Compared with traditional cables, it shows its advantages when transporting large currents. In addition, because of the selection of new technology applications, new technology and new processes, the junctions of the two sides of the busway and the connection of the branching port are greatly reduced. The contact resistance and temperature at the location, and the application of high-quality insulating materials in the bus duct, which improves the credibility of the bus duct and makes the entire system software more robust.
The busway has good heat dissipation performance. The insulation material of the cable (copper core cable insulation layer and skin insulation layer) is both an insulation material and a heat preservation material. Therefore, when the power engineering cable is laid in the cable tray, the number of layers allowed is more than 2 layers. The heat dissipation is taken into consideration. The busway uses gas transmission to dissipate heat, and releases the heat according to the inseparable steel casing. Therefore, its heat dissipation performance is compared with that of the cable. The heat dissipation performance of the cable can be seen.
Among fire accidents in China, fire accidents caused by electrical equipment accounted for more than 60% of all fire accidents. The perpetrators of fire accidents caused by electrical equipment include: cables, cables, high and low voltage complete sets of equipment, transformers, bus ducts, electrical components, etc., most of which are caused by long-term high temperature and hot, causing the insulation material to become brittle and cause short circuits. Fire accident caused by malfunction.
