The product services in the power system of generation and supply of rated voltage of 380 V (400), (600), rated current of 4000 A, below three-phase AC, frequency of 50 (60) Hz, and the following of, the electricity supply system of distribution, motor centralized control and reactive power compensation. The product meets the standards of GB7251 JB/T9661 and IEC60439-1.      main distribution panel  

III Service conditions of GCS switchgear

Normal service conditions of switchgear as follows: 

Ambient temperature:

Maximum

+40°C

Maximum 24 hour average

+35°C

Minimum (according to minus 15 indoor classes)

-15°C

Ambient humidity:

Daily average relative humidity

less than 95%

Monthly average relative humidity

less than 90%

Height above sea level at site

less than 1000m

Earthquake intensity 

less than 8 degree

Height above sea level

less than 2000m

This product should not be used under conditions of fire, explosion, earthquake and chemical corrosion environments. 

Special service conditions 

Each special service condition should be proposed in advance and confirmed by the manufacturer and user.

The dielectric strength of the air will be reduced in when altitude is over 1000m at site.

If the ambient temperature is over the maximum degree, the capacity of the using current must be lower than the designed current’s for both main bus bar and branching bus bar. The installation of aerator is propitious to reduce heat.
