| description | A polymer bushing includes: an inner conductor; a hard insulating tube; a shielding metal fitting; a polymer covering that includes a body part that covers an outer periphery of the insulating tube, and a plurality of umbrella-shaped sheds that are formed at an outer periphery of the body part; and an electric-field stress-control layer that is composed of a zinc oxide layer or a high-permittivity layer, and is disposed along an interface between the insulating tube and the polymer covering. A rear end part of the electric-field stress-control layer is connected to the shielding metal fitting. The body part includes a first body part that has a uniform thickness, and a second body part that is located in a region around a front end part of the electric-field stress-control layer and has a thickness greater than the thickness of the first body part. |
