AI Technical Summary
When the cable core of a fiberglass cable tray is burning, water extinguishing methods pose a significant risk and cannot accurately determine the combustion path, resulting in poor flame retardant performance.
A cutter and pressure bar with a flame-retardant coating were designed, combined with a lifting assembly and a push-pull assembly, to precisely cut off and interrupt the burning process when the cable is burning. The pressure bar is used for local positioning, the cutter coating is used for flame retardancy, and the base is fixed to the cable tray component by locking rods and screws to ensure stability and convenience.
It achieves precise cutting and stable flame retardancy when cables are burning, protecting cables to the greatest extent and improving the ease of use and flame retardant effect of FRP cable trays.
