The fire-resistant busway is suitable for power distribution systems with a rated voltage of below 690V, a rated operating current of 250 - 5000A, and a frequency of 50 - 60Hz. After years of testing and industrial energized operation, its electrical properties, fire resistance, and metal structure have reached the domestic level.
Conductor and Lap Joint Conductor in the Busway：The conductors inside the busway and the lap joint conductors are made of T2 electrolytic copper. They are rolled into TMY hard-drawn copper busbars. The purity of the copper reaches over 99.9%, the conductivity is above 97%, and the resistivity is ≤ 0.017777 Ω·mm²/m.
Insulating Materials: All insulating materials are high-temperature resistant insulating materials with a temperature resistance of over 950 °C.
Shell and Side Plates of the Busway System: The shell and side plates of the busway system are made of steel. A fire-resistant coating should be applied to the surface.
Insulation of Copper Conductors in the Busway: The insulation of the copper conductors in the busway is achieved by winding polyesterimide and high-temperature resistant mica tape.
