<p>PROBLEM TO BE SOLVED: To solve problems that a conventional rubber insulation pipe formed by an inner semiconductor layer, an insulating layer and an outer semiconductor layer, and used for jointing of CV cables needs a metal mold for each layer in production by its structure, resulting in a long production hour, and a high cost. SOLUTION: It has features that the cylindric rubber block is made using a rubber material as a base, an inner electrode layer is formed as a thin sheet like layer and a high dielectric constant insulating layer is formed while protruding from interfaces of both ends.</p> |
