Cast aluminum explosion-proof distribution box is an electrical equipment specifically designed for use in potentially explosive environments, with the main purpose of protecting internal electrical components (such as circuit breakers, relays, contactors, etc.) from the effects of fire or explosion caused by explosive gases or dust. This type of distribution box is made of cast aluminum alloy material, which has the advantages of light weight, high strength, and corrosion resistance. The surface is usually treated with electrostatic spraying to further enhance its corrosion resistance and appearance quality.
