GCK Design feature

1.GCK1 and REGCl are assemble type combined structure. The basic skeleton is assembled by adopting special bar steel.

2.Cabinet skeleton, component dimension and starter size change according to basic modulus E=25mm.

3.In MCC project,parts in cabinet are divided into five zones (compartment): horizontal bus bar zone, vertical bus bar zone, function unit zone, cable compartment, and neutral earthing bus bar zone.Each zone is separated mutually for circuit's normal running and effectively preventing fault expansion.

4.As all structures of framework are connected and fixed by bolts,so it avoids the welding distortion and stress, and upgrades the precision.

5.Strong general performance, well applicability and high standardization degree for components.

6.Draw-out and insert of function unit (drawer) is lever operation, which is easy and reliable with rolling bearing.

Use of conditions:

1. Operating conditions: indoor
2. Altitude: It: 2000m
3. The earthquake intensity is not more than 8 degrees
4, upper limit of ambient air temperature: +40℃
5.Upper limit of average temperature for 24 hours: +35℃
6. the lower limit of ambient air temperature :-5℃
7. the relative humidity of the surrounding environment at +40℃ is 50%
8. no fire, explosion danger, serious pollution and enough to corrode metaland damage the insulation of gas and other bad places
9.No violent vibration, jolting place

Technical Parameters:

No.
