Devices for power plants, petroleum, chemical, metallurgy, textile, high-rise building distribution systems and other industries, in large power plants, petrochemical and other high degree of automation, computer interface requirements and place, as the three-phase AC frequency is 50 ( 60) Hz, rated voltage of 380V (600V), rated current 4000A and below the hair, power distribution systems, motor centralized control, reactive power compensation using the low voltage power distribution equipment.
This device is designed to meet the following standards: IEC439-1 Low-voltage switchgear and control equipment; GB7251.1 Low-voltage switchgear and control equipment Part; JB/T9661 voltage withdraw-able switchgear.
II Environmental conditions:
- The ambient air temperature is not higher than +40 ºC, not less than -5 ºC. 24 hours, the average temperature not higher than +35 ºC. Over time, the rerating according to the actual operating conditions.
- Indoor use, place of use shall not exceed the altitude of 2000m.
- Relative Humidity: +40 ºCat the highest temperature of less than 50% in the lower temperature allows a greater relative humidity (e.g. 90% at +20 ºC), should also take into account the temperature change could come about by accident condensate the impact of disclosure.
- When installing the unit and the vertical gradient of not more than 5 °, and the entire group of cabinet out relatively flat (consistent with GBJ232-82 standard).
- The device should be installed in the absence of severe vibration and shock, and not enough to place electrical components from corrosion.
- Users with special requirements can be resolved through consultation with the Company.
