HIRIP outdoor transformer bushings are designed for the most demanding high-current applications. The dry bushing technology provides users with safety and quality performance uniquely combined with thermal and electrical engineering developments for applications of up to 40,000 amperes.​

Hitachi Energy has access to comprehensive resources, especially in high-voltage engineering, materials research, and applied physics. The continuously improved design of our RIP high-voltage bushings sets new standards regarding quality, reliability, and safety.

  • Highest operational safety with fire-resistant and explosion-proof designs​
  • Maintenance and inspection-free bushing​
  • Reduced number of components for simplistic design
  • Operation at low temperatures, down to –25°C
  • No joints (welding/brazing) in the current path reduces electrical resistance
  • The integrated terminal pads of the conductor guarantee a better current distribution in the conductor
  • Integrated cooling ribs, mechanically protected
  • Very long creepage distance for maximum protection


 

Product scope:

  • Voltage: 36 kV
  • Current: 5000 - 40000 A
  • Technology: Resin impregnated paper (RIP)
