What is the proof lights? Explosion-proof Electric Co., Ltd., Zhejiang Koretoyo tell you divided by the type of protection flameproof, increased safety, positive pressure, dust-proof and non-sparking type 5 main types, you can also by other types of protection and the above proof Type or complex combinations of shape and special type. D flameproof equipment could ignite the gas mixture components fried all enclosed in a shell, the shell can withstand any joints or structural shell gaps, penetrate into the interior of the shell flammable mixture in an internal explosion proof lighting without damage shade, and can reduce the time to ensure that the internal gas flames spread through the gap energy of explosion-proof lighting model, not enough to detonate the shell of gas. Explosion-proof lighting. Flameproof the principle according to European standard EN13463-1: 2002 "Non-electrical equipment for explosive atmospheres - Part 1: Basic methods and requirements" concept explosion and fire type, flameproof are allowed to take measures to prevent an internal explosion and fire booster a type of protection is the most commonly used type of protection. Since this type of proof lamp housing is generally used metal materials, heat resistance, high strength and durability shell explosion-proof lighting manufacturers, very popular with users. Moreover, many increased safety explosion-proof lighting components, such as lamp holders, interlock switches, also flameproof structure _ Koretoyo explosion proof light fixture (certified) _ Hebei explosion proof lighting by Zhejiang Electric Co., Ltd. Tianjin Koretoyo act provide office. Zhejiang Koretoyo explosion-proof electrical Ltd. Tianjin Office (#) is Tianjin, explosion-proof lighting leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
