Common types of low-voltage switchgear

The models of low-voltage switchgear are GCD, GCS, GCK and other different models. The GCD type is a low-voltage fixed switch cabinet designed uniformly in the 1990s in China. The cabinet is equipped with advanced ME type or DZ20 type and other types of low-voltage circuit breakers and rotary operation knife switches. GCS and GCK types are low-voltage withdrawable types. Switchgear.

GGD AC low voltage switchgear

The GGD AC low-voltage power distribution cabinet mainly adopts the design form of a general-purpose cabinet. The switch cabinet designer introduced that its structure is mainly assembled by cold-formed rigid welding. This switchgear is designed with full consideration of heat dissipation. There are different numbers of heat dissipation slots on the upper and lower ends of the cabinet. The door and the frame are connected by hinges, which is very easy to install or disassemble.

GCS low voltage withdrawable switchgear

GCS low-voltage withdrawable switchgear is mainly composed of power receiving cabinet, power feeder cabinet, control cabinet, etc. Each functional unit of the cabinet body is separately isolated from the cable room. The switch cabinet designer introduced that its biggest feature is the drawer panel, which has obvious marks such as opening, closing and drawing out, and the drawer unit is equipped with a mechanical interlocking device. This switchgear is mainly used in power distribution systems such as power plants, petroleum, chemical, metallurgy, etc.

GCK low voltage withdrawable switchgear

GCK low-voltage withdrawable switchgear is made of C-profile. Frame parts and special accessories are standard. The unit height of the drawer is 200mm. Each switchgear can install up to nine drawers. The operating mechanism and the drawer are mechanically interlocked. The switch cannot be withdrawn when it is in the closed position. The switchgear designer introduced that it is mainly suitable for the largest working power distribution system of AC 400V, 690V, and its role in the power conversion, distribution and control of power distribution, motor control and lighting power distribution equipment.

MNS combined low voltage switchgear

MNS combined low-voltage switchgear is mainly suitable for all places where power generation, distribution, and electric power are used, mainly in low-voltage systems below 5000A. It has very high flexibility and can be mixed flexibly according to different needs and environments.

The above is an introduction to the performance and characteristics of four common low-voltage switchgear. It can be seen that each switchgear has its own different design features and functional advantages, and also reflects the importance of switchgear design to the entire power distribution system.
