技术数据
The Main Technical Data 母线槽与电缆供电系统比较
Comparision Between the Busbar and the Cable in Power Distribtion
本公司生产的各种系列母线槽，适用于高层建筑，多层工业厂房，机床密集的车间，产品工艺多变的车
间，老车间及厂房的改造，各种实验室、展览馆、体育馆、宾馆、银行、娱乐等场所作电力馈电及配电使 方便、安全、可靠
用。具有安全可靠，安装方便，施工灵活，体积小容量大，设计施工周期短，使用寿命长等特点，具体的技 对于高层建筑，母线槽系统的技术和经济优势显得特别明显。它不用为每个层面设计和敷设独立的电缆，整个大
术数据见下表： 楼仅需单一母线供电，将插接箱插入母线槽系统即可为每层楼供电，这显然比使用电缆更安全、更简单、更可靠。
The various series of bus channels produced by this company are applicable for high buildings,industrial factory Convenient, Safe And Reliable
building with many floors, workshops with concentrated lathes and with varied technolotgy, the old workshops rebuilt, In the high buildings, the busbar system and its economic effect is obviously prior to the cable system in the supply
various labs, exhibition halls, gyms, hotels, banks, entertainment and other places,and used for feeding and distributing of power. It's not necessary to design and lay cables for each floor separately. The whole building only needs a single
electricity. It has the characteristics of sagfty & reliability, easy installation, flexible construction, small volume but large bus system for the supply of power. Only after inserting the jack box into the bus system, can it supply the power for
capacity, short cycle for construction, long service life and the like. The concrete technical parameters are as follows: each floor. So it is obviously safer, simpler & easier and reliabler than the cable system.
