AC bushings type HIRIP/RTXF

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)
