预制分支电缆具有供电可靠､价格便宜､安装简便､环境要求低等特点,因此在国内外得到了广泛的推广应用｡目前国内外预制分支电缆的研制与生产已相当成熟,工艺比较先进｡预制分支电缆可在住宅楼､办公楼､宾馆､医院商场等高层建筑广泛应用,而且已扩展到公路､桥梁及隧道照明等其它领域｡预制分支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,在工厂内用一系列专用设备､在流水生产线上将其定作完成的带分支电缆｡
Prefad branch cables have many characteristics such as: power supply is reliable, price is cheap, installing is simple and convenient, environmental demand is low and so on, so it gets wide application and dissemination at home and abroad. At present, at home abroad, the research and production of prefab branch cables have quite matured, the technology has got advanced, prefab branch cables not noly can be wildly applied to the tall buildings: dwelling house buildings, office buildings, guesthouses, hospitals, 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, prefab 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 wher the worker use a series of special purpose equipments.
● 预制分支电缆型号和规格说明: Prefad branch power cables type and specification explanation：
● 使用特性
1)额定电压为U0/U为0.6/1kv
The rated voltage U0/U is 0.6/1kv
2)电缆导体的长期允许工作温度
PVC绝缘应不超70℃
XLEP绝缘应不超90℃
The permissible long-term working temperature of cable conductor;
relative to the PVC insulated cable, it must be below 70℃;
relative to the XLPE insulated cable, it must be below 90℃
3)予制分支电力电缆敷设时环境温度不低于0℃,允许弯曲半径为电缆外径的30倍｡
When laying prefab branch power cables,ambient temperature of laying is not less than 0℃, permissive bending radius is 30 times of cable outer diameter。
