FIELD: aerial power lines. SUBSTANCE: aerial high-voltage power line has phase wires attached to supports by means of insulating hangers. Novelty of method lies in laying of optical cable in central part of split phase. According to this method it is fixed in midpoints of distance pieces installed between wires composing split phase. Besides this optical cable can be laid on hangers attached to wires of split phase. EFFECT: expanded application field. 2 cl, 3 dwg
