Abstract

The invention relates to a transmission line insulation device, which includes a shell, an insulating inner core and an outer seal. The shell includes a base part and an extension part. The base part is a cylinder with side openings. The center of the cylinder is the inner cavity of the base part. It is used to accommodate oppositely connected transmission lines. The extension part includes two upper and lower triangular extension pieces. The concave cavity in the extension piece and the inner cavity of the base part together form the insulating inner core accommodation cavity; the insulating inner core is placed in the insulating inner core accommodation cavity. Inner and outer seals are used to seal the gaps in the enclosure. The device is suitable for vertically intersecting transmission lines, and has the advantages of quick installation and good insulation performance.

Description

Technical field [0001] The invention involves an insulation device of a transmission line, which specializes in an insulation device that is particularly intersecting the vertical intersection of the transmission line. Background technique [0002] In the existing technologies, the insulation tape is used for insulation treatment when the transmission line is vertically intersecting. This processing is more troublesome, and the insulation performance cannot be guaranteed, and the possibility of leakage occurs.Therefore, there is a need to have a good insulation performance and fast installation insulation device. Invention content [0003] The purpose of the present invention is to provide a transmission wire insulation device. This device is suitable for vertical intersection transmission lines, which has the advantages of fast installation and good insulation performance. [0004] In order to solve the above technical problems, the technical solution of the present invention i...
