Features

Reliability
  • Type testing is completed according to IEC62271-200
  • Internal arc proofed 21kA/1sec A-FLR
  • Earthing of both the entire switchboard structure and the metal division between compartments
  • Mechanical interlocks assure exact operation sequence
  • Protection classes: PI (insulating partition)
  • Loss of service continuity classes: LSC2A (LSC1 for bus riser)
  • IP3X protection degree on the external housing
Optimization
  • Reduced dimension and weight
  • Less space requirement for switchboard installation
  • Easy integration in factory-built outdoor substations
  • Adapted solutions to cable connection
  • Modular units containing fixed and withdrawable metal-enclosed switchgear, using vacuum
Simplicity
  • Simplified switchboard busbar design
  • Mimic diagram in front of the switchboard using simple and functional devices
