The CYCMC37T-NH fire-resistant busway is designed for low-voltage power distribution systems with a rated voltage below 690V, a rated operating current of 250–5000A, and a frequency of 50–60Hz. It is engineered to maintain stable electrical performance and circuit integrity under fire conditions, ensuring reliable power transmission in critical applications.
After years of testing and long-term industrial energized operation, the CYCMC37T-NH fire-resistant busway has demonstrated excellent electrical performance, fire resistance, and mechanical strength, reaching advanced domestic technical standards. Its robust structure and high-temperature-resistant insulation system make it suitable for installations where fire safety and continuous power supply are essential.
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.
