FIELD: electrical engineering; fiber-optic communication lines built into ground wires of high-voltage lines. SUBSTANCE: ground wire has central power member, optical fibers in insulating tubes, and metal sheath with round-wire armor overall. Heat- resistant insulating member is wound on insulating tubes at winding pitch greater than external diameter of metal sheath; thickness of heat-resistant insulating member is greater than that of metal sheath. EFFECT: improved operating reliability due to better heat transfer between metal sheath and surrounding atmosphere. 1 dwg
