Excellent thermal stability, with low dielectric losses even athigh operating temperatue (such as 90°C).*Equipped with test tap for tan δ and partial discharge measurement on transformer. * Less maintenance and resistance to aging.
* Hermetically sealed with separate oil system. * The lower end of bushing is protected by porcelain shell which makes the bushing sturdy and prevents the permeation from impurities and moisture.
* Better mechanical property and resistance to earthquake
