PV kab yog tsim thiab sim rau DC sab ntawm photovoltaic systems, nrog rau raug tshav ntuj, tshav kub, noo noo thiab sab nraum zoov kub mus txog. "Ib txwm kab" yog ib lo lus dav dav uas npog ntau yam dav dav - lub hom phiaj cables, yog li nws tsis tuaj yeem txiav txim siab tsim nyog lossis tsis haum.
Yog li ntawd,Dab tsi yog qhov txawv ntawm PV Cable thiab ib txwm Cable?Nov yog cov ncauj lus kom ntxaws txog qhov sib txawv tseem ceeb:
1. Khoom siv thiab rwb thaiv tsev
- PV Cables:Cov no yog cov cables tshwj xeeb uas feem ntau sivirradiation -crosslinked polyolefin(feem ntau tsawg- pa taws, xoom- cov ntaub ntawv halogen) rau ob qho tib si rwb thaiv tsev thiab sheathing. Qhov kev kho tshwj xeeb no hloov cov qauv molecular, muab tshwj xeeb tiv thaiv UV rays, huab cua kub, tshuaj, thiab ozone. Lawv kuj nquag siv tinned tooj liab conductors los txhim kho corrosion kuj.
- Tej Cables:Standard cables feem ntau sivPVC (polyvinyl chloride)los yog tsis tu ncua crosslinked polyethylene (XLPE) rau rwb thaiv tsev thiab sheathing. Thaum tus nqi- zoo, PVC tsis muaj kev tiv thaiv UV ruaj khov thiab tuaj yeem ua nkig, tawg, lossis yaj thaum raug rau sab nraum zoov hnyav.
2. Environmental Durability thiab Temperature Tolerance
- PV Cables:Tsim tshwj xeeb rau qhov chaw sab nraum zoov hnyav, PV cables tuaj yeem tiv taus lub hnub ncaj qha, nag, thiab kub hloov pauv. Lawv feem ntau ua haujlwm nyab xeeb hauv qhov kub thiab txias, los ntawm-40℃rau +90 degree, nrog lub ncov kub tsis kam ncav mus txog120 degree.
- Tej Cables:Lub hom phiaj feem ntau yog rau qhov chaw nyob sab hauv lossis ruaj khov, cov kab hluav taws xob ib txwm muaj qhov ntsuas kub qis dua (feem ntau nyob ib puag ncig 70℃rau PVC). Nyob rau hauv huab cua kub, lawv cov rwb thaiv tsev tuaj yeem muag los yog yaj, thiab nyob rau hauv qhov chaw khov, lawv tuaj yeem ua kom tawv thiab tawg.
3. Kev ua neej nyob thiab kev nyab xeeb
- PV Cables:Ua tau ntev -lub sij hawm sab nraum zoov kev cia siab, PV cables yog engineered kom phim lub lifespan ntawm lub hnub ci vaj huam sib luag system, feem ntau kav ntev25 xyoo los yog ntau tshajtsis muaj qhov tseem ceeb degradation. Lawv kuj muaj cov nplaim hluav taws zoo tshaj -cov khoom siv hluav taws xob thiab qis- cov pa taws los txhim kho kev nyab xeeb hluav taws.
- Tej Cables:Thaum siv sab nraum zoov, cov cables ib txwm degrade sai vim yog UV raug thiab huab cua, ua rau muaj kev saib xyuas tsis tu ncua, tawg, thiab muaj feem cuam tshuam hluav taws xob xws li luv luv. Lawv tag nrho lifespan nyob rau sab nraum zoov siv hnub ci yog luv luv.
4. Kev ua haujlwm hluav taws xob
- PV Cables:Optimized los tswj siab -voltage direct tam sim no (DC) zoo. Lawv tau tsim los txo qis hluav taws xob poob rau qhov ntev thiab tuaj yeem pab txhawb DC voltages siab (txog 1,500V lossis ntau dua).
- Tej Cables:Feem ntau tsim los rau qis dua -voltage alternating tam sim no (AC) daim ntawv thov (feem ntau txog 600V AC). Siv lawv nyob rau hauv siab -voltage solar systems yuav ua rau overheating, siab zog poob, thiab muaj kev nyab xeeb txaus ntshai.
5. Daim ntawv thov Scenarios
- PV Cables:Tsuas yog siv nyob rau hauv lub hnub ci fais fab kev sib txuas hnub ci vaj huam sib luag, lub thawv sib txuas, thiab cov tshuab hluav taws xob, kom ntseeg tau tias muaj kev nyab xeeb thiab muaj txiaj ntsig DC hluav taws xob xa mus rau sab nraum zoov.
- Tej Cables:Dav siv rau kev siv hluav taws xob sab hauv tsev, teeb pom kev zoo hauv tsev, khoom siv hauv tsev, thiab cov qauv kev lag luam hauv tsev hluav taws xob.
Cov lus hauv qab no qhia meej txog qhov sib txawv ntawm lawv; Kuv xav tias nws tuaj yeem qhia kojyuav ua li cas xaiv photovoltaic cables.
