SWICHGEAR Parts Environment-Friendly Gas Insulated Switchgear

Environment-Friendly Gas Insulated Switchgear

The 25.8 kV EGIS is installed at KEPCO substations as an eco-friendly switchgear applying dry air, and is a product with safety secured via arc-suppression certification, used as a switchgear at digital substations with mounted IED based on IEC 61850.

Product characteristics 

  • Interrupter and operational machinery apply a permanent magnetic actuator (PMA) mechanism with over 10,000 operational
    cycles guaranteed [Maintenance Free]
  • Enables access to internal components and easy management, unlike the sulfur hexafluoride(SF6) gas-insulated switchgear
  • Improves operational reliability through mechanical and electrical secondary interlocking functions between the circuit breaker,
    disconnecter, and earthing switch (CB, DS, ES)
  • Useful for additional construction following future increases in substation capacity
  •  Insulation reliability
