YB series high voltage explosion proof motor(H355~710mm)

YB355-710 series high voltage flameproof three-phase asynchronous motor is a self-fan-cooled squirrel cage motor with international advanced level designed by our company. Adopting advanced design concepts, it has absorbed advanced technologies in the design of such motors at home and abroad. It has the advantages of small size, light weight, high power, high efficiency, large temperature rise margin, good performance, low vibration and movement, low noise, excellent explosion-proof performance, and high reliability. .
      YB355-710 series high-voltage flameproof three-phase asynchronous motor adopts China"s latest national standards and the International Electrotechnical Commission IEC standard, power range from 160kW ~ 1600kW. YB355-450 series high-voltage flameproof three-phase asynchronous motors comply with GB755 "Rating Electric Motor "Performance", according to GB 3836.1-2010 "Explosive environment Part 1: General requirements for equipment", GB 3836.2-2010 "Explosive environment Part 2: Equipment protected by flameproof enclosure" d "" made of flameproof type. , The explosion-proof marks are ExdI Mb, ExdIIAT4 Gb, ExdIIBT4 Gb, ExdIICT4 Gb. , Suitable for hazardous locations in Zone 1 and Zone 2 with explosive gas atmosphere.
      ExdI Mb is suitable for explosive gas environment in non-excavation face of coal mine with methane or coal dust.
      ExdIIAT4 Gb is suitable for explosive gas atmospheres in factory class II, Class A, with temperature groups T1, T2, T3 and T4.
      ExdIIBT4 Gb is suitable for explosive gas atmospheres of Class II, Class B, and temperature groups of T1, T2, T3, and T4 for factories.
      ExdIICT4 Gb is suitable for explosive gas atmospheres of Class II Class C for factories and temperature groups of T1, T2, T3 and T4.
       The protection grade of the motor body shell and the junction box is IP54, and it can also be made into IP55. On this basis, there are outdoor (W), wet tropical (TH), outdoor wet tropical (THW), indoor anti-corrosion type (F1), indoor anti-corrosion type (F2), outdoor anti-medium corrosion type ( WF1), outdoor anti-corrosion (WF2), the performance index and installation dimensions of the derived three-phase asynchronous motor are the same as those of the basic series.
