nruab nrab voltage fais fab cable yog tsim rau nruab nrab voltage fais fab kis scenarios thiab muaj qhov zoo xws li kev sib kis ntev thiab muaj peev xwm kis tau tus mob loj. Qhov hluav taws xob tiv taus theem nruab nrab voltage cables feem ntau yog 0.6/1kV rau 26/35kV, haum rau cov khoom siv hluav taws xob sib txawv thiab lub sijhawm.
Muaj ntau hom kab hluav taws xob nruab nrab raws li cov qauv sib txawv. Raws li cov khoom siv hluav taws xob, qhov nruab nrab voltage xaim tuaj yeem muab faib ua tooj liab nruab nrab voltage cables thiab aluminium nruab nrab voltage cables; Raws li cov khoom siv rwb thaiv tsev, nws tuaj yeem muab faib ua polyethylene insulated nruab nrab voltage cables, cross-linked polyethylene insulated nruab nrab voltage cables, thiab roj hmab insulated nruab nrab voltage cables; Raws li cov qauv, nws tuaj yeem muab faib ua ib leeg tub ntxhais nruab nrab voltage cables thiab multi-core medium voltage cables; Raws li lawv cov kev siv, lawv tuaj yeem muab faib ua ob hom: mv cable rau hauv nroog cov phiaj xwm hluav taws xob, nruab nrab hluav taws xob fais fab cable rau kev lag luam, nruab nrab voltage cables rau kev siv mining, thiab nruab nrab voltage cables rau petrochemical siv.
Thaum xaiv cov kab hluav taws xob nruab nrab, cov hauv qab no yuav tsum tau xav txog:
Cable cross-sectional cheeb tsam: Lub cheeb tsam cross-sectional ntawm lub cable yog txiav txim raws li lub hwj chim thiab tam sim no yuav tsum tau ntawm cov khoom siv hluav taws xob kom muaj kev ruaj ntseg kis tau tus mob ntawm txaus tam sim no.
Cov khoom siv rau cov cables: Xaiv cov ntaub ntawv tsim nyog (tooj liab lossis txhuas) thiab cov ntaub ntawv rwb thaiv tsev (polyvinyl chloride, cross-linked polyethylene, thiab lwm yam) raws li kev siv scenario thiab tam sim no.
Voltage resistance theem ntawm cables: Xaiv qhov sib thooj voltage kuj theem raws li qhov yuav tsum tau voltage ntawm cov khoom siv hluav taws xob.
Txoj kev tso kab hluav taws xob: Xaiv txoj kev tsim nyog (kev faus ncaj qha, kav dej, choj, thiab lwm yam) raws li kev siv scenario thiab ib puag ncig.
