LOW WIND NOISE AND LOW WIND PRESSURE DISTRIBUTION CABLE

摘要

PROBLEM TO BE SOLVED: To provide a new distribution cable of low wind noise and low wind pressure, with which an unpleasant wind noise and a wind pressure which causes great damage are greatly reduced. SOLUTION: Multiple grainy bumps 4 are formed throughout the surface of a cable 2. Some grainy bumps 4a are formed larger than the others and laid around the axis of the cable in a spiral fashion, which greatly reduces unpleasant wind noise and wind pressure caused by a strong wind, and prevents noise generation and heavy damage such as a power failure due to fall down of utility poles or breaking of cable.
