Claims

[Scope of utility model registration request]

(1) A center conductor is placed coaxially at the center of an insulating tube filled with an insulating medium, and a conical capacitor is placed coaxially around the outer periphery of the center conductor inside this insulator tube, providing high-voltage insulation inside the capacitor. In the bushing having a structure in which a medium is sealed, an electrode is provided at the upper opening edge of the conical capacitor and is electrically connected to the internal electrode thereof, while an electrode is inserted into the opening of the conical capacitor. A bushing characterized in that the center conductor has a large diameter portion formed in a portion facing the capacitor side electrode, and the large diameter portion is provided with a current carrying contact portion that comes into contact with the capacitor side electrode.

(2) The bushing according to claim 1, wherein the current-carrying contact portion of the center conductor has fingers.

(3) The bushing according to claim 1, wherein the current-carrying contact portion of the center conductor has a ramelene band.
