Q: What types of explosion-proof lights are there?
A:
Class I electrical equipment is used in coal mine gas environment. Type I explosion-proof type considers methane and pulverized coal ignition and physical protection measures for underground equipment. When used in coal mine electrical equipment, when its environment can contain explosive gases in addition to methane, it should comply with the corresponding flammable gas requirements of Class I and Class II. Such electrical equipment should be marked with the corresponding marks (for example: Ex d I/IIB T3
Class II electrical equipment is used in explosive gas environments other than coal mine methane gas. Class II electrical equipment is reclassified according to the type of explosive environment it is intended to use, and Class II electrical equipment is reclassified; Class IIA: representative gas propane; Class IIB: Representative gas ethylene; Class IIC: representative gas hydrogen.
Class III electrical equipment is used in explosive dust environments other than coal mines. Class III electrical equipment is reclassified according to the characteristics of the explosive dust environment it is intended to use: Class III electrical equipment Reclassification: Class IIIA: flammable flying flakes; Class IIIB: non-conductive Dust; Class IIIC: Conductive dust.
The explosion-proof explosion-proof lamp produced by Songbei Explosion-proof Electrical Appliances is made of aluminum alloy die-casting with high strength; the surface is high-voltage electrostatic spraying, which has strong corrosion resistance and light structure. Suitable for various installation methods.
