Low Voltage Distribution Cabinet
GCK low-voltage withdrawable switchgear set of switchgear is suitable for low-voltage power distribution system with AC 50Hz and rated working voltage 380V. It contains the functions of power center (PC) and motor control center (MCC), and all technical parameters have reached the national standard, featuring advanced structure, beautiful appearance, high electrical performance, high protection level, safety and reliability, and convenient maintenance, etc. It is an ideal distribution device for low-voltage power supply system in the industries of goldsmithing, petroleum, chemical industry, electric power, machinery, and textile.
This product complies with IEC-439, GB7251.1 standard.
1. GCK1andGCJ1are assembled combination structure, the basic skeleton is made of specialized profiles and assembled.
2. The cabinet skeleton, part dimensions and opening dimensions are varied according to the basic module E=25mm.
3. In the MCC program, the cabinet is divided into five areas (rooms): horizontal busbar area, vertical busbar area, functional unit area, cable room, neutral ground busbar area. Each area is isolated from each other to ensure the normal operation of the line to effectively prevent the expansion of the fault.
4. Since all structures of the frame are connected by screws, welding distortion and stress are avoided and accuracy is improved.
5. The parts are universal, applicable and highly standardized.
6. Functional unit (drawer) extraction, insertion for the lever operation, coupled with the configuration of rolling bearings to operate lightweight, reliable.
1. The altitude shall not exceed 2000 meters.
2. The ambient air temperature shall not exceed+40℃, not be lower than-5℃, and the average temperature within 24 hours shall not exceed+35℃.
3. Atmospheric conditions: The air is clean, and the relative humidity does not exceed 50% at a temperature of+40℃. Higher relative humidity is allowed at lower temperatures, For example, it is 90%at+20℃.
4. Places without fire, explosion hazards, severe pollution, chemical corrosion, and severe vibration.
5. The inclination to the vertical plane shall not exceed 5°.
6. The control center is suitable for transportation and storage processes at temperatures ranging from -25℃ to +55℃, and within a short period of time (not exceeding 24 hours) not exceeding+70℃.
