Intensive busway is suitable for AC three-phase four-wire, three-phase five-wire system, frequency 50~60Hz, rated insulation voltage to 690V, rated working current 250~6300A for power supply and distribution system, as industrial and mining, enterprise and high-rise buildings Auxiliary equipment for power distribution equipment, especially suitable for the transformation of workshops and old enterprises.
The dense insulated busway is a compact sandwich structure. The busbar is made of high-quality electrolytic copper with a purity of 99.95% or more. After being treated by tin plating, it is made of high-quality insulating material with good flame retardant and good insulation properties.
The dense busbar housing is also used as a PE wire as a whole, with low reactance, good continuity of protection circuit, safe and reliable energy saving. Its characteristics: good thermal stability, small size, good heat dissipation, low temperature rise, space saving, small pressure drop, reduced energy loss, suitable for high-power current transmission. Dense insulation plugs into the busway. Its moisture and heat dissipation effects are poor. In terms of moisture protection, the busbar is susceptible to moisture and water seepage during construction, resulting in a decrease in phase-to-phase insulation resistance.
The heat dissipation of the dense busbar busbar mainly depends on the outer casing. Due to the compact arrangement between the wires and the wires, the heat energy of the L2 and L3 phases is slowly dissipated, and the temperature rise of the busbar slots is formed to be high. Dense insulated plug-in busbars are limited by the outer panel and can only produce horizontal sections of no more than 3m.
