High voltage flameproof motors Exp refers to our YZYKK & YZYKS series high voltage positively pressurized induction motors. The motors are equipped with a purging and pressurization system. Purging function supplies an enclosure with a protective gas at sufficient flow and positive pressure so as to reduce the concentration of flammable gas or vapor to an acceptable level; Pressurization function supply an enclosure with a protective gas, with or without continuous flow, at sufficient pressure to prevent the entrance of flammable gas, vapor, combustible dust, or ignitable fiber.
They are Expx and Expz, two types of high voltage flameproof motors Exp. Expx type is suitable for zone 1 and zone 2, and Expz for zone 2 only. Expx type can also be used for coal mines.
