GGD Type AC Low Voltage Power Distribution Cabinet<\/strong><\/h4>\n

Product Application<\/strong><\/p>\n

The GGD type AC low voltage power distribution cabinet is suitable for power users such as power plants, substations, factories and mining enterprises. It is used in AC 50Hz distribution systems with rated operating voltage of 380V and rated operating current up to 3150A for power conversion, distribution and control of power, lighting and distribution equipment.<\/p>\n

The GGD cabinet was designed according to requirements from the competent energy authority, broad power users and design departments, based on principles of safety, economy, rationality and reliability. It has high breaking capacity, good dynamic and thermal stability, flexible electrical schemes, convenient combination, strong serialization and practicality, novel structure and high protection grade. It is an updated product for low-voltage complete switchgear. It complies with IEC439 Low-Voltage Switchgear and Controlgear and GB7251 Low-Voltage Complete Switchgear standards.<\/p>\n

Use Environment Conditions<\/strong><\/p>\n

    \n
  1. The ambient air temperature shall not be higher than +40C, not lower than -5C, and the 24-hour average temperature shall not be higher than +35C.<\/li>\n
  2. For indoor installation and use, the altitude of the installation site shall not exceed 2000m.<\/li>\n
  3. The relative humidity of the surrounding air shall not exceed 50% at the maximum temperature of +40C. Higher relative humidity is allowed at lower temperatures, for example 90% at +20C. The possible influence of occasional condensation caused by humidity changes shall be considered.<\/li>\n
  4. When installed, the inclination from the vertical plane shall not exceed 5 degrees.<\/li>\n
  5. The device shall be installed in places without severe vibration or impact, and where electrical components will not be corroded.<\/li>\n
  6. If the user has special requirements, they can be negotiated with the company.<\/li>\n<\/ol>\n

    Main Circuit Scheme<\/strong><\/p>\n

    The main circuit of the GGD cabinet is designed with 129 schemes and 298 specifications, excluding derivative schemes and specifications caused by auxiliary circuit function changes and control voltage changes. GGD1 has 49 schemes and 123 specifications; GGD2 has 50 schemes and 107 specifications; GGD3 has 27 schemes and 68 specifications. The main circuit schemes were selected after consulting design and user departments and include schemes required by power plants. Rated current is increased to 3150A, suitable for distribution transformers of 2000kVA and below. In addition, GGJ1 and GGJ2 capacitor compensation cabinets are designed for reactive power compensation, with 4 main circuit schemes and 12 specifications.<\/p>\n
