GCK low-voltage withdrawable switchgear
An overview,
And houndreds types product as like GCK low-voltage withdrawable switchgear is original mechanical committee issued in 85 new product development projects. The product organization joint was designed and successfully trial-produced by day pass, and in 88, has presided over by the identification of a prototype of mechanical industry. Each technical parameters have reached the international standard houndreds types product as like GCK, filled the domestic blank, and has been appointed to replace imported products. Houndreds types product as like GCK energy-saving effect is remarkable, the ninth batch of energy-saving products listed by the state. Houndreds types product as like GCK advanced structure, lay and beautiful, high electrical performance, high protection grade, safe and reliable, easy maintenance, is the deposit, oil chemical, electric power, machinery, textile industry such as low voltage power supply system the ideal distribution equipment.
Second, using environmental conditions
