预制分支电力电缆-山西通用电缆科技有限公司手机版

详细介绍

用途 Application

预制分支电力电缆可在住宅楼、办公室、宾馆、医院、商场等高层建筑使用，而且已扩展到公路、桥梁及隧道照明灯其它领域。预制分支电力电缆作为一种新型建筑用线，是工厂按照用户要求的主、分支电缆型号、截面、长度及分支位置等指标，经过专业的一系列设备、生产流水线将其完成的带分支的电缆。

The prefad branch electrical power cable can be wildly applied to the tall buildings:dwelling house buildings,office buildings,guesthouses,hospital markets and so on,but also has expanded to the other realm:highway,bridge and tunnel illumination and so on.As a new type of building cable,prefad branch cables are produced according to the targets of consumer’s demands:type of the main and the branch cable,cross section,length and branch position,they are finished on the assembly line in the factory where the worker use a series of special purpose equipments .
