一种防水耐火柔性母线槽
By using fireproof blocks composed of alumina substrate and aluminum silicate fiber in the bus trunking, the problem of uneven fixation caused by the softness of glass fiber is solved, achieving uniform current transmission and improved fireproof effect. At the same time, the use of heat sink and fan design ensures stable operation of the bus trunking in the event of a fire.

AI Technical Summary
The fiberglass inside the busbar trunking is soft and difficult to install, resulting in uneven stress at the connection between the conductor and the aluminum profile, which affects the current.
The fireproof module, composed of an alumina substrate and aluminum silicate fiber, combined with connectors, heat sinks and fan design, ensures uniform current transmission and improves fireproof performance.
It achieves uniform current transmission, enhances the fire resistance of the busbar trunking, and maintains the busbar trunking within a suitable temperature range through the design of heat sinks and fans, ensuring a stable and reliable power supply.
