YB2 explosion-proof motor for coal mine non-mining working space And the hazardous locations has IIA, IIB temperature group T1-T4 group of explosive mixtures exist .
YB2 series flameproof three-phase asynchronous motor (center high 80-335)
1. Overview
YB2 series explosion-proof three-phase asynchronous motor (center high 80-355) is fully enclosed fan-cooled squirrel-cage explosion-proof motor, with high efficiency, energy saving, temperature rise margin, long life, good performance, Explosion-proof structure of advanced, high reliability, easy maintenance and other characteristics.Explosion-proof performance of this series of products in line with GB3836.2-2010 "Explosive environment Part 2: Flameproof shell" d "protection of equipment" and the International electrician Commission standards IEC79-1 were made explosion-proof dI, d Ⅱ AT4, d Ⅱ BT4, applicable In the coal mine non-mining face and the factory has d Ⅱ A, d Ⅱ B level of explosive mixtures exist in dangerous places. The main body enclosure is IP55. This series of motor cooling method for the IC411.
