摘要： PROBLEM TO BE SOLVED: To relieve an electric field in an insulating gas by a composite insulation structure, improve the withstanding voltage characteristics and reduce the dimensions as a whole by a method wherein a protrusion is formed in the circumferential direction of conductor end electrode or along the outer circumference of the conductor end electrode, and the protrusion is cover with an approximately semispherical insulating layer whose tip part has a required curvature. SOLUTION: A semicircular protrusion 12a is formed on the end part of an electrode 12, along the outer circumference. Further, an insulating layer 13, made by molding of epoxy resin is formed, so as to overlap the straight part in the axial direction of the electrode 12 by several millimeters. the tip part of the insulating layer 13 has a proper curvature and faces a grounding metal plate 14. Even if the grounding metal plate 14 is replaced by the conductor of the other phase, etc., the condition is the same. That is, the insulating layer 13 is formed, so as to face a part where a potential difference produced. If the thickness (t) of the insulating layer 13 is about 1/2 of the distance (1) between the electrode, the electric field intensity can be minimized, and the voltage withstanding characteristics can be improved most.
