GCK Low-voltage withdrawable switchgear

The MNS system is a product introduced by our company based on the manufacturing technology of Swiss ABB company. It is a factory-assembled low-voltage switch cabinet device. The technical standards comply with GB7251.1, IEC439-1, VDE0660 Part 500, BS5486 Part 1, UTE63-410, and as a marine product, it also meets Lloyd's Register's marine standards.

The MNS system's low-voltage switch cabinet includes fixed technology and drawer technology. The selected materials are divided into steel plate structure technology and plastic structure technology. The latter technology level reaches the international level of the 1990s.

The MNS system can meet various power supply and distribution requirements and can be widely used in land-based, power stations, nuclear power plants, marine, oil platforms and other industrial and mining enterprises' power distribution systems.

Operating Conditions

● Compact design: More functional units can be accommodated in a smaller space.

● Strong structural versatility and flexible assembly. C-shaped profiles with a 25mm modulus can meet the requirements of various structural forms, protection levels and usage environments.

● Standard module design: It can be combined to form standard units such as protection, operation, conversion, control, regulation, measurement, indication, etc. Users can choose and assemble them as needed. With over 200 types of assembly components, various cabinet structure schemes and fixed partitions or drawer units can be assembled.

● Safety: A large number of high-strength flame-retardant engineering plastic components are used, effectively enhancing the safety performance.

● High technical performance: Main parameters reach the contemporary international level.

● Compact storage space: High degree of standardization, which can significantly reduce the storage and transportation space for prefabricated components.

● Easy assembly: No special complex tools are required.
