Explosion-proof Three-phase Induction Motor

Product Description

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 GB***6.*****0, 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 ******0:***4 and CENELEC EN ******1:***4) 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 T*-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 *5℃ (under coal mine) or *0 ℃ (factory), the lowest ambient temperature should be **5℃; 2) Local altitude should never surpass ***0m; 3) The maximum air relative humidity should be lower than *5% (while temperature keeps at *5℃)(under coal mine) or the monthly maximum mean relative temperature of the most humid month should be *0%, and meanwhile the lowest temperature of this month should not over *5℃ (factory). 4) Rated voltage is **0V and can generate specific voltage; 5) Rated frequency is *0Hz and can also be *0Hz.
