OVERHEAD POWER LINE AND OPTICAL FIBER COMPOSITE OVERHEAD EARTH-WIRE

摘要

PROBLEM TO BE SOLVED: To provide an overhead power line having a lighter weight, a less increase in relaxation at a high temperature and a small outer diameter. SOLUTION: Segment aluminum coated carbon fiber composite aluminum element wires 5b are stranded in a sectionally circular shape around a sectionally circular aluminum carbon fiber composite aluminum element wire 5a to form a center tension resistant body 2. Aluminum element wires 3 are stranded on the outer periphery of the center tension resistant body 2 to form the overhead power line.
