3, explosion-proof equipment category - divided into two categories, I for underground coal mining equipment, II for the factory electrical equipment;
4, explosion-proof level - divided into A, B, C three, indicating the strength of its explosion-proof ability;
Example: If the electrical equipment is type IIA flameproof T3 group, the mark is ExdIIAT3; if the electrical equipment is type IIB positive pressure, the temperature group is T6 group, the mark is ExpIIBT6; if the electrical equipment uses more than one compound type, The main type of explosion protection is marked first, followed by other types of explosion protection. For example, the main body uses intrinsically safe type IIC flameproof components, the temperature group is T4, and the mark is ExidIICT4; if the main components are flameproof type IIC, the T4 group The rest of the components are in safety type, and the explosion-proof mark is ExdiIICT4.
