Description

cable terminal tower

technical field

The utility model relates to the technical field of electric power transportation, in particular to a cable terminal tower.

Background technique

Cable terminal towers are used at the junction of high-voltage overhead lines and high-voltage cables. The cable terminal tower in the prior art requires two tall steel pipes to form a support, which not only wastes steel but also takes up a large land area; in addition, the existing cable terminal tower does not have the location for installing lightning arresters, so that the existing cable terminal tower There are many inconveniences in the installation process of lightning arresters.

Contents of the invention

Aiming at the above problems, the utility model provides a cable terminal tower, which can effectively save steel consumption and occupied land area by using the terminal tower to connect high-voltage overhead lines and high-voltage cables.

According to the technical solution of the utility model: a cable terminal tower, the feature is that: it includes a tower rod and an independent bracket arranged on one side of the tower rod, and a plurality of wire cross arms are arranged on the tower rod. A first support frame and a second support frame are sequentially arranged under the cross-arm of the conductor on the pole, and three cross-arm type support insulators are respectively arranged on the second support frame and the first support frame, and the first support frame and the cross-arm A lightning arrester is arranged at the connection of the supporting insulator; the top of the independent support has a terminal platform, and a cable terminal head for fixing cables is arranged on the terminal platform.

As a further improvement of the utility model, five wire cross arms are arranged from top to bottom on the tower pole, and tension insulator strings are arranged on three wire cross arms in the center.

As a further improvement of the utility model, jumper synthetic insulator strings are arranged at the ends of the second and third wire cross arms from top to bottom of the tower pole.

The technical effect of the utility model lies in that the utility model reduces the support composed of two tall steel pipes to one steel pipe by improving the technology of the existing cable terminal tower, which effectively saves the use of steel materials At the same time, the utility model also presets the installation station specially for the installation of the arrester; in the specific use process, the utility model reduces the occupied area because there is only one steel pipe.
