The main insulation of the AC bushing type RMI for wall application is a core of solid insulation resin-impregnated paper (RIP) with condenser layers for field control. This material complies entirely with modern requirements for a high-quality insulation system, particularly regarding partial discharge behavior.​


  • Flexible design allows for adaptation to different customer needs​
  • Completely dry bushing, i.e., no oil spills, no explosion risk​
  • No maintenance or constant monitoring is necessary
  • Transport and storage are possible in all positions​
  • Partial discharge free up to double service voltage​
  • High-temperature resistance (class E, 120°C)​
  • Low dielectric losses (tan< 0.40%)​

Product scope:

  • Voltage: 24 - 300 kV
  • Current: ≤ 5000 A
  • Technology: Resin impregnated paper (RIP)
