YB2 ranges of three-phase induction motors are flame-proof motors obtained by renewal and generation-changing of YB ranges of motors. The performances of the products have come up to advanced international standards.
The motors have the advantages of higher efficiency, energy saving, higher locked-rotor torque, lower noise, smaller vibration, safe and reliable operation and beautiful appearance, etc. The outputs, mounting dimensions and their corresponding relationships comply with IEC standards.
YB2 series electric motors are designed and manufactured into
explosion proof type and the explosion proof property conforms to
China National Standards: GB3836.1-2000 Electrical Apparatus for
Explosive Gas Atmospheres-General Requirements. GB3836.2-2000
Electrical Apparatus for Explosive Gas Atmospheres- Explosion proof
Enclosure d and standards IEC79-1, BS4683 and EN50018.
ExdI- safe for use in the non-mining surfaces of underground coal
mines where the explosive mixtures of methane or coal-dust are
present.
ExdIIAT4 - safe for use in plants where the explosive mixtures of
IIA Class, TI, T2, T3 or T4 are present.
ExdIIBT4 - safe for use in plants where the explosive mixtures of
IIB Class, TI, T2, T3 or T4 are present.
ExdIICT4 - safe for use in plants where the explosive mixtures of
IIC Class, TI, T2, T3 or T4 are present.
