Product details
purpose
GCK low-voltage withdrawable switchgear is widely used in power plants, metallurgical steel rolling, petrochemical industries, light industry and textiles, ports and docks, buildings and hotels, etc., for distribution and centralized motor control in power supply systems with AC three-phase four-wire or five-wire systems, voltages of 380V and 660V, frequencies of 50Hz, and rated currents up to and including 5000A.
GCK is an assembled low-voltage switchgear that has undergone comprehensive type testing and obtained CCC certification. Its design complies with the following standards: the national standard GB7251.1-2005 "Low-Voltage Switchgear Assemblies"
Standard IEC60439.1-1992 "Low-voltage Switchgear and Controlgear Assemblies"
Normal usage conditions
◇ The ambient air temperature should not exceed +40℃ or fall below -5℃, and the average temperature over a 24-hour period should not exceed +35℃;
◇ The relative humidity should not exceed 50% at the upper temperature limit of +40℃, and a higher relative humidity is permissible at lower temperatures, such as 90% at +20℃;
◇ The air is clean, free from corrosive and explosive gases, and devoid of conductive dust or dust capable of damaging insulation:
◇ In situations without significant shaking or impact vibration, when installed vertically, the inclination should not exceed 5 degrees;
◇ Altitude not exceeding 2000 meters;
◇ The switch cabinet is suitable for transportation and storage at the following temperatures: -25℃ to +55℃, with a maximum temperature of +70℃ for a short period of time (no more than 24 hours);
◇ If the user cannot meet the above conditions, they should consult with the manufacturer.
