OPTICAL-FIBER GROUND WIRE Russian patent published in 1998 - IPC

FIELD: electrical engineering; fiber-optic communication lines built in ground wires of high- voltage lines. SUBSTANCE: cable armor is made of lays of wire each incorporating n stranded high-strength and low- conductivity wires and m low-strength and high-conductivity wires; this mechanical design provides for augmented heat transfer between cable sheath and surrounding atmosphere. EFFECT: improved operating reliability of ground wire. 1 dwg
