Description of the Related Art A multi-conductor power transmission line of this kind is mounted with a slack in the lower part of the middle of a plurality of main conductors and between two main conductors on the ground side of the plurality of main conductors. The line conductor is supported by the two main line conductors on the ground side by the supporting portions at intervals in the longitudinal direction.

The support part consists of a spacer with a clamp, and the line conductor is supported by the two main conductors on the ground side by this spacer. If this spacer is made conductive so that a current flows through the line conductor, Since the current flowing through the conductive spacer causes the movable portion of the spacer to generate heat, conventionally, an insulating spacer is used to support the line conductor on the ground-side main line conductor.

った。However, if the line conductor is supported by using an insulating spacer that does not allow a current to flow in the line conductor, the line conductor is relaxed in order to reduce the surface potential gradient of the main line conductor on the ground side. A semiconductive organic material is interposed between the main line clamp of the spacer or between the main line clamp and the main line conductor so that the same potential is maintained between the main line conductor and the main line conductor and the current is not shunted to the main line conductor. Therefore, there is a fear that the organic substance deteriorates due to long-term use and the original function of the organic substance is deteriorated.

送電線路。1. A plurality of main wire conductors, and an attached wire conductor that is laid with a slack in the lower part of the middle of the two main wire conductors on the ground side among the plurality of main wire conductors. In the multi-conductor transmission line in which the line conductors are supported by the two main line conductors on the ground side at intervals in the longitudinal direction by supporting portions, the line conductors are provided at any one position for each independent conductor. In the multiconductor transmission line, the electric conductor is electrically connected to the two conductors on the ground side.
