Description

Technical Field

[0002] In the power grid, the distribution cabinet is the hub of the circuit, and its safety is related to the entire circuit. In actual use, the outer shell of the distribution cabinet is mostly made of substrate board. This substrate board will conduct the voltage to the outer shell of the distribution cabinet when the circuit leaks, which often causes electric shock accidents. There are also distribution cabinets made of plastic, but plastic is easy to burn and releases toxic gases to make people faint and then lose their lives. Many people are not burned to death in fires, but killed by toxic gases. In particular, hydrogen chloride released by the burning of plastic is the main cause of many fire deaths. Therefore, it is necessary to find a flame-retardant distribution cabinet that does not release toxic gases. Summary of the invention
