Hard copper stranded wire, steel core aluminum stranded wire, aluminum alloy stranded wire, etc. are known. Among them, steel core aluminum stranded wire (AC

部材が配置されているため、引張り強さも大きい[0003] Steel core aluminum stranded wire is generally an electric wire in which a galvanized steel wire is twisted in the center and a hard aluminum wire is twisted on the outside. The conductivity of aluminum wire used as a conductor is about 60% that of copper wire, but the weight is about one-third that of copper, so even if the cross-sectional area is increased to flow the same current as copper wire, It can be lighter than using copper wire. In addition, because reinforcing members such as galvanized steel wire are placed in the center, it has high tensile strength.

が増加し、鉄塔への負担が大きくなる。[Problem to be solved by the invention] Such a conventional AC
When a large current flows in the SR, Joule heat is generated,
This caused the wire to expand thermally, increasing its slack and reducing the insulation distance from the ground. Therefore, the current capacity of the conventional ACSR was also determined by such slackness. In order to achieve a larger current capacity, it is sufficient to use a wire with a larger diameter, but using a wire with a larger diameter increases the weight and puts a greater burden on the tower.

の電線を架線することができる。[Operation] In this invention, a wire rod using an aggregate of carbon fibers is used as a reinforcing member. Since carbon fiber has high strength, it is possible to increase overhead wire tension and reduce sag. Furthermore, since it has a low coefficient of thermal expansion, there is little increase in sag when energized. Furthermore, since carbon fiber is lightweight, it can reduce the burden on the steel tower when it is erected, and it is possible to run wires with larger diameters on the same tower.

合体とする必要があるからである。In this invention, carbon fibers are used as aggregates because industrially obtained carbon fibers are several μm thick.
This is because the diameter is approximately 10 μm, and in order to obtain sufficient strength, it is necessary to form an aggregate.

Further, as a coating provided around the carbon fibers, aluminum or an aluminum alloy is generally used, and a coating of aluminum or an aluminum alloy is preferable from the viewpoint of ensuring the corrosion resistance of these coatings.

If the volume ratio is less than 40%, it will not be possible to obtain sufficiently high strength and it will be difficult to obtain a low coefficient of thermal expansion. Moreover, if the volume ratio exceeds 85%, it may become difficult to aggregate the carbon fibers, or the connection strength may decrease.
