Brief Introduction of Explosion-proof Three-phase Induction Motor YB2 series:
According to the requirements of < Electrical Apparatus for Explosive Gas Atmosphere Part 1: General Request> and< Electrical Apparatus for Explosive Gas Atmosphere Part 2: Flameproof Enclosure ‘D’> of GB3836.1-2000, this explosion-proof three-phase induction motor YB2 series can be made into flameproof motors. Furthermore, this series of explosion-proof motors has also passed ATEX certifications (only for EExd BT4), and also complied with the Essential Health and Safety Requirements of CENELEC EN 60079-0:2004 and CENELEC EN 60079-1:2004)
Applications of Explosion-proof Three-phase Induction Motor YB2 series:
1)EExd I: This explosion-proof motor we made in China can be used in the underground coal mines where the explosive mixture such as methane or dust exists.
2)EExd II BT4: This explosion-proof motor is suitable for sites where the hazardous environment is classified into II Group, B Class, and Temperature T1-T4.
Working Conditions of Explosion-proof Three-phase Induction Motor YB2 series:
1) Ambient temperature will change according to different seasons, but it should not surpass 35℃ (under coal mine) or 40 ℃ (factory), the lowest ambient temperature should be -15℃;
2) Local altitude should never surpass 1000m;
3) The maximum air relative humidity should be lower than 95% (while temperature keeps at 25℃)(under coal mine) or the monthly maximum mean relative temperature of the most humid month should be 90%, and meanwhile the lowest temperature of this month should not over 25℃ (factory).
4) Rated voltage is 380V and can generate specific voltage;
5) Rated frequency is 50Hz and can also be 60Hz.
