Explosion proof type is an explosion-proof type of electrical equipment, whose shell can withstand explosive mixtures entering the interior of the shell through any joint surface or structural gap without damage, and will not cause ignition of explosive gas environments formed by one or more gases or vapors outside.
The explosion-proof shell must have explosion-proof and anti explosion performance. Generally, the shell of explosion-proof products is relatively bulky and suitable for fixed installation and use of products and equipment. The three elements of explosion-proof shell design are the width, gap, and roughness of the explosion-proof joint surface.
The design requirements for the three elements of explosion-proof are also different for different explosive gas environments used in mining Class I, non mining IIA, IIB, and IIC. Specific reference can be made to the design standards of GB/T3836.1 and GB/T3836.2.
Shenzhen Zhongnuo Testing has long been dedicated to the design, testing, and certification services of explosion-proof products. We have a professional team of structural engineers in the field of explosion-proof, familiar with explosion-proof standard requirements and certification processes.
