Abstract: FIELD: electrified railways; mounting of compensated and semi-compensated chain catenaries. SUBSTANCE: tension of wires at mounting is preset with due account of wire temperature, their nominal tension at average annual temperature and wire parameters. When determining tension of wires at mounting according to these formulas, heat increment in wire length relative to their length at average annual temperature is compensated by increment in length with opposite sign owing to change in resilient elongation of wires by provision of tensions differing from nominal values. This makes it possible to install brackets, registering cross spans and droppers in vertical planes square to axis of track. EFFECT: increased capacity when mounting contact system at temperatures differing from average annual temperatures. 4 dwg
