Oil-air bushing is mainly used for power transformer as current carrier for leading in andout current of high voltage side, middle voltage side and low voltage side of transformeras well as insulate the oil tanks of power transform.

Oil-oil bushing is mainly used in power transformer and rectifier transformer, connecting cable through transition conservator as well as insulate oil tanks and transition conservator of power transform .

 

Oil- SF6 bushing is mainly used as transition connector for oil power transformer to GIS or SF6 bus. One end of bushing is in oil, the other end is in SF6 during operation. The Max. temperature for SF6 medium should be 40 ºC , should be not more than 0.55Mpa(gauge pressure)

Wall bushing is mainly used in power station and substation for high voltageconductor pass through wall or floor.Dry wall bushing is solid insulation, with advantages of good antipollutionperformance, high reliability,no oil leakage, no environment pollution, small size.light weight, easy mounting and maintenance-free.

RIP DC bushing uses resin impregnated paper process, and applied to all voltage levels bushing. The condenser core of this bushing is cured after impregnated with resin epoxy under high vacuum .With advantages of high mechanical strength, strong seismic resistance capability, good thermal stability, reliable insulation, low partial discharge, easy mounting and maintenance.

RIP DC bushings are applied in many DC projects and have broad market prospects.

 

Comprehensive technical capability of RIP DC bushings produced by our company reach the international advanced level, with independent intellectual property rights. Our RIP DC bushings can replace imported products.
