GCK Draw-Out Low Voltage Switchgear Electrical Cabinet
Main features
1. GCK1 and GCJ1 are assembled composite structures and the basic skeleton is assembled by special profiles.
2. The cabinet frame. part size and opening size change according to the basic modulus E=25mm.
3. In MCC scheme, he cabinet is diveded into five areas, horizontal bus area, vertical bus area, function unit area, cable room and neutral grounding bus area, the districts are isolated from each other to ensure the normal operation of line and effectively prevent the fault from expanding.
4. 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.
5. Parts have strong universality, good applicability and high standardization.
6. The extraction and insertion of functional unit are lever operation and the operation with rolling bearings is light and reliable .
Use environmental conditions
1. Ambient air temperature: -5~+40 and the average temperature should not exceed +35 in 24h.
2. Install and use indoors. Altitude above sea level for operation site should not exceed 2000M.
3. Relative humidity should not exceed 50% at max temperature +40. Higher relative humidity is allowed at lower temperature. Ex. 90% at +20. But in view of the temperature change, it is possible that moderate dews will produce casually.
4. Installation gradient not exceed 5.
5. Install in the places without fierce vibration and shock and the sites insufficient to erode the electrical components.
6. Any specific requirement, consult with manufactory.
