Claims

[Scope of utility model registration request]

(1) A cylindrical support fitting that surrounds the center conductor with an insulating layer around it, an insulator tube that is oil-tightly connected to both ends of this support fitting, and an expansion chamber that connects these support fittings and insulator tubes from both ends. 1. A bushing which is integrally tightened by a flange via a scissor spring and the conductor, and wherein the joints between the paddle tube and the support fitting and the paddle tube and the flange are covered with a heat-shrinkable insulator.

(2) The bushing according to claim 1, wherein the heat-shrinkable insulator is fixed with an insulating tape.
