INSULATOR TYPE SUPPORING BAR OF ELECTRIC FOR FASTENING OVER HEAD DISTRIBUTION LINE

摘要

The purpose of an insulator type utility pole for an overhead distribution line is to pull both ends of the overhead distribution line with a tension change when the tension change therefor is detected; to prevent sagging of the overhead distribution line by pushing force control from a weight by the pressure roller; to minimize shaking by limiting a shaking of the overhead distribution line; to prevent damage to a suspension insulator by controlling the tension change shrinking or drooping of the overhead distribution line.
