SafePlus AirPlus Gas-insulated Compact Switchgear

Medium voltage gas-insulated compact switchgear for secondary distribution, 24 kV, 630A

The SafePlus AirPlus portfolio, covering 24kV applications, is based on AirPlusTM technology as an insulation medium.

The SafePlus with AirPlus insulation gas is the world’s first eco-efficient compact switchgear with a new gas molecule. It is an eco-efficient SF6 alternative for medium voltage and combines the same compact dimensions and advantages of established SafePlus switchgear with a Global Warming Potential (GWP) of less than 1.

 

Benefits

  • AirPlus insulation gas with a Global Warming Potential (GWP) < 1
  • True GIS design: Protected from ambient conditions by sealed gas compartment
  • Easy replacement: Same compact dimensions as the proven SafePlus with SF6 insulation
  • Smart grid enabled
  • Higher personnel safety with internal arc-proof design
  • More flexibility with an increasing range of features
     

Features

  • No SF6 inside: AirPlus insulation gas as an eco-efficient alternative for networks up to 24kV
  • Compact design with a small footprint and low physical weight
  • Independent from ambient conditions
  • Maintenance-free solution
  • Low filling pressure as known from SafeRing with SF6
  • Available with sensor technology and digital communication options
     

Applications

  • Utilities
  • Compact secondary substations (CSS)
  • Light industries
  • Buildings
  • Infrastructure applications

For the eco-efficient switchgear portfolio, ABB has developed a new SF6-free load break switch based on a puffer interrupter technology. This new technology replaces the vacuum interrupter technology used in the C-module of SafeRing and SafePlus eco-efficient switchgear. The new load break switch will function both as a load break switch and disconnector switch, in one single operation. It will further be in series with a two-position earthing switch, which will simplify the operating sequence of the C-module.

The switchgear design is based on the existing SafeRing/SafePlus portfolio, offering an advantage to the end users with the same user interface and footprint. SafePlus AirPlus is a completely sealed system with a stainless steel tank containing all live parts and switching functions. A sealed tank with constant atmospheric conditions ensures a high level of reliability as well as personnel safety and a virtually maintenance-free system.
