Abstract

The utility model relates to the electric power transportation technology field and especially relates to a cable termination tower. The tower comprises a tower rod and an independent support arranged on one side of the tower rod. The tower rod is provided with several lead cross arms. A first support frame and a second support frame are successively arranged below the lead cross arms on the tower rod. The second support frame and the first support frame are provided with three cross-arm-type support insulators respectively. A lightning arrester is arranged on a connection position of the first support frame and the cross-arm-type support insulators. A top of the independent support possesses a terminal platform. A cable termination head used to fix the cable is arranged on the terminal platform. The termination tower is used to connect a high voltage overhead line and a high voltage cable so that steel material consumption and an occupied land area can be effectively saved.

Description

Cable termination tower
Technical field
The utility model relates to electric power transportation technology field, specifically a kind of cable termination tower.
Background technology
Cable termination tower is used for the junction of high voltage overhead lines and high-tension cable.Cable termination tower of the prior art needs two tall and big steel pipes to form support, not only wastes steel but also need to take larger land area; Existing cable termination tower does not possess the position that lightning arrester is installed, so that there is the inconvenience part in the lightning arrester of existing cable terminal tower in installation process in addition.
Summary of the invention
The utility model provides a kind of cable termination tower for the problems referred to above, adopts this terminal tower to connect high voltage overhead lines and high-tension cable, effectively saving steel consumption and the land area that takies.
According to the technical solution of the utility model: a kind of cable termination tower, it is characterized in that: comprise the tower bar and be arranged at the independent rack of tower bar one side, be provided with several wire cross-arms at described tower bar, below described tower bar upper conductor cross-arm, be disposed with the first bracing frame, the second bracing frame, 3 cross arm type supporting insulators are set on described the second bracing frame and the first bracing frame separately, and are provided with lightning arrester in the junction of the first bracing frame and cross arm type supporting insulator; Described independent rack top has terminal platform, is provided with the cable terminal for attached cable on the described terminal platform.
As further improvement of the utility model, 5 wire cross-arms are set on the tower bar from top to bottom, be provided with strain insulator string on 3 wire cross-arms placed in the middle therein.
As further improvement of the utility model, be provided with wire jumper composite insulation substring in the end of tower bar second, third wire cross-arm from top to bottom.
Technique effect of the present utility model is: the utility model by the support that two tall and big steel pipes form, is reduced to a steel pipe, the use amount of effectively having saved steel with the existing cable terminal tower by the existing cable terminal tower is carried out technological improvement; The utility model also presets the installation station for the installation of lightning arrester specially simultaneously; In concrete use procedure, the utility model has reduced floor space owing to only have a steel pipe.
