    40.5kV – 550kV Oil-air dry-type condenser transformer/reactor bushing
    • Description
    • Parameter

    Product use:RIP condenser transformer/reactor bushings are mainly used in power transformers/reactors, working as the current carrying conductors for pulling in or drawing high, medium and low voltage side current of transformers/reactors, and playing a role of insulation for oil tank shell of transformers/reactors.

    Service conditions

    · Altitude: 1000m (products can be designed according to altitude correction coefficient if  altitude is higher than 1000m)

    · Ambient air temperature: -45℃- +60℃

    · Installation angle: arbitrarily

    Product structure it is mainly composed of conducting pole, RIP capacitor core, high temperature liquid silicone rubber composite external insulation, equalizing ball, test tap, fittings, etc.

     

    Advantages of bushings

    Ø Unique resin system and special buffer strips

    Ø The most advanced production equipment of the world guarantee the better electrical properties, heat-resistance and mechanical properties of RIP bushings series.

    Ø The lower weight and smaller volume make it easy for transportation, erection and maintenance.

             Ø Oil-free and gas-free design is more environmentally friendly, no risk of explosion;

     

        Ø Excellent performance ensures long-term stable online operation.
