OVERHEAD POWER CABLE

摘要

PROBLEM TO BE SOLVED: To provide an overhead power cable that is lightweight and has a large tensile strength and a little thermal expansion. SOLUTION: An overhead power cable is configured to have a higher concentration of ceramic on a surface of carbon fiber with ceramic produced and coated gradiently from a carbon fiber surface to the inside of the carbon fiber. Use of a composite wire rod with aluminum or aluminum alloy combined with the gradually produced and applied carbon fiber makes it possible to make the wire rod more lightweight and stronger than conventional materials. The overhead power cable consists of a composite wire rod that does not deteriorate under fatigue conditions such as heat cycles.
