Claims20
A corona resistant high voltage bushing assembly, comprising:
- an insulating sleeve to surround a conductor, the insulating sleeve comprised of high strength alumina porcelain;
- a flange located on an outside surface of the insulating sleeve;
- and
- a first band of semiconductive glaze located on the outside surface of the insulating sleeve spaced apart from a first end of the insulating sleeve, the first band including a first plurality of sub-bands of semiconductive glaze having different resistivities.
