1. Product introduction
GCK low-voltage withdrawable switchgear (hereinafter referred to as switchgear) is suitable for three-phase AC 50 (60) Hz, rated voltage 380V, 660V, rated current 4000A and below three-phase four-wire system and three-phase five-wire power system. It is suitable for power users and power systems in power plants, substations, industrial and mining enterprises, building hotels, airports, terminals, etc. for power distribution and motor control.
2, structural characteristics
2.1 The device is compact and accommodates more functional units in a smaller space.
5.2 Strong versatility and flexible assembly: C-shaped or reinforced C-profiles with a modulus of 25 mm are assembled to meet various structural forms, protection levels and operating environments.
5.3 Adopt standard module design: It can be assembled into standard units such as protection, operation, conversion, control, adjustment, measurement and indication. Users can choose assembly according to their needs to form frame structure and rawer unit of different schemes.
2.4 Safe and reliable: the structural parts inside the cabinet are galvanized and purified, and the door panels and side panels around the cabinet are electrostatically sprayed. Both strong mechanical strength and reliable insulation protection.
2.5 Easy to disassemble: no special complicated tools are needed
