TQNHMC Refractory Busbar

Fire-resistant busbar trunking consists of a shell coated with fire-retardant paint, busbars wrapped with fire-resistant mica tape, and a support made of fire-resistant insulating material. The support has multiple recesses, into which current bars are embedded and secured. A busbar junction box is located at one end of the fire-resistant busbar trunking, and another is inside the trunking. The fire-resistant busbar trunking has excellent insulation performance and can be used continuously under normal conditions and for more than 1 hour under fire conditions. It can be used in high-rise buildings and important facilities as a replacement for fire-resistant power cables used in power transmission and distribution.
