GCS Main feature

1.Main framework adopts 8MF bar steel.Both sides of bar steel isinstalled with 

9.2mm mounting hole with modulus 20mm and100mm. Inner installation is flexible and easy.

2.Two types of assembly form design for main framework,

full assembly structure and partial (side frame and cross rail) welding structure for user selection.

3.Each function compartment of device is separated mutually

The compartments are divided into function unit compartment, bus

bar compartment and cable compartment.

Each one hasrelative independent function

4. Horizontal bus bar adopts cabinet back level placed array pattern 

for enhancing the capacity of resisting electrodynamic force for bus bar. 

It is the basic measure for obtaininghighshort circuitstrength capacity for main circuit.

5.Cable compartment design makes cable outlet and inlet up and down convenient.

GCS Use environmental conditions

1.Ambient air temperature:-5℃~+40C and the average temperature should not exceed +35°C in 24h.

2. Relative humidity should not exceed 50% at max temperature.

Higher relative humidity is allowed at lower temperature. Ex.90% at+20℃.

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. Installation gradient not exceed 5°

5. Indoor without dust, corrosive gas and rain water attack.
