Cov Lus Qhia Rau Kev Siv Cov Hlau Refractory?

BV hlau feem ntau hu ua yas tooj liab hlau. Feem ntau, nws yog tsuas yog siv rau ib leeg-core hard hluav taws xob conductors yam tsis muaj sheathing nyob ntawm tej thiab cables. Nws muaj cov yam ntxwv ntawm cov kua qaub thiab alkali tsis kam, hnav tsis kam, tsis muaj dej, thiab tshem tawm mildew. Nws yog dav siv nyob rau hauv tsev neeg.

Ua ntej, hom BV kab

ZC-BV: Cable tooj liab hlau PVC insulated nplaim retardant cable: Cov khoom insulating yog ntxiv nrog cov nplaim hluav taws tsis muaj halogen, thiab nws yuav tsis ntes hluav taws thaum nws tawm mus.

ZC-BV: Kev tiv thaiv BV kab yog muab faib ua plaub theem: A, B, C, thiab D. Ntawm lawv, hom A yog qhov zoo, thiab lwm yam. Nws yog feem ntau siv raws li ZC-BV.

N-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 specifications ntawm BV kab

BV kab feem ntau siv qhov chaw hla ntawm cov tub ntxhais hlau tus neeg xyuas pib ntawm cable sheath kom paub qhov txawv cov qauv thiab cov qauv. (Piv txwv li, txoj kab uas hla ntawm cov tooj liab seem ntawm 4 square meter BV hlau cable yog 2.25mm, raws li cov qauv hauv cheeb tsam annular S=π * r * r=3.976mm²)

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 meters, 50 square meters, 70 square meters, 95 square meters, 120 square meters, 150 square meters, 185 square meters, 240 square meters, thiab lwm yam.

Thib peb, qhov txiaj ntsig ntawm BV kab

BV kab muaj cov yam ntxwv ntawm cov kua qaub thiab alkali tsis kam, hnav tsis kam, tsis muaj dej, tshem tawm mildew, thiab lwm yam. Nws yog feem ntau yog siv rau ib leeg-core nyuaj hluav taws xob conductor unsheathed cables, haum rau lub zog hluav taws xob nrog AC tam sim no ntawm 450/750V thiab hauv qab no. , txhua hnub cov khoom siv hluav taws xob muaj zog, cov cuab yeej ntsuas hluav taws xob thiab cov xov hlau thiab cov kab hluav taws xob siv hauv cov khoom sib txuas lus.
