摘要：

A bushing wherein the voltage stress across the surface of the bushing is alleviated by placement of a layer of insulating material in direct contact with the surface. The insulating material is preferably a high-voltage type, heat-shrinkable, halogen-free polyolefin, and is preferably fully shrunk to conform to the contours of the outer surface of the bushing.
