Detalii

Environmentally friendly solution

The gas-insulated switchgear ENK is an innovative solution for meeting future requirements of the evolving smart power grid. It is the ideal solution for reliable supply and generation up to a rated voltage of 72.5 kV, a rated continuous current up to 2500 A, and a rated short circuit current up to 40 kA. The state-of-the-art design of ENK is composed of a minimum number of highly integrated functional modules that are easily and quickly installed on site. The compact, three-phase enclosed design fits even the smallest installation site.

Why ABB?

  • ABB offers solutions optimized for ratings up to 72.5 kV, 2500 A and 40 kA
  • Minimum installation time
    • Shipment of complete, factory tested bays in standard containers
    • Reduced gas handling due to plug-in busbar connections (similar to medium voltage switchgear)
  • Eco-efficient with 50 percent less SF6 gas than predecessor products, reduced thermal losses and compact lightweight design
  • Monitoring, control, protection and communication features for smooth integration into digital substation systems using IEC 61850
