Brief instruction:

GCK low-voltage extraction switchgear(GCK lv panel) is widely used in power plants, metallurgical steel rolling, petrochemical, light textile, 

port terminals, buildings, hotels and other places as AC three-phase four

For distribution and centralized control of electric motors in power supply systems with voltage 380V, 660V,

 frequency 50Hz and rated current 5000A or below.

Basic info of lv panel:

GCK Overview

GCK LV withdrawable switchgear cabinetis applicable to the low voltage distribution system with AC50Hz, 

rated working voltage 380V. It contains power center(PC)and motor control center(MCC)functions. 

Each technical parameter all reaches national standards. With characteristics of advanced structure,

beautiful appearance,high electric performance, high protect-ion grade, reliable and safe and easy to maintain.

lt is the ideal distribution device for low voltage power supply system in metallurgy, petroleum,chemical,power, 

machinery and light weaving industries etc.

The product accords with standards IEC-439,GB7251.1

GCK Design feature

1.GCK1 and REGCJ1 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 firmed 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.
