This series of motors complies with the national standards GB3836.1-2010 "Explosive atmospheres Part 1: General requirements for equipment" and GB3836.2-2010 "Explosive atmospheres Part 2: Provisions for equipment protected by flameproof enclosures "d"". At the same time, the design of its flameproof structure and parameters refers to the IEC60079-1 "Structure and test of flameproof enclosures for electrical equipment" and EN50018 "Electrical equipment for explosive atmospheres "d"". The motor is made into flameproof type, and the explosion-proof marks are Exd I Mb, Exd II A T4 Gb, Exd II B T4 Gb. Exd II C T4 Gb, which are respectively suitable for underground fixed equipment in coal mines and factories with Class II A, Class II B, Class II C, and temperature groups T1~T4 where there are explosive gas mixtures.
It is in accordance with IEC standard, and can be exported to the countries and areas that carry out IEC stardard, as well as applied to imported equipment.
From the product design to the delivery of products, follow the ISO9001 quality certification system, strict compliance with quality procedures.
