　　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 where 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℃
