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 protection grade, reliable and safe and easy to maintain.
It 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.
1.GCKI and GCJI 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.
