Patent number: 5187009Abstract: There is provided a rubber/plastic insulated power cable or a joint of power cables which comprises a conductor or a conductor joint having an inner semiconductor layer and an insulation layer, and if necessary, an outer semiconductor layer, formed thereon in the order named, at least one of these layers being formed of a crosslinked structure of an olefin resin composition containing an olefin resin, an organic peroxide, and 2,4-diphenyl-4-methyl-1-pentene. The 2,4-diphenyl-4-methyl-1-pentene serves to inhibit "amber" of the olefin resin composition by the organic peroxide used and to increase the degree of crosslinking of crosslinked structure. Also, the olefin resin with a high melting point can be used as a base resin. Therefore, the resultant power cable and joint have highly improved AC breakdown strength, impulse breakdown strength at a high temperature and much less generation of electrical trees due to "amber", so that they are useful particularly high-voltage application.Type: GrantFiled: April 15, 1991Date of Patent: February 16, 1993Assignee: The Furukawa Electric Co., Ltd.Inventors: Hitoshi Kimura, Tetsuo Matsumoto, Michihiro Shimada
