ezisetyenzisiweyo liphezulu ngokuphindwe kathathu ukuya kwi-10 kwisiqwenga ngasinye. Ukuphumelela kuvela kwizinto ezintathu: ukususwa komsebenzi wokutshintsha (icandelo leendleko eziphambili), ukususwa kweendleko zokusilela (iintambo eziwohlokileyo kwiisekethe ezibalulekileyo), kunye nokususwa kweendleko zokulahla ekupheleni kobomi (intsimbi engagqwaliyo iyaphinda isetyenziswe, i-nylon iya kwindawo yokulahla inkunkuma).

Icandelo leendleko zezinto ezibonakalayo

Icandelo leendleko zezinto ezibonakalayo lilona nani liphambili eliqala ngalo uninzi lwamaqela e-EPC, kwaye lelona lenza i-nylon ibonakale ingabizi kakhulu kumphezulu. Nge-0.05-0.30 USD ngeqhekeza le-nylon kunye ne-0.50-1.50 USD ngeqhekeza le-stainless steel, into yomgca wezinto zentsimbi engagqwaliyo iphindwe kathathu ukuya kwi-10 yento yomgca we-nylon kwi-200,000-tie yokuqala. Kwifama ye-100 MW, oko kuthetha i-100,000-300,000 USD yentsimbi engagqwali xa kuthelekiswa ne-10,000-60,000 USD ye-nylon.

Umsantsa weendleko zezinto zokwakha uyavalwa ngexesha lomsebenzi njengoko iintambo ze-nylon zitshintshwa kwaye iindleko zokutshintshwa ziyanda. Ngonyaka we-4-6, iindleko zezinto ze-nylon eziqokelelweyo zidlule kwiindleko zokuqala zezinto zentsimbi engagqwaliyo. Ngonyaka we-10, iindleko ze-nylon eziqokelelweyo ziphindwe kathathu ukuya kahlanu kwiindleko zentsimbi engagqwaliyo, nangaphambi kokuba kongezwe umsebenzi.

Umsebenzi Wokutshintsha: Icandelo Eliphambili le-TCO

Icandelo lomsebenzi otshintshiweyo lelona candelo likhulu kuluhlu lweminyaka eli-10 kwimodeli ye-TCO. Ukutshintshwa kwentambo yentambo kwifama yelanga esetyenziswa kakhulu kufuna izixhobo zokufikelela (i-cherry picker okanye i-scissor lift), ixesha lokuhamba ukuya kwindawo yentambo engaphumelelanga, intambo yokutshintsha ngokwayo, kunye nexesha lokufaka. Ixabiso lomsebenzi lilonke yi-1.5-3.5 USD ngentambo xa kubandakanywa izixhobo zokufikelela kunye nokuhamba.

Intambo yokubopha ngokwayo yi-0.05-0.30 USD kwi-nylon okanye i-0.50-1.50 USD kwintsimbi engagqwaliyo.Umsebenzi uphindwe kahlanu ukuya kwi-10 ixabiso lezinto ze-nylon kwaye ulingana phantse nexabiso lezinto zentsimbi engagqwaliyo.Isabelo sabasebenzi se-TCO sisizathu sokuba isisombululo esinexabiso eliphezulu lezinto eziphathekayo siphumelele kwiindleko zizonke: sisusa abasebenzi, kungekuphela nje izinto eziphathekayo.

Kwifama eyi-100 MW ene-200,000 ties kunye ne-10% ye-nylon replacement yonyaka, iindleko zomsebenzi zonyaka ziyi-30,000-70,000 USD. Kwiminyaka engaphezu kwe-10, abasebenzi bokutshintshwa kwe-nylon abaqokelelweyo yi-300,000-700,000 USD. Ifama efanayo ene-stainless steel ties kunye ne-0-1% ye-annual replacement ine-10-year work cost ye-0-70,000 USD. I-labor delta yodwa yi-230,000-630,000 USD xa kuthelekiswa ne-stainless steel.

Ixabiso lokusilela: Into yoMgca ofihliweyo

Icandelo leendleko zokusilela yinto ethathwa njengengamkelekanga kakhulu ngamaqela amaninzi e-EPC. Intambo ye-nylon eyonakeleyo ayiwi nje kakuhle - ikhulula i-cable bundle kancinci kancinci, ivumela intambo ukuba ihambe, ikruquke, kwaye ekugqibeleni iphose. Iindlela zokusilela ezivela kwintambo ye-cable eyonakeleyo kwifama yelanga ziquka:

• Impazamo yomhlaba.Intambo yentambo ye-DC elahlekelwa yintambo yayo ize iqhagamshelane ne-racking okanye isakhelo sephaneli idala isiphene somhlaba esiphazamisa i-inverter kwaye sivale umtya de kube kungenelelo olwenziwe ngesandla.
• Impazamo ye-arc.Ijakethi yentambo yeDC ekhuhliweyo evezwe yitayi ekhululekileyo inokubangela impazamo ye-arc, nto leyo eyingozi yomlilo kwiimeko zezityalo ezomileyo.
• Umonakalo wekhebula.Ukunyakaza okuphindaphindiweyo kwe-cable bundle engakhuselekanga nxamnye ne-racking kuyayisusa ijakethi kwaye kuveze umqhubi.
• Ukunqamka kwentambo.Umtya oqhawukileyo okanye oneziphene unciphisa imveliso yokuvelisa ifama de kube kutshintshwe iqhina kwaye intambo iqiniswe kwakhona.

Ixabiso elichazwe lishishini lesiganeko esinye sokusilela kwentambo kwifama yelanga esetyenziswa kakhulu yi-500-3,000 USD xa zonke izinto zibandakanyiwe (ixesha lokuxilonga, indawo yokutshintsha, isizukulwana esilahlekileyo, iqela lokulungisa). Ifama ene-200,000 nylon ties kunye ne-10% yokutshintshwa ngonyaka inokulindela iziganeko ezingama-30-80 ground fault okanye arc fault ngonyaka ezivela kwii-faults ezonakeleyo. Kwiminyaka engaphezu kwe-10, iindleko zokusilela eziqokelelweyo ze-nylon yi-50,000-150,000 USD; kwintsimbi engagqwaliyo, inani elilinganayo yi-0-15,000 USD.

Ubuthathaka kwiMozulu: Kutheni Iindawo ezishushu nezomileyo neziselunxwemeni zikhetha i-Stainless

Imodeli ye-TCO yeminyaka eli-10 inovelwano kwimozulu. Izinga lokutshintshwa kwe-nylon eliyi-8-15% ngonyaka liphakathi kwengingqi eshushu; iindawo ezishushu nezomileyo neziselunxwemeni zibona amazinga aphezulu. Amazinga okutshintshwa okulungiswa kwemozulu ngala:

Imodeli ye-TCO yeminyaka eli-10 kwiindawo ezishushu nezingenamanzi ijonge kakhulu kwintsimbi engagqwaliyo. Ngezinga lokutshintshwa kwenylon le-15% ngonyaka, iindleko zomsebenzi wenylon eziqokelelweyo kwiminyaka eli-10 ziphakathi kwe-450,000-1,050,000 USD — iphezulu kakhulu kunexabiso lezinto zentsimbi engagqwaliyo ze-100,000-300,000 USD. Iindawo ezikunxweme olushushu ziyamangalisa nangakumbi: intsimbi engagqwaliyo ye-316L yeyona ndlela isebenzayo yokusingqongileyo kolwandle, kwaye izinga lokutshintshwa kwenylon lenza inylon ingabi namandla ngokwezoqoqosho.

Ukuphindaphinda Kokutshintshwa: Umqhubi Ozolileyo

Utshintsho oluphindaphindwayo luyimbangela ethuleyo yemodeli ye-TCO. Ayilonani eliphambili, kodwa yinto emiselweyo egqiba ukuba ixabiso leminyaka eli-10 lilawulwa zizinto okanye ngumsebenzi. Utshintsho oluphindaphindwayo luxhomekeke kwizinto ezintathu:

1. Ukuchatshazelwa yimozulu.I-UV, ukujikeleza kobushushu, kunye nokufuma konke oku kukhawulezisa ukuwohloka kwe-nylon. Ukuphindaphinda kokutshintshwa kususela kwi-5% ngonyaka kwiindawo ezibandayo ukuya kwi-22% ngonyaka kwiindawo ezishushu eziselunxwemeni.
2. Umgangatho wokufakelwa.Iintambo zenylon eziqiniswe kakhulu ziyasilela ngokukhawuleza kuba ziqala ngoxinzelelo lwangaphakathi oluphezulu. Iintambo ezingaqiniswe kakhulu zivumela i-bundle ukuba ishukume kwaye ikhuhle. Uxinzelelo olufanelekileyo lokufakela lulwazi olufundwayo lokufakela.
3. Ukufikelela kulondolozo.Iindawo ezinofikelelo olubi kulondolozo (iindawo zelanga ezidadayo, iindawo eziphakamileyo, ukufakelwa kwentlango ekude) zibona iindleko eziphezulu zomsebenzi wokutshintshwa nge-tie nganye kuba izixhobo zokufikelela kunye nexesha lokuhamba liphezulu.

Kwabasebenzi befama yelanga abaneeshedyuli zolondolozo ezicwangcisiweyo kunye nokufikelela kakuhle, izinga lokutshintshwa kwenayiloni linokugcinwa kwinqanaba eliphantsi loluhlu. Kwabasebenzi abanexesha lokugcinwa elilibazisekileyo okanye ukufikelela okungafanelekileyo, izinga lokutshintshwa liphezulu okanye ngaphezulu. Imodeli ye-TCO isebenzisa i-10% njengendawo ephakathi yemozulu epholileyo; abasebenzi kufuneka bahlengahlengise ngokusekelwe kwidatha yabo yolondolozo.

Ukukhethwa kwezinto: 304, 316L, okanye i-Epoxy-Coated

Ukukhethwa komgangatho wentsimbi engagqwaliyo sisigqibo sesibini se-TCO esidibanisa impumelelo ephambili ye-TCO. Kwiindawo ezininzi zefama zelanga ezingaphakathi elizweni, intsimbi engagqwaliyo engama-304 lukhetho olungabizi kakhulu kwaye imodeli eqhelekileyo ye-TCO yeminyaka eli-10 engentla isebenzisa i-304. Kwiindawo eziselunxwemeni, ezinomswakama ophezulu, okanye ezitshatyalaliswa yimizi-mveliso, i-316L lukhetho lomgangatho wolwandle kwaye iindleko ezongezelelweyo zezinto ezingama-30-50% zihlawulelwa ngokutshintshwa okuncitshisiweyo okuqhutywa kukutsha.

Kwizinto ezifakelwayo apho ijakethi yekhebula ibuthathaka kumonakalo woomatshini, izibopho zentsimbi engagqwaliyo ene-epoxy okanye ene-PVC zongeza umaleko okhuselekileyo kwi-insulation. I-coating yongeza i-20-40% kwixabiso lezinto kodwa isusa umngcipheko wokusikwa kwe-insulation. Kwiintambo ze-DC string ezine-insulation eqhelekileyo ye-XLPE, i-304 engagqunywanga yanele. Kwiijakethi zekhebula ezibuthathaka (TPE, iikhompawundi ezithile ze-PVC), i-epoxy-coated yeyona ndlela ikhuselekileyo.

Indlela ii-RFPs zeFama yeSolar yokwenyani ezichaza ngayo iintambo zekhebula

Ii-RFP ezimbini zakutshanje zefama yelanga ezifike edesikeni yethu zibonisa indlela eyenzeka ngayo xa kukhethwa izinto:

I-RFP yefama yelanga ye-Q4 2025 yokufakelwa kwe-100 MW eMzantsi-ntshona we-US ichaze "iintambo ze-304 zentsimbi engagqwaliyo, ububanzi obuyi-4.6 mm, ubude obuyi-200-360 mm, ukumelana ne-UV, ubomi boyilo obuhambelana neminyaka engama-50." I-RFP ayizange ifake i-nylon njengenye indlela eyamkelekileyo; iqela loyilo le-EPC lalisele ligqibe kwelokuba i-TCO yeminyaka eli-10 ithanda intsimbi engagqwaliyo kwimozulu eshushu neyomileyo.

I-RFP yefama yelanga edadayo yeQ1 2026 yokufakelwa kwe-25 MW kunxweme oluseMzantsi-mpuma weAsia ichaze "iintambo ze-316L zentsimbi engagqwaliyo, ububanzi obuyi-4.6 mm, zigqunywe ngokupheleleyo, imeko-bume yolwandle ilinganiswe." Indawo-bume yolwandle kunye nemozulu enomswakama ophezulu yenze i-316L yaba lolona khetho lusebenzayo lwe-stainless stainless; i-304 ibiya kuba igugile kwindawo yokudibanisa i-ball-lock kwiminyaka emi-5-7.

Zombini ii-RFP zibonisa indlela esebenza ngayo imboni: ukukhethwa kwezinto ezibotshelelwe ngentambo kuqhutywa ngakumbi luhlalutyo lweendleko zomjikelo wobomi endaweni yexabiso eliphambili. Ixabiso lezinto ezisetyenziswayo eliyi-3-10x lentsimbi engagqwaliyo liqondwa kakuhle ngamaqela athengayo asebenza kwiifama zelanga ezisetyenziswa kakhulu; ukuphumelela kwe-TCO yikona okuqinisekisa ukuba ixabiso lelo liphezulu.

Yintoni Omele Uyicacise kwi-RFP yeCable Tie yakho

Kumaqela okuthenga iifama zelanga abhala iinkcukacha zentambo, imigca emine yeenkcukacha ebaluleke kakhulu yile:

1. Udidi lwezinto eziphathekayo.“Intsimbi engagqwaliyo engama-304, intsimbi engagqwaliyo engama-316L, okanye i-nylon ye-PA66 ene-UV stabilizer.” Cacisa uhlobo, hayi nje “engenasinxibo” okanye “ineyiloni.” Intsimbi engagqwaliyo engama-201 ngamanye amaxesha inikezelwa njengendlela eyahlukileyo kodwa ayikhuthazwa kwinkonzo yangaphandle yelanga efama.
2. Indlela yokutshixa.“Uhlobo lwebhola olutshixwayo, oluzitshixayo, olusetyenziswa kanye.” Cacisa indlela yokutshixa ukuze uphephe ukufumana iintambo ezifana nezeleli okanye ezikhululekayo ezingenzelwanga ulawulo olusisigxina lwentambo.
3. Ubukhulu.“Ububanzi be-4.6 mm, uluhlu lobude oluhambelana nobubanzi be-bundle.” Cacisa ububanzi nobude, hayi nje “intambo ebotshelelweyo.” Ububanzi yeyona nto iphambili ebangela amandla okutsalwa; ubude kufuneka bufaneleke kwi-bundle.
4. Uvavanyo lokusingqongileyo.“Ayina-UV, ikwinqanaba lolwandle (kwiindawo eziselunxwemeni), ubushushu obuphakathi -40°C ukuya ku +85°C ubuncinane.” Cacisa umlinganiselo wokusingqongileyo ukuqinisekisa ukuba iintambo zifanelekile kwiimeko zendawo.

Kuzo zombini izixhobo, cela isampula eninzi ukuze ihlolwe ngaphambi kokuba ufake iodolo epheleleyo. Isampulu kufuneka ibandakanye uvavanyo lwamandla okutsalwa (intambo kufuneka ibambe i-80% yomthwalo omncinci wokutsalwa) kunye nokuhlolwa ngokubonakalayo (akukho ziphene zomphezulu, akukho zikhefu zokugquma kwiintambo ezigqunyiweyo). Kwiindawo zefama zelanga ezinolawulo lweentambo ezibalulekileyo, inyathelo lokuhlola elingenayo lelona libalulekileyo lokulinganisa i-QC.

Ukuzinza kunye nokuphela kobomi

Zombini ezi zinto zinento ezicinga ngayo xa ziphela, kodwa zahlukile ngobukhulu. Intsimbi engatyiwayo ingasetyenziswa kwakhona ngokupheleleyo kwaye umxholo ophinda usetyenziswe wentsimbi entsha engatyiwayo uhlala uphakathi kwama-60-90% (kuxhomekeke kumvelisi). Ekupheleni kwexesha lokusebenza kweminyaka eli-10, iintambo zentsimbi engatyiwayo zinokufunyanwa njengeenkunkuma kwaye ziphinde zifakwe kwikhonkco lobonelelo lwentsimbi engatyiwayo ngaphandle kokulahlekelwa ziimpawu zezinto ezibonakalayo.

Iintambo ze-nylon zihlala zigcwala emhlabeni ekupheleni kobomi bazo. I-PA66 inokuphinda isetyenziswe ngobuchwephesha kodwa uqoqosho lokuqokelela nokulungisa iintambo ezincinci ezivela kwifama yelanga esasazekileyo alunamdla. Uninzi lwabasebenzi lufaka iintambo ze-nylon ezisetyenzisiweyo njengenxalenye yomjelo wokususa inkunkuma.

Isigqibo sozinzo phakathi kwentsimbi engagqwaliyo kunye ne-nylon asisosizathu siphambili se-TCO, kodwa siyinxalenye yesigqibo sokuthenga abaqhubi abaneemfuno ze-ESG. Ixabiso lokulahla i-nylon (malunga ne-20,000 USD kwifama ye-100 MW kwiminyaka eli-10) yinto encinci, kodwa uphawu lwekhabhoni kwindlela yokulahla luyinxalenye yokukhutshwa kwe-Scope 3 ebanzi ebalwa ngabanye abaqhubi.
