Fire-resistant bridge with partition

Fire-resistant bridge架Sprayed with a fire-retardant paint on the surface of a standard bridge, it serves as a fire-resistant barrier! In fact, the bridge itself won't catch fire; it's only the cables that could potentially ignite. The fire-retardant principle of the paint...

Fire-resistant bridge trays are protected with a thickness in accordance with JB/T 10216-2000 "Electrical Control and Distribution Equipment."Cable TrayTable 10 specifies that electroplating should be greater than 12μm, hot dipping greater than 65μm, spray painting greater than 50μm, and fire-resistant greater than 500μm, which can be measured with a thickness gauge.
