The present invention relates to a process transmission and distribution line apparatus using an allied cable, and more particularly, to a three-phase cable instead of a conventional separate process transmission and distribution line by manufacturing an allied cable (Aerial Bundled Cable) to install a process line in one pole of Jeonju. It is possible to maximize the transmission capacity by installing many distribution lines of transmission and distribution lines, and by installing the overhead line by tying three-phase cable into a fully insulated allied cable, it is easy to secure the space of electric pole and can safely transport power. The present invention relates to a overhead transmission / distribution line device using a federated cable that can easily cope with environmental changes in the electric power business by reducing weight according to the space occupied by the cable and shortening the pole length.

In general, the large power produced in the power plant is transmitted to each substation with high voltage power through a transmission line using a transmission tower, etc., and then transforms the transmitted power in the substation and is supplied for use in a customer through a process distribution line.

Conventional transmission and distribution lines are installed underground or in the air, when installed in the air is installed by using a support such as a steel tower or pole.

The transmission and distribution lines installed in Jeonju of the support are three-phase four-wire, three-phase three-wire or single-phase two-wire. . Of course, in the case of a transmission line using a transmission tower, more than three lines may be installed.

In the case of using the existing overhead cable, three to four wires per line is composed of one cable line. Therefore, depending on factors such as the installation space and the length of the pole, the number of lines that can be installed in one pole is less than two lines. Was limited to.

In addition, the existing high-voltage processing transmission and distribution lines are separately installed at regular intervals on the arm, so the cable sharing area is very wide, resulting in more contact points for trees, and more tree contacts, resulting in ground faults or magpies. There are a lot of ground faults caused by the tide of birds. As a result, a lot of manpower and expenses are required due to the pruning of tree contact points.

Particularly, in case of special protected forest where tree battery is difficult or when overhead wires are installed on both sides of the road, the underground line is composed of underground lines. There was a problem.

The present invention is to solve the problems as described above, by manufacturing a three-phase cable as a combined cable (Aerial Bundled Cable) instead of the conventional separate processing transmission and distribution line to install a transmission line, a transmission line of many lines in one pole It is possible to maximize the transmission capacity by installing the cable, and it is possible to secure the space of the pole by installing the overhead line by tying the three-phase cable into a fully insulated allied cable. Its purpose is to provide a overhead transmission and distribution line device using an allied cable that can easily change the pole and actively cope with environmental changes in the electricity business by reducing the weight according to the occupied space and the length of the pole.

In order to achieve the above object, the present invention provides a transmission and distribution line of the overhead power cable;
