Abstract

A pylon 1 supports at a level above the ground at least one overhead electric power line 4. A coaxial shielded conductor 20 includes a central conductor core, an outer conducting sheath, and an insulating layer between the core and the sheath. The upper end of the core is electrically connected to a conducting member 2 adjacent the top of the pylon 1. Both the lower end of the core and the lower end of the sheath are grounded. The sheath extends from substantially the area of connection of the core to the conducting member 2 to a position below the power line 4, such that the lower end of the sheath is spaced below the power line 4 at least by a distance sufficient to exclude the formation of a discharge arc between the core and the power line upon a lightning discharge.
