Enclosed Electrical Switchgear

 

Brief Introduction

 

GCS series enclosed electrical switchgear is suitable for electric energy conversion, distribution and control of power, power distribution, motor control center and capacitance compensation of low-voltage distribution systems such as power plants, substations, petrochemical departments, factories and mines, high-rise buildings, etc.

GCS low-voltage draw out switchgear is based on the requirements of the supervisor of the Ministry of Power, the majority of power users and the design department. In order to meet the needs of the developing power market for capacity expansion, computer interface, centralized power control, convenient installation and maintenance, and shortened accident handling time, a new type of low-voltage draw out switchgear was designed based on the principles of safety, economy, rationality and reliability. The product has the characteristics of high breaking and connecting ability, good dynamic and thermal stability, flexible electrical scheme, convenient combination, strong practicability, novel structure and high protection level.

Operation environment

 

The ambient air temperature is not higher than+40°C and not lower than-5°C. The average temperature within 24 hours shall not be higher than+35°C.

Indoor installation and use, the altitude of the place of use shall not exceed 2000 meters.

The relative humidity of ambient air shall not exceed 50% at the highest temperature of+40°C, and a larger relative temperature is allowed at the lower temperature. (for example, 90% at +20°C) The influence of condensation that may occasionally occur due to temperature change should be considered.

When the equipment is installed, the inclination from the vertical plane shall not exceed 5%.

The equipment should be installed in a place where there is no violent vibration and where the electrical components are not corroded.

 

Users can negotiate with the manufacturer to solve special requirements.
