Cable termination connections with fittings integrated stress cone and this

摘要

PROBLEM TO BE SOLVED: To improve sealability of an oil-proof structure by reducing the number of parts.;SOLUTION: A stress cone integrated with metal fitting has: a stress cone 2 composed of a cylindrical rubber-like elastic body to be fitted over an outer circumference of a cable core; and a metal fitting 3 which surrounds the cable core and is prepared on a low voltage side of the stress cone in a body therewith. The stress cone includes: a cylindrical semiconductive body portion 5 which is arranged on the low voltage side and has an electric field relaxation part 51 like a bell mouth at its end on a high voltage side; an insulating portion 6 which is arranged on the high voltage side coaxially with the semiconductive body portion, and has an end on the low voltage side joined to the electric field relaxation part; and a cylindrical insulating protective layer 7 which is formed over an outer circumference of the semiconductive body portion in a body therewith, being joined to the end on the low voltage side of the insulating portion.;COPYRIGHT: (C)2009,JPO&INPIT
