Product features

The GCK low-voltage withdrawable switchgear is a typical isolated withdrawable cabinet equipment. The cabinet is divided into different functional compartments by electroplating plates inside, and each circuit component is uniformly installed in indoor drawers. The drawer height varies with a modulus of 80mm according to functional needs, and drawers with the same width, height, and function can be interchanged.

This series of products has the advantages of high breaking capacity, good dynamic and thermal stability performance, advanced and reasonable structure, practical electrical solutions, strong series and universality, arbitrary combination of various scheme units, multiple circuits accommodated in each cabinet, saving land area, beautiful appearance, high protection level, safety and reliability, and convenient maintenance. It is a popular product of low-voltage complete switchgear in China.
