Power line conductors are normally shielded from direct lightning strikes by appropriately placed overhead ground wires. However, even when such overhead ground wires work as intended and intercept a strike, for a short period of time, typically a few microseconds, the shield wire is exposed to an impulse type potential rise. This could be sufficient to cause flashover of one or more line insulator strings. This is called backflash. The present invention solves this problem by providing a power transmission tower structure with an embedded ground conductor positioned in order to optimize the coupling factors to all conductors and reduce stress on all insulator strings through increased electromagnetic coupling. Use of a streamer-inhibited conductor avoids adverse effects such as radio interference and audible noise due to induced charges and improves electromagnetic coupling as a result of the reduced surge impedance of the conductor.

A ground wire with optical fibers is disclosed. The ground wire includes twisted optical modules in the form of plastic tubes that accommodate freely placed optical fibers and water-blocking gel, wherein water-blocking tape applied to twisted optical modules, which are enclosed in a steel tube, coated with an aluminum sheath. The aluminum sheath is helically wrapped with lays of wire. The technical result is provided by increased air tightness of the optical core and permissible crushing stresses.
