GCS Low Voltage Electrical Motor Control Centre MCC Switchgear Panel
Ⅰ.Application
GCS low-voltage withdrawable main distribution panel assembled from modular components from a combination of low-voltage switchgear withdraw-able type. This device is suitable for power plants, transformer substation, petrochemical, metallurgy, steel rolling, light industry and textile factories and enterprises, and residential quarters, high-rise buildings and other places.
Ⅱ.Environmental conditions
1. Ambient air temperature: -5ºC+40ºC and the average temperature should not exceed +35ºC in 24h.
2. Air condition: With clean air. Relative humidity should not exceed 50% at +40ºC. Higher relative humidity is allowed at lower temperature. Ex. 90% at +20ºC.
But in view of the temperature change, it is possible that moderate dews will produce casually.
3. Altitude above sea level should not exceed 2000M.
4. The device is suitable to the transportation and store with following temperature:-25ºC ~+55ºC, in short time (within 24h) it reaches +70ºC.
Under the limiting temperature, device should not suffer damage that can[1]t recover, and it can works normally under normal conditions.
5. If the above operating conditions not meet user's demand. Consult with manufacturer.
6. Technical agreement should be signed additionally if the device is used for marine petrol drill taken platform and nuclear power station.
