Other metal parts must have anti-corrosion ability, otherwise, anti-corrosion measures must be taken for treatment. All insulation used in power distribution cabinets must be self-extinguishing materials.
The shell of the distribution box with three-proof function is made of engineering plastics, and the color is generally black. Small circuit breakers are installed inside. The size of the box is mainly determined according to the components installed inside. Its sealing performance is very good. It has good waterproof and dustproof functions, and is mainly suitable for places with high corrosion strength and easy water ingress such as chemical plants.
