The motor can be manufactured into two explosion-proof types: positive pressure housing type Expx and Expz. The Expx explosion-proof type can be used in Zone 1 and Zone 2, and the Expz explosion-proof type can be used in Zone 2. The two explosion-proof types are used in factories in explosive gas environments formed by gas, steam or mist-like explosive gas with ignition temperatures of groups T1, T2, T3, and T4 and air. The positive pressure housing type Expx can also be used on Class I equipment. This series of motors are made of carefully selected materials and are well made. They have the characteristics of small size, light weight, high power, high efficiency, low noise, low vibration, safe and reliable operation, easy use and maintenance, energy saving and environmental protection, etc.
Application
This series of motors has the characteristics of lower center height, greater power, lower noise, safe and reliable operation, and convenient use and maintenance. It is suitable for driving various ventilators, compressors, water pumps, crushers, cutting machinery, transportation machinery, general machinery and other mechanical equipment, and is used as the original power in various working conditions such as mining, steel, machinery, petroleum, chemical industry, power station, etc. Whether indoors or outdoors, in plateau climate or hot and humid climate, this series of high-voltage three phase ac motors can always provide outstanding driving force and has won the trust and praise of users.
