适用范围

Applicable scope

母线槽可为交流三相线、三相四线、三相五线，频率50Hz(或60Hz)额定工作电压660V，额定工作电流为100-5000A，产品具有体积小，输送电流大，安全可靠，安装灵活配电施工互不干扰，设计合理，规格齐全等优点。是现代大、中型企业高层建筑引进工程实验基地等场所最理想的供配设备。带插口的母线槽，可通过插接开关箱能很方便地引出电源分路。母线槽的安装可直接从变压器接到配电柜，也可以从低压柜直接接到配电系统作为配电干线路。CMC密集耐火母线槽、BMC空气耐火母线槽产品主要适用于化工、冶金、文化、体育场馆、展览馆、博物馆、机场、车站等社会公共场所及高层建筑的输配电及消防系统的共用。在正常情况下（非火灾情况）可降容供电：火灾情况下，切断正常供电系统，按额定电流进行消防供电，从而达到正常、消防供电两者兼用，降低成本。

Bus duct can be divided into AC three-phase line, three-phase four-wire, three-phase five-line, with 50Hz (or 6Hz) rated working voltage 660V, rated working current 100-5000A. The product has such advantages as small size, large transport current, safety and reliability, flexible installation, no interference with power distribution and construction, reasonable design and complete specifications, etc., which is the most desirable power supply and distribution equipment to introduce engineering experimental base and other sites for high-rise buildings of modern large and medium-sized enterprises. The installation of bus duct can be directly connected to power distribution cabinet from the transformer, and also can be connected to power distribution system from the low voltage cabinet to function as power distribution main line circuit. CMC intensive fireproof bus duct and BMC air fireproof bus duct products are mainly applicable to the power transmission and distribution and common use of fire-extinguishing system in chemical industry, metallurgy, culture, stadiums and gymnasiums, exhibition halls, museums, airports, stations and other social public places and high-rise buildings. Under normal circumstance (non-fire conditions), it can reduce capacity to supply power: in case of fire, cut off the normal power supply system, and fire protection and power supply should be conducted according to the rated current to achieve the combination of both normal and fire protection power supply, and reduce the cost.
