２５ａを上記中心導体３の軸線方向に沿って細長く形成
したことを特徴とする高電圧電表機器用ブッシング。The base 2a side of the insulator tube 2 is fixed to the metal case 1, and the center conductor 3 is inserted into the center of the inside, and the space a formed by the center conductor 3 and the inner wall 2c of the insulator tube 2 is made of alumina I. The inner cylinder 4 is inserted, and the inner cylinder 4 and the three center conductors and the metal case 1 and the inner cylinder 4 are sealed with metal pieces 5 and 6, respectively, and thereby the SF6 gas 7 etc. filled in the metal case 1 is sealed. In the case where the insulating medium is kept airtight, the open end 4c of the inner cylinder 4 on the metal case side
The center conductor 3 is passed through the center through-hole 25b, and the outer peripheral end 25c is blocked by an insulating support member 25 in the shape of a cap with a brim attached to a mounting ring 26 integral with the metal case 1. Further, the support member 25 includes the inner cylinder 4.
A bushing for a high-voltage power table device, characterized in that a small hole 25a for gas flow communicating between the inside of the metal case 1 and the inside of the metal case 1 is formed in an elongated manner along the axial direction of the central conductor 3.
