Abstract

PURPOSE:To obtain a high dielectric breakdown voltage by a method wherein a plastic tape having fine roughness at one side or both sides is wound on the outside of a conductor and an insulating layer is formed. CONSTITUTION:An insulating layer 2 is provided at the outside of a conductor 1. The layer 2 is formed by winding one or more than one plastic tape on the outside of the conductor 1. Fine roughness is provided at at least one side or both sides of the plastic tape. When the roughness exceeds 0.03mm. in depth, dielectric voltage suddenly drops. Even if the roughness is 0.0003mm. or less in depth, the dielectric voltage also drops. Therefore, preferable roughness at the surface of the plastic tape is within a range of 0.0003-0.03mm..
