Advantages and disadvantages of various models of low-voltage switchgear

GGD type AC low-voltage switchgear: This cabinet has advantages such as reasonable structure, convenient installation and maintenance, good protective performance, high breaking capacity, large capacity, strong dynamic and thermal stability, and wide practicality of electrical solutions. It can be used as a replacement product. Disadvantages: it has few circuits, cannot be arbitrarily combined between units and occupies a large area, and cannot be connected to computers.

GCK cabinet: High sectioning capacity. Good dynamic and thermal stability, advanced and reasonable structure, flexible electrical scheme, strong serializability and versatility. Various scheme units can be combined arbitrarily, and a cabinet can accommodate a large number of circuits, saving land area, high protection level, safe and reliable, and convenient maintenance. Disadvantages: the horizontal busbar is set on the top of the cabinet, and the vertical busbar does not have a flame-retardant plastic functional board, which cannot be connected to the computer.

GCS low-voltage withdrawable switchgear: It has high technical performance indicators, can adapt to the development needs of the power market, and can compete with existing imported products. It is a new type of low-voltage withdrawable switchgear designed based on the principles of safety, economy, rationality, and reliability. It also has high breaking and connecting capacity, high dynamic and thermal stability, flexible electrical schemes, convenient combination, strong practicality, novel structure, and high protection level.

MNS series products: The cabinet body is assembled using C-shaped steel, with a unified appearance, high accuracy, and good drawer interchangeability; The width of the MCC cabinet is only 600mm, and the usage capacity is large, which can accommodate more functional units and save construction land. The components inside the cabinet can be configured with various models of switches according to the different needs of users, better ensuring the high and reliable operation of the product. This device can reserve automation interfaces, and can also install modules on the switchgear to achieve "three remote" functions and control equipment such as remote signaling, telemetry, and remote control. The disadvantage is high cost, There is a certain difficulty for small and medium-sized users.

Advantages of the MNS series main product: compact design, strong versatility with a small space and a large number of functional unit structures, flexible assembly, and the 25mm module C-shaped material can meet the requirements of various structural forms, protection levels, and usage environments. Adopting standard module design, it can form standard units for protection, operation, conversion, control, adjustment, indication, etc. Users can choose to assemble according to their needs.

GGD is a fixed cabinet, GCK, GCS, and MNS is a drawer cabinet

The drawer pushing mechanism of GCK, GCS, and MNS cabinets is different

GCS cabinet can only be used as a single side operation cabinet, with a depth of 800mm

MNS cabinet can be used as a double-sided operation cabinet, with a depth of 1000mm

Overall, withdrawable cabinets save space, are easy to maintain, have multiple outgoing circuits, and are expensive in cost; The fixed type has relatively fewer outgoing circuits and occupies more land. If the customer provides too few locations and cannot make a fixed type, it should be changed to a drawer type.
