GCS Low Voltage Withdrawable Switchgears for Power Distribution Systems

A GCS low voltage withdrawable switchgear.
GCS low voltage withdrawable switchgear.

GCS low voltage withdrawable switchgear is designed according to the requirements of industry department, the majority of electricity users and design companies. It has high technical performance indicators and it can adapt to the development needs of electricity market. This kind of switchgears are widely used for power distribution systems of many industries, such as power plants, petroleum, chemical engineering, metallurgy, textile and high-rise buildings. It is used as complete low voltage power distribution device for power generation & supplying systems of three-phase, AC, 50 Hz/60 Hz, 380 V/400 V/660 V rated voltage, 4000 A rated current. It is also used in the places where automation is high and connected with computer interface is required, such as large power plants and petrochemical systems.

Working conditions:

  • Temperature range: -5 °C to +40 °C, the average temperature within 24 hours should not exceed +35 °C.
  • Altitude: ≤ 2000 m, indoor application.
  • The relative humidity should not exceed 50% at the highest temperature +40 °C, and higher relative humidity is allowed at low temperature (90% at +20 °C). Condensation may appear because of temperature range, and this phenomenon should be considered.
  • Gradient: ≤ 5°, vertical installation.
  • Workplaces should be free of fire, explosion, severe vibration and chemical corrosion.
