GGD type AC low-voltage power distribution cabinet is suitable for power users such as power plants, substations, factories and mines, etc. as the AC 50Hz, rated working voltage 380V, rated working current to 4000A power distribution system, as power, lighting and power distribution equipment , distribution and control.
GGD type AC low-voltage power distribution cabinet is a low-voltage power distribution cabinet designed according to the requirements of the Ministry of Energy, the majority of power users and the design department. It has high breaking capacity and good dynamic thermal stability. The electrical scheme is flexible, the combination is convenient, the series is strong, the utility is strong, the structure is novel, and the protection level is high. It can be used as a replacement for low-voltage switchgear.
GD AC low-voltage power distribution cabinet complies with IEC439 "Low-voltage switchgear and control equipment" and GB7251 "Low-voltage switchgear".
Environmental conditions used:
1. The ambient air temperature is not higher than +40 °C, not lower than -5 °C, and the average temperature within 24 hours shall not be higher than +35 °C. The relative humidity of the surrounding air does not exceed 50% at a maximum temperature of +40 ° C, and allows a relatively large relative humidity at a lower temperature; (for example, 90% at +20 ° C), it should be considered due to temperature changes Occasionally the effect of condensation.
2. Installation and use indoors, the altitude of the place of use shall not exceed 2000m.
3. When the equipment is installed, the inclination of the vertical surface should not exceed 5 degrees. The equipment should be installed in places where there is no severe vibration and impact, and where the electrical components are not corroded.
4. When the user has special requirements, it can be resolved by negotiation with the manufacturer.
