Photovoltaic DC cables yog tus cwj pwm los ntawm UV tsis kam, siab thiab kub tsis kam, kev laus ua haujlwm, lub zog ua haujlwm siab, thiab kev ua haujlwm hluav taws xob zoo heev, thiab tshwj xeeb yog tsim rau ntev - lub sijhawm ua haujlwm sab nraum zoov ntawm lub hnub ci zog.
Cov cables no feem ntau siv cov tin-plated tooj liab conductors los tiv thaiv oxidation zoo thiab ua kom cov conductivity stability. Cov ntaub ntawv rwb thaiv tsev thiab cov ntaub qhwv feem ntau yog hla- txuas polyolefin (XLPE) lossis qis- pa taws halogen- cov ntaub ntawv tsis pub dawb, hla- txuas los ntawm cov kab hluav taws xob hluav taws xob, muaj huab cua tiv thaiv zoo thiab nplaim hluav taws.
Lawv qhov kev ua haujlwm kub ib txwm yog -40℃rau +125 degree, tso cai rau lawv tiv taus huab cua huab cua, thiab lawv lub neej kev pab ntau tshaj 25 xyoo, piv rau lub neej tsim ntawm photovoltaic fais fab nroj tsuag.
Tsis tas li ntawd, photovoltaic DC cables yuav tsum dhau cov ntawv pov thawj thoob ntiaj teb xws li TÜV 2Pfg 1169/08.2007 kom ntseeg tau tias muaj kev nyab xeeb nyob rau hauv siab DC voltages (piv txwv li, 1800V).
