50-60Hz GGD Low Voltage Switchgear

GGD low voltage distribution switchgear is suitable for AC, 50 Hz, 380 V rated voltage and 3150 A rated current power distribution systems for power plants, transformer substations and industrial & mining enterprises. It is used to transfer, distribute and control electrical energy for power, lightning and power distribution equipment. It has many advantages, such as good breaking capacity & dynamic thermal stability, flexible electrical program, convenient assembly, strong applicability, unique structure and high protection degree.

Working conditions:

• Temperature range: -5 °C to +40 °C, 24 h average temperature ≤ +35 °C.

• Altitude: ≤ 2000 m, indoor application.

• Relative humidity should not exceed 50% at the highest temperature +40 °C, higher relative humidity is allowed at low temperature (90% at +20 °C). Condensation may appear due to temperature change.

• Gradient: ≤ 5°, vertical installation.

• The workplaces should be free of severe vibration, chemical corrosion, fire and explosion.
