Abstract

The invention discloses a sealing assembly of an oil-filled cable terminal, comprising: a metal tube; a first elastic sealing member molded on the outer peripheral surface of the metal tube, and used to realize the axial direction of the oil-filled cable terminal; sealing; and a second elastic seal molded on the end of said metal tube for achieving radial sealing of said oil-filled cable termination. In the present invention, the first elastic sealing member and the second elastic sealing member of the sealing assembly can realize axial sealing and radial sealing of the oil-filled cable terminal respectively, thereby improving the sealing performance of the oil-filled cable terminal. In addition, the metal tube of the sealing assembly has good electrical conductivity, which improves the grounding performance of the cable.

Description

technical field [0001] The invention relates to a sealing component of an oil-filled cable terminal and an oil-filled cable terminal comprising the sealing component. Background technique [0002] High-voltage oil-filled power cable terminal products are currently the main product form of high-voltage power cable terminals. Especially in the UHV cable terminal product system, almost all outdoor cable terminals are oil-filled cable terminal products. However, since the oil-filled cable terminal needs to be filled with insulating oil, an axial seal and a radial seal are required at the bottom of the oil-filled cable terminal product. Due to the creeping of the cable during operation, it is very difficult to radially seal the surface of the cable, and oil-filled terminal products are prone to oil leakage. In addition, reliable electrical connection must also be considered in the design of the sealing part. Since the sealing material of the sealing part is generally a non-met...
