Why EasyDry bushings

  • Easy to use, maintenance-free
    • EasyDry is maintenance- and inspection-free
    • Installation and transportation is possible at any angle
  • Superb design, reliable performance
    • EasyDry bushings utilize only materials which are moisture resistant, making bushing storage and transportation much easier and practical
    •  Easy handling and installation of the bushing thanks to the reduced number of components
    • Single-piece terminal without joints guarantees low resistance current path
    • One-piece, direct-molded silicone insulator provides superior moisture and contamination resistance
  • Oil- and paper-free bushing, highest operational safety
    • EasyDry bushings are explosion-proof since they are oil- and pressure-free
    • The EasyDry bushing’s core material makes it fire-resistant
    • Hydrophobic, non-shattering silicone insulator with outstanding contamination performance
  • Excellent electrical and thermal properties
    • Partial discharge-free up to double service voltage
    • High thermal endurance (class E, 120 °C)
    • Low dielectric losses (tan δ < 0.35 %)
  • Environmental friendly
    • The materials are selected to provide the lowest possible environmental impact over the whole product life cycle
    • Lower carbon footprint than other bushing technologies
