摘要

A cylindrical pre-molded rubber insulation tube made by a plurality of layers using a rubber material as a base material has in a central part and at both ends of an inner periphery thereof a sheet-shaped electrode layer formed at an insde thereof with a semi-conductive rubber layer and at an outside thereof with a high-permittivity rubber layer, as an inner electrode layer configured with the semi-condutctive rubber layer to be thin and sheet-shaped and the high-permittivity rubber layer covering a vicinity of a respective distal end of the semi-conductive rubber layer, and the distal end of the semi-conductive rubber layer is rounded by a radius of curvature substantially equal to half the thickness.
