SWITCHGEAR

Overview

GGD type AC low-voltage distribution cabinet is suitable for power users such as power plants, substations, factories and mining enterprises, AC
50Hz, rated working voltage 380V, rated working current up to 3150A distribution system, as power, lighting and power distribution equipment, For
distribution and control purposes.
GGD AC low-voltage distribution cabinet is a new type of low-voltage distribution cabinet designed according to the requirements of the superiors
of the Ministry of Energy and the majority of power users and design departments, based on the principles of safety, economy, reasonableness and
reliability. The product has the characteristics of high breaking capacity, good dynamic thermal stability, flexible electrical scheme, convenient combination,
series, practicability, novel structure, high protection level, etc. It can be used as a replacement product for low-voltage switchgear.
GGD AC low-voltage distribution cabinets comply with IEC439 "Low-voltage switchgear and control equipment", GB7251 "Low-voltage switchgear" and
other standards.

Use environment

◆ The ambient air temperature is not higher than + 40℃ , not lower than -5℃ , the average temperature within 24 h shall not be higher than + 35 ℃ ;
◆ Indoor installation and use, the altitude of the place of use shall not exceed 2000m;
◆ The relative humidity of the surrounding air does not exceed 50% at the maximum temperature of +40℃. It should allow a relatively large temperature
at a lower temperature (for example, 90% at +20℃ ). Considering that the temperature may change accidentally. Produce the effects of condensation;
◆ The inclination of the equipment when installed is not more than 5° with the vertical plane;
◆ The equipment should be installed in places where there is no severe vibration and shock, and where it is not enough to corrode electrical
components;
◆ Users can negotiate with the manufacturer if they have special requirements.
