BV hlau feem ntau hu ua yas tooj liab hlau. Nws feem ntau yog siv rau ib leeg-core hard conductor hlau thiab cable tsis muaj sheath. Nws muaj cov yam ntxwv ntawm cov kua qaub thiab alkali tsis kam, hnav tsis kam, dej tsis kam, thiab mildew tshem tawm. Nws yog dav siv (cov khoom siv hauv kev lag luam, kev tsim vaj tsev, kev tsim kho, thiab lwm yam) kho kom zoo nkauj, lub hwj chim txee, hloov txee, lub thawv fais fab, teeb pom kev zoo).
Hom, qauv specification, thiab lub hom phiaj tseem ceeb ntawm BV kab.
1. Hom BV kab
ZR-BV: cable tooj liab hlau PVC insulated nplaim retardant cable: cov khoom insulating yog ntxiv nrog nplaim retardant, thiab nws yuav tsis ntes hluav taws thaum nws siv tam sim ntawd.
ZR-BV nplaim taws retardant qib: nplaim retardant BV hlau muab faib ua peb theem: A, B, thiab C. Ntawm lawv, chav kawm ntawv A yog qhov zoo tshaj plaws, thiab lwm yam, thiab nws yog feem ntau siv raws li ZR-BV.
NH-BV: cable tooj liab hlau PVC insulated hluav taws-resistant hlau: nws tuaj yeem pib ib txwm nyob rau hauv qhov chaw ntawm hluav taws kub.
2. Qauv specification ntawm BV kab
BV kab feem ntau siv qhov chaw hla ntu ntawm cov tub ntxhais hlau tus neeg xyuas pib ntawm lub cable sheath kom paub qhov txawv qhov tshwj xeeb thiab qauv. (Piv txwv li, qhov hla-sectional aperture ntawm tooj liab hlau ntawm 4 square meter BV kab cable yog 2.25mm, raws li cov qauv hauv cheeb tsam ncig S=π * r * r=3.976mm2)
Feem ntau siv bv kab qauv specifications:
0.75 square meters, 1 square meters, 1.5 square meters, 2.5 square meters, 4 square meters, 6 square meters, 10 square meters, 16 square meters, 25 square meters, 35 square meters, 50 square meters, 70 square meters, 95 square meters, 120 square meters, 150 square meters, 185 square meters, 240 square kuvters, lwm.
