Qhov sib txawv ntawm photovoltaic cables thiab cov cab xwm dog dig
Photovoltaic cable yog ib txoj kab tshwj xeeb rau hnub ci photovoltaic cables, nrog rau cov qauv xws li PV1-F,H1Z2Z2-K.Dab tsi yog qhov txawv ntawm hnub ci photovoltaic kab thiab cov xov hlau zoo tib yam? Vim li cas ho tsis tuaj yeem siv cov xov hlau zoo tib yam siv rau hnub ci photovoltaic fais fab tuag?
Hauv qab no, peb yuav sib piv thiab txheeb xyuas qhov sib txawv ntawm tus neeg xyuas pib, rwb thaiv tsev, sheath, thiab daim ntawv thov scenarios ntawm cov hlau.
【Conductor】
Photovoltaic cable: Copper conductor lossis tinned tooj liab conductor
Zoo tib yam cable: tus neeg kos npe tooj lossis tinned tooj tooj tooj liab
Rwb thaiv tsev 【
Photovoltaic cable: irradiated cross-txuas Polyolefa rwb thaiv tsev
Cov Cables dog dig: insulated nrog polyvinyl chloride (PVC) lossis hla cov polyethylene
【Khoom】
Photovoltaic cable: irradiated cross-txuas Polyolefa rwb thaiv tsev
Ordinary cable: PVC sheath
Los ntawm cov lus qhia saum toj no, peb tuaj yeem nrhiav tau cov xov hlau thiab cov xov hlau zoo tib yam muaj tib tus neeg saib xyuas, tab sis lawv qhov sib txawv yog cov khoom ntawm lawv cov ntaub qhwv ntsej muag thiab sheath.
Radiation Crosslinked polyolefin muaj cov kev yoog raws ib puag ncig, thiab kub ua tsis kam, nrog qhov ntsuas kub siab tshaj plaws ntawm 125 degree.
Polyvinyl chloride (PVC) muaj qhov zoo ntawm cov qauv kev ruaj ntseg, muaj cov tshuaj tiv thaiv siab, muaj zog siv zog, thiab rwb thaiv tsev rwb thaiv tsev. Txawm li cas los xij, pvc muaj cov tsis zoo rau lub teeb thiab kub, nrog qhov ntsuas kub tshaj plaws ntawm 55 degree.
Hla txuas polyethylene muaj cov qauv sib txuas thiab kev ua haujlwm kub zoo heev. Nws cov rwb thaiv tsev kev ua tau zoo yuav tsum siab dua li cov khoom siv PE. Lub hardness, nruj, hnav tsis kam, thiab cuam tshuam tsis kam ntawm cov khoom siv kho tshuab tau zoo dua. Tshuaj tiv thaiv, muaj zog acid thiab alkali tsis kam, thiab roj kuj. Qhov siab tshaj plaws ntsuas kub yog 90 degree.
Vim qhov tshwj xeeb ntawm cov tshuab hluav taws xob photovoltaic, muaj cov kev cai tshwj xeeb rau cov kab photovoltaic. Cov kab photovoltaic yuav tsum muaj huab cua tsis kam, kub tsis kam, kev sib txhuam tsis kam, UV hluav taws xob tiv thaiv, ozone tsis kam, hydrolysis tsis kam, acid tsis kam, ntsev tsis kam, thiab lwm yam, thiab irradiated cross-linked polyolefins ua tau raws li tus yam ntxwv no. Polyvinyl chloride (PVC) los yog ntoo khaub lig-txuas polyethylene rwb thaiv tsev muaj me ntsis tshav kub tsis kam tshaj irradiated cross-linked polyolefin rwb thaiv tsev, yog li cov xov hlau zoo tib yam tsis tuaj yeem siv rau cov kab photovoltaic.
