The GCK(L) low-voltage withdrawable switchgear is suitable for low-voltage power distribution systems with an alternating current of 50Hz and a rated working voltage of 380V. It incorporates the functions of a power center (PC) and an electric motor control center (MCC), and all technical parameters meet national standards. It features an advanced structure, an attractive appearance, high electrical performance, a high level of protection, excellent safety and reliability, and convenient maintenance. It is an ideal power distribution device for low-voltage power supply systems in industries such as metallurgy, petroleum, chemical engineering, power, machinery, and textiles. 

Structure Explanation

The basic frame of GCK(L) is a modular assembly structure. All the structural components of the frame have undergone galvanizing and powder coating treatments. They are connected to each other through screws to form the basic frame. Then, according to the requirements, doors, baffles, drawers, installation brackets, busbars and electrical components, etc. are added to assemble a complete control center cabinet. This product's frame is made of special-shaped steel. It is positioned by angle plates and assembled by connecting with screws. The dimensions of the parts and the opening dimensions are based on the basic modulus of 25 millimeters. The main structure design is a fully assembled structure. 

This switch cabinet fully complies with the national standard GB7251 and the international standard IEC61439-1. 

Main features

GCK(L) is a modular assembly structure. The basic framework is made of special profiles and assembled together. 

The cabinet frame, component dimensions, and opening dimensions change according to the basic modulus, with E = 25mm. 

In the MCC scheme, the distribution cabinet is divided into five areas (rooms): the horizontal busbar area, the vertical busbar area, the functional unit area, the cable room, and the neutral grounding busbar area. These areas are isolated from each other to ensure the normal operation of the lines and effectively prevent the expansion of faults. 

Since all the structures of the framework are firmly connected by screws, it avoids welding deformation and stress, and improves the accuracy. 

The components have strong versatility, good applicability and a high degree of standardization. 

The extraction and insertion of the functional unit (drawer) are operated by levers. The addition of rolling bearings on the guide rails makes the operation both light and reliable.
