Switchgear Structure 
Houndreds types product as like GCK low-voltage withdrawable switchgear is the basic frame for the combination of fabricated structure, the frame of the whole structure by screw fastening connection each other into the basic framework, according to the need to add the door again, baffle, baffle plate, a drawer, mounting bracket and busbar and electrical components and other parts, assembled into a complete control center tank, this structure has the following features:
1. The cabinet frame adopts C profile, bolt connection without welding structure so as to avoid welding deformation and stress, and improve the installation accuracy.
2. Internal structure shall be galvanized.After pickling and phosphating, the exterior was sprayed with electrostatic epoxy powder.
3. (PC) in the center of the power distribution ark into line, busbar area across the top level, lower level of busbar area for circuit breaker, the breaker can be configured homebred CW1, HSW1 series, can also according to customer's need to configure the foreign electric company production of various kinds of circuit breaker, such as ABB company E series circuit breaker, as well as intelligent circuit breaker and so on.
