This series of flameproof motor is the basic series of three phase asynchronous motors,which are fully enclosed ,self-fan cooled,squirrel-cage and flameproof,developed by our company on the basis of referring to the unified design of the industry. Power level,the size of the installation in line with the international electrotechincal commission (IFC)standards,explosion-proof performance conforms to GB3836.1″explosive environment,part1:general requirements for equipment,GB3836.2″ explosive environment part 2:the flame-proof shell “d” protection device”,the GB12476.1-2013 the combustible dust enviroment with electrical equipment part1:general requirements and GB12476.5-2013″combustible dust environment with electrical equipment part5:shell protection type ”tD”‘.Motors with different explosion-proof marks are applicable to places where the representative gas is hydrogen,places where the mixture gas(containing dust)is explosive,and places where the combustibility is dust.
