Product features
■ The shell is made of high-strength alloy aluminum by one-time die casting, and the surface is cleaned by high-speed shot blasting and then sprayed with high-voltage electrostatic plastic. The shell has compact and reasonable structure, high material density, good strength, excellent explosion-proof performance, strong adhesion of plastic powder on the surface, good corrosion resistance, smooth surface and elegant appearance;
■ Wiring cavity and main cavity are independent respectively;
■ Steel pipes, explosion-proof flexible pipes, explosion-proof cables and wiring can be used.
