PMJ WITH DIFFERENT DIAMETERS AND RUBBER UNIT WITH DIFFERENT DIAMETERS FOR CONNECTION OF ULTRA-HIGH VOLTAGE CABLE WITH DIFFERENT DIAMETERS

WIPO Patent Application WO/2023/177069

A1

The present invention relates to a PMJ with different diameters for intermediate connection between ultra-high voltage cables with different diameters. The PMJ with different diameters for intermediate connection between ultra-high voltage cables with different diameters, according to the present invention, is an intermediate connection PMJ having a pair of connected power cables with different diameters, comprising: a first cable in which a first conductor, a first insulator and a first semiconductor are sequentially formed; a second cable in which the first conductor, a second conductor having a diameter greater than that of each of the first insulator and the first semiconductor, a second insulator, and a second semiconductor are sequentially formed; and a rubber unit of which the inner circumferential surface of one side has a first inner diameter connected over the first insulator and the first semiconductor of the first cable, the inner circumferential surface of the other side has a second inner diameter connected over the second insulator and the second semiconductor of the second cable, the second inner diameter being greater than the first inner diameter and including a central electrode inside the center thereof, and the inner surface of the central electrode has a shape of slanting from one side toward the other side thereof.
