Product Overview
The GGD type AC low-voltage distribution cabinet is suitable for AC 50Hz, rated working voltage of 380V, and rated working current up to 3150A distribution systems for power plants, substations, factories, mines, and other power users. It is used for power conversion, distribution, and control of electrical energy for power, lighting, and distribution equipment.

Working Conditions

The ambient air temperature shall not exceed 40°C,not be lower than -5°C, and the average temperature within 24 hours shall not exceed+35°℃;
For indoor installation and use, the altitude of the usage location shall not exceed 2000m
The relative humidity of the surrounding air should not exceed 50% at a maximum temperature of+40°C, and a higher relative humidity should be allowed at lower temperatures (such as 90% at+20°C), taking into account the possible impact of condensation caused by temperature changes;
The incination angle between the equipment installation and the vertical plane shall not exceed 5°;
The equipment should be installed in places without severe vibration and impact, as well as in places where electrical components are not susceptible to corrosion;
When users have special requirements, they can negotiate with the manufacturer to resolve them.
