Abstract
The invention relates to the technical field of electric power transmission, in particular to a cable terminal tower. The cable terminal tower comprises a pole and an independent support which is arranged on one side of the pole, wherein a plurality of wire cross arms are arranged on the pole; a first support and a second support are arranged under the wire cross arms on the pole in sequence; three cross-arm supporting insulators are respectively on each of the second support and the first support; lightning arresters are arranged on the connecting parts of the first support and the cross-arm supporting insulators; a terminal platform is arranged on the top of the independent support; and a cable terminal used for fixing a cable is arranged on the terminal platform. When the cable terminal tower is used for connecting with a high-voltage overhead line and a high-voltage cable, the steel consumption and the occupied land area can be effectively saved.
Description
Technical field
The present invention relates to electric power transportation technology field, specifically a kind of cable termination tower.
Background technology
The 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 bigger land area; Existing cable termination tower does not possess the position that lightning arrester is installed in addition, makes the lightning arrester of existing cable terminal tower have the inconvenience part in installation process.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of cable termination tower is provided, adopt this terminal tower to connect high voltage overhead lines and high-tension cable, the land area that can effectively save the steel consumption amount and take.
According to technical scheme of the present invention: 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, described tower bar is provided with several lead cross-arms, below described tower bar upper conductor cross-arm, be disposed with first bracing frame, second bracing frame, 3 cross-arm formula supporting insulators are set on described second bracing frame and first bracing frame separately, and are provided with lightning arrester in the junction of first bracing frame and cross-arm formula supporting insulator; Described independent rack top has terminal platform, and described terminal platform is provided with the cable terminal for attached cable.
As a further improvement on the present invention, 5 lead cross-arms are set from top to bottom on the tower bar, 3 lead cross-arms placed in the middle therein are provided with strain insulator string.
As a further improvement on the present invention, be provided with wire jumper composite insulation substring in the end of tower bar second, third lead cross-arm from top to bottom.
Technique effect of the present invention is: the present invention with the support that the existing cable terminal tower is made up of two tall and big steel pipes, is reduced to a steel pipe, the use amount of effectively having saved steel by the existing cable terminal tower is carried out technological improvement; The present invention simultaneously also presets the installation station for the installation of lightning arrester specially; In concrete use, the present invention has reduced floor space owing to have only a steel pipe.
