Product Introduction
1. Product Introduction
GGD type AC low-voltage distribution cabinet is suitable for power plants, substations, factories, mines and other power users of AC 50Hz, rated working voltage 380V, rated working current up to 3150A distribution system as power, lighting and power distribution equipment for power conversion, distribution and control.
GGD type AC low-voltage distribution cabinet is a new type of low-voltage distribution cabinet designed according to the requirements of the Ministry of Energy and the majority of power users and the design department, based on the principles of safety, economy, reasonableness and reliability. The product has the features of high breaking capacity, good dynamic and thermal stability, flexible electrical scheme, convenient combination, series, strong practicality, novel structure, protection level, etc. It can be used as the replacement product of low-voltage complete sets of switchgear.
GGD type AC low voltage distribution cabinet conforms to IEC439 ‘Low-voltage complete sets of switchgear and control equipment’, GB 7251 ‘Low-voltage complete sets of switchgear’ and other standards.

2. Operating conditions
>Ambient air temperature not higher than +40°C, not lower than -5°C, average temperature within 24h not higher than +35°C;
>Indoor installation and use, the altitude of the place of use shall not exceed 2000m;
>Relative humidity of the ambient air shall not exceed 50% at a maximum temperature of +40°C, and shall be permitted to be greater at lower temperatures (e.g. 90% at +20°C). Taking into account the effects of condensation that may occasionally occur due to temperature changes;
>The equipment should be installed at an inclination of no more than 5° to the vertical;
>The equipment should be installed in a place free from violent vibrations and shocks and in a place where the electrical components are not sufficiently corroded;
>The equipment should be installed in a place free from vibrations and shocks and in a place that is not sufficiently corrosive.

3. Technical Parameters
4.External Dimension Drawing
When ordering, the user should provide:
Main circuit distribution system diagram and layout plan, rated operating voltage, rated operating current, protection device setting current and the necessary technical parameters.
Specification of inlet and outlet cables.
Model, specification and quantity of main electrical components in the switchgear cabinet.
If the switchgear cabinet or the incoming cabinet needs bus bridge or bus duct, it should indicate the span, the height from the ground and other specific requirements of the data.
When the switchgear is used in special environmental conditions, it should be explained in detail when ordering.
Switchgear surface colour and other specific requirements.
