GGD Low-Voltage Switchgear

Overview

The GGD type AC low-voltage distribution cabinet is suitable for the AC 50Hz, rated working voltage 380V, and rated working current up to 3150A distribution system of power users such as power plants, substations, and industrial and mining enterprises. It is used for the conversion, distribution and control of electric energy for power, lighting and distribution equipment.

The GGD type AC low-voltage distribution cabinet is a new type of low-voltage distribution cabinet designed in accordance with the requirements of the superior authorities of the Ministry of Energy, the majority of power users and design departments, adhering to the principles of safety, economy, rationality and reliability. The product features high breaking capacity, good dynamic and thermal stability, flexible electrical schemes, convenient combination, strong series and practicality, novel structure and high protection level. It can be used as an updated product for low-voltage switchgear assemblies. The GGD type AC low-voltage distribution cabinet complies with standards such as IEC439 “Low-voltage Switchgear and Controlgear Assemblies” and GB7251 “Low-voltage Switchgear Assemblies”.

Usage environment

1. The ambient air temperature shall not exceed +40℃ and shall not be lower than -5℃. The average temperature within 24 hours shall not exceed +35℃.
2. For indoor installation and use, the altitude of the installation site must not exceed 2000m.
3. The relative humidity of the surrounding air shall not exceed 50% when the maximum temperature is +40℃. A higher relative humidity is allowed at lower temperatures (for example, 90% at +20℃), taking into account the possible impact of occasional condensation due to temperature changes.
4. The inclination of the equipment during installation to the vertical plane shall not exceed 5°.
5. The equipment should be installed in a place free from severe vibration and shock, as well as where the electrical components will not be corroded.
6. When users have special requirements, they can negotiate with the manufacturer for a solution.
