Characteristics of High Voltage Explosion-proof Three-Phase Induction Motor YB 560-800 series: This flameproof motor is characterized by a small volume, light weight, little vibration, a low noise, reliable and safe operation and convenient maintenance. Applications of High Voltage Explosion-proof Three-Phase Induction Motor YB 560-800 series: 1)EExd I : This explosion-proof motor we manufactured in China can be used in the underground coal mines where the explosive mixture such as methane or dust exist. 2)EExd II BT4: This flameproof motor is also suitable for sites where the hazardous environment is classified into II Group, B Class, and Temperature T1-T4. Working Conditions of High Voltage Explosion-proof Three-Phase Induction Motor YB 560-800 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 6000V and 10000V and can generate specific voltage; 5) Rated frequency is 50Hz and can also be 60Hz. Its our eternal and changeless pursue to offer you excellent explosion-proof motors!
