Our organization successfully attained IS9001 Certification and European CE Certification of Low Loss 3 Phase Distribution Transformer, Gas Insulated Ring Main Unit, SF6 gas insulated switchgaer. We usually think and practice corresponding for the change of circumstance, and grow up. We firmly believe in that the essence of innovative spirit is to create differentiated value. Communication and execution, team innovation, satisfaction and win-win are our business philosophy and purpose.

GCK Low-voltage metal-enclosed switchgear is a fully assembled combined structure, and all the structures of the cabinet frame are connected by screws, which avoids welding deformation and stress, improves the accuracy, and has a high degree of standardization. It has the characteristics of simple operation, small operating force, safe use, convenient maintenance, stable quality and reliability.

Low-voltage withdrawable switchgear:

Main technical parameters: Rated insulation voltage: 660V, 1000V; Rated working voltage: 380V, 660V; Auxiliary circuit rated voltage: AC 220V, 380V, DC 110V, 220V; Operating frequency: 50Hz~(60)Hz; Rated Current: horizontal bus ≤ 3150A; vertical bus 630A, 800A, 1200A rated short-time withstand current: 50, 80KA/1s neutral bus 30KA/1s; rated peak current: 105KA/0.1s, 176KA/0.1s; functional unit ( Drawer) breaking capacity: 50KA (effective value). Shell protection grade: IP30, IP40; bus setting: three-phase four-wire system, three-phase five-wire system. Operation mode: local, remote, automatic.

Structural features:

The basic cabinet frame of GCK and GCL is a combined assembly structure and adopts standard module design: compact structure and flexible assembly. They can be assembled into standard units such as protection, conversion, measurement and control, and indication. They can be assembled as needed to form different solutions. Frame structure and drawer unit. The cabinet structure has high technical performance, and the main parameters have reached the international advanced level in the 1990s.
