Overview
GCK low-voltage draw-out switchgear is suitable for low-voltage distribution system with AC 50Hz and rated working voltage of 380V. It contains the functions of power center (PC) and motor control center (MCC), and all technical parameters meet the national standards. It has the characteristics of perfect structure, beautiful appearance, high electrical performance, high protection level, safety and reliability, and convenient maintenance. It is an ideal distribution device for low-voltage power supply systems in metallurgy, petroleum, chemical industry, electric power, machinery, textile and other industries.
This product conforms to IEC-439 and GB7251.1 standards.
Main feature
◇ GCK1 and GCJ1 are assembled composite structures, and the basic skeleton is assembled by special profiles；
◇ The cabinet frame, part size and opening size change according to the basic modulus E=25mm；
◇ In MCC scheme, the cabinet is divided into five areas (rooms): horizontal bus area, vertical bus area, functional unit area, cable room and neutral grounding bus area. The districts are isolated from each other to ensure the normal operation of the line and effectively prevent the fault from expanding；
◇ Because all the structures of the frame are fastened and connected by screws, the welding deformation and stress are avoided and the accuracy is improved；
◇ Parts have strong universality, good applicability and high standardization.
◇ The extraction and insertion of functional units (drawers) are lever operation, and the operation with rolling bearings is light and reliable.
Use environmental conditions
◇ Altitude above sea level should not exceed 2000M；
◇ Ambient air temperature: -5℃ -+40℃ and the average temperature ≤ +35℃ in 24h；
◇ Air condition: With clean air. Relative humidity should not exceed 50% at+40℃ . Higher relative humidity is allowed at lower temperature. Ex. 90% at+20℃；
◇ Places without fire, explosive danger, serious pollution, chemical corrosion and fierce vibration；
◇ Installation gradient not exceed 5°；
◇ Control center is suitable to the transportation and store with following temperature :-25℃ -+55℃，in short time (within 24h) it should not exceed +70℃ .
