題点があった。[Problems to be Solved by the Invention] However, such conventional gap-type ACSRs have a problem in that they are heavy because a steel core is used as a reinforcing material. In addition, in order to increase the power transmission capacity, it is necessary to increase the area of the aluminum that is the conductor, and the diameter of the steel core that is the reinforcing material also increases, creating the problem that it becomes even heavier. Furthermore, when the temperature of the central steel core, which is a reinforcing material, increases due to energization, there is a problem in that the degree of sag increases.
