GCK Low Voltage Withdrawable Switchgear

Overview

GCK LV withdrawable switchgear is applicable to the low voltage distribution system with AC 50Hz,rated working voltage of 380V. It contains power center (PC)and motor control center (MCC)functions. Each technical parameter meets national standards. With  characteristics  of advanced  structure, attractive  appearance, high  electric  performance, high  protection level, reliable and safe, and easy to maintain, it is the ideal distribution device for low voltage power supply systems in metallurgy, petroleum, chemical,  power, machinery  and  light  weaving   industries, etc.

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

Features

+   GCK1 and GCJl are assemble-type combined structures.The basic frameworkis assembled by adopting special bar steel;

+Cabinet framework,component dimension and hole size change according to basic modulus E=25mm;

+In the MCC project,cabinet is divided into five zones (compartments):the horizontal busbar zone,the vertical busbar zone,the function unit zone,the cable compartment,and the neutral earthing busbar zone.Each zone is isolated mutually for the circuit’s normal running and effectively prevents fault expansion;

+All structures of framework are connected and firmed by bolts,so it avoids the welding distortion and stress,and upgrades the precision;

+Components have strong universality,good applicability and high standardization degree;

+Draw-in and draw-out of function unit (drawer)adopts lever operation,which is easy and reliable coupled with rolling bearing.
