Product Introduction
YB2 Series Flameproof Three-Phase Asynchronous Motors
YB2 series flameproof three-phase asynchronous motors feature high efficiency, low noise, minimal vibration, high locked-rotor torque, reliable operation, and aesthetic appearance. They are critical electrical products used in petroleum, chemical, and coal industries. The explosion-proof performance of this series complies with GB3836.1 Electrical Apparatus for Explosive Gas Atmospheres—Part 1: General Requirements and GB3836.2 Electrical Apparatus for Explosive Gas Atmospheres—Part 2: Flameproof Enclosure "d", making them suitable for locations with explosive gas mixtures. Fully conforming to International Electrotechnical Commission (IEC) standards, these motors can be exported to countries and regions implementing IEC norms and installed in imported mechanical equipment.
