Abstract: 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.

Abstract: This handle heater comprises a mesh heating body comprising a plurality of heater wire strands woven into mesh, and electrodes disposed at both ends of the mesh heating body. Each of the electrodes comprises a metal foil whereon the mesh heating body is welded, and an insulating protective tape sandwiching, by being folded back along the width direction of the mesh heating body, the front and back surfaces of an electrode base body containing the metal foil and one of the ends of the mesh heating body. The mesh heating body is disposed in such a manner that each end in the length direction thereof follows an edge surface of the corresponding metal foil, and a space is present between the length direction end of the electrode base body and the folded-back portion of the protective tape.
