Summary
As a three-phase AC four-five-wire system, GCK low-voltage withdrawable switchgear is widely used in power plants, metallurgical plants, petrochemical, light industry, textile industry, ports, buildings, hotels and other places. It is 380V, 660V, frequency of 50Hz, power distribution and motor centralized control of power supply system with rated current 5000A and below.
GCK is a comprehensive test and has obtained CCC certification. It is assembled from high-voltage switchgear and is designed to meet the following standards:
Standard GB7251.1-2005 "Low-Voltage Complete Switchgear"
Standard IEC60439.1-1992 "Low-Voltage Switchgear and Control Equipment"
Model and meaning
Conditions of use
By the ambient air temperature is not higher than +40 DEG C, not less than -5 DEG C, within 24 hours, the average temperature is not higher than +35 DEG c;
9:28 relative temperature at the maximum temperature of 40 DEG C does not exceed 50%, which allowed at lower temperature and higher relative humidity, such as 20 DEG C was 90%.
* the air is clean, non corrosive and explosive gas, and can damage the insulation no conductive dust:
It was no shock and vibration occasions, vertical installation, inclination should not be greater than 5 degrees;
The altitude does not exceed 2000 meters;
9:28 switchgear is available in the following temperature transport and storage: 25 DEG to 55 DEG C, in a short period of time (not more than 24 hours) is not more than 70 DEG C;
By the users of these conditions are not met should consult with the manufacturer.
