YB3 Series Explosion-Proof High Voltage Motors
Description
YB2 Series High-Voltage Flameproof Three-Phase Induction Motors This series is a newly developed product designed by our company through the adoption of advanced technologies and extensive practical experience in manufacturing high-voltage flameproof three-phase induction motors.
The motors feature a cast iron frame, offering advantages such as compact structure, high protection class, and ease of installation and maintenance. Through further optimized design and meticulous manufacturing, they deliver high efficiency, energy savings, reliable performance, low noise, minimal vibration, and long service life. This series is suitable for driving various general mechanical equipment, including fans, compressors, water pumps, machine tools, and conveying machinery. They are widely used as prime movers in industrial and mining sectors such as mining, steel, machinery, petroleum, chemical, and power plants.
The explosion-proof performance of this series complies with:
GB 3836.1-2010 Explosive Atmospheres – Part 1: Equipment – General Requirements
GB 3836.2-2010 Explosive Atmospheres – Part 2: Equipment Protection by Flameproof Enclosure “d”
They are designed as flameproof types with explosion-proof markings: ExdI Mb, ExdIIAT4 Gb, ExdIIBT4 Gb, ExdIICT4 Gb. Suitable for hazardous areas classified as Zone 1 and Zone 2 in explosive gas atmospheres, they are applicable in fixed equipment in underground coal mines and in factory environments with explosive mixtures of Class IIA, IIB, or IIC gases or vapors, with temperature groups T1–T4.
