An explosion-proof type is a type of explosion-proof design for electrical equipment.
The housing is capable of withstanding explosive mixtures entering the housing through the housing joint surfaces or structural gaps, and exploding internally without being damaged.
And ignite an explosive gas atmosphere formed by one, multiple gases, or vapors.
The explosion-proof housing must possess both explosion-proof and anti-explosion capabilities. Generally, the housing of products designed for explosion-proofing tends to be rather bulky.
Products and equipment suitable for fixed installation and use.
Explosion-proof face width, gap, and roughness are the three key elements of explosion-proof housing design.
Design requirements for explosion-proof three elements vary depending on the different explosive gas environments used in Class I mining, non-mining Class IIA, IIB, and IIC.
Refer to the design standards of GB/T3836.1 and GB/T3836.2 for specifics.
