GGD AC low voltage switchgear use

The GGD type AC G low voltage switchboard is suitable for the 50Hz of power users such as power plants, substations, factories and mining enterprises, and the distribution system with rated working voltage of 380V and rated current to 3150A as the power conversion, distribution and control of power, lighting and distribution equipment.  

The GGD type G low voltage switchgear is a new low voltage switchboard designed according to the requirements of the Department of energy and the power users and the design department. It is designed in a safe, economic, reasonable and reliable principle. The product has the characteristics of high breaking capacity, good dynamic and thermal stability, flexible electrical scheme, convenient combination, seriation, practicability, novel structure and high protection grade. It can be used as a replacement product for low-voltage switchgear.  

GGD type G low voltage switchgear is in line with IEC 349 "low voltage switchgear and control equipment", GB 2751 "low voltage switchgear" and other standards.

Conditions of use

The ambient air temperature is not higher than +40 C, not less than -5 C, and the average temperature in 24h is not higher than +35 C.

Indoor installation and use. The elevation of the site should not exceed 2000m.

The ambient air relative humidity does not exceed 50% at Zui high temperature of +40 C, and a relatively large relative temperature should be allowed at lower temperature (for example, +20 at 90%).

When the equipment is installed, the inclination of the vertical plane is not more than 5 degrees.

Equipment should be installed in areas where there is no severe vibration and impact and places where electrical components are not sufficiently corroded.

When customers have special requirements, they can negotiate with manufacturers.
