This standard outlines specifications for explosion-proof variable frequency three-phase asynchronous motors for YAP423 petroleum drilling rigs. It covers type, dimensions, technical requirements, and more, adhering to GB3836.1 and GB3836.3 for explosion-proof ratings (Exell T3, Zone I). The motors meet HSE, have an IP44/IP54 protection level, and use cooling methods IC06 or IC17. Suitable for altitudes up to 1000m and temperatures from -20°C to +40°C, with a relative humidity limit of ≤95% at +45°C.
