Flameproof explosion-proof lamps and explosion-proof ballasts are manufactured in aluminum alloy die-cast. The surface of the bodies is sprayed epoxy resin powder, therefore they have good anti-corrosion performance so as to satisfy the requirements in chemical, petrochemical and sea industries. Flameproof explosion-proof lamps comprise aluminum alloy bodies, reflectors, toughened glass transparent parts and guards. Spigot joints are adopted so as to have the functions of opening covers quickly. Flameproof explosion-proof floodlight lamps are used for large range illuminating in the circuits of AC 220V, 50Hz. Mercury vapor lamps, high pressure sodium vapor lamps, metal halide lamps are fitted with explosion-proof ballasts.
