Explosion-proof motors are large-scale driving equipment used in petrochemical production equipment. They can be used to drive pumps, fans, compressors, reducers and other transmission machinery in the petrochemical industry. In response to the requirements of the petrochemical industry for explosion-proof motors, Shanghai Dasu Company has developed various types of explosion-proof motors suitable for petrochemical use in accordance with the requirements of the 2nd and 3rd energy efficiency standards in GB18613-2012, which have energy saving, large temperature rise margin, long life, Good performance, low noise, advanced explosion-proof structure, high reliability, convenient use and maintenance, etc. It is widely used in coal mine underground (non-excavation working face) (Exd I) and factories (Exd II AT4, Exd II BT4) containing methane and other gases or coal dust containing combustible gases of Class A and Class B T1~T4 groups or Place where steam and air form an explosive mixture. Rated voltage: 380, 660, 1140, 380/660, 660/1140V, rated frequency 50HZ, power range: 0.12-375kw, insulation class: F, protection class: IP55.
