FIELD: technology for supplying energy to shift settlements of woodsmen, oil industry workers, geologists, gas industry workers, bridge builders and other specialists. ^ SUBSTANCE: temporary electric air line includes aerostat supports, isolating packets with rigid inserts, while phase cables are positioned in one vertical plane and are connected to rigid inserts of isolating ropes, while in runs of line phase cables are interconnected by rigid isolating spreaders. Above phase cables, bearing storm-protective cable is positioned, and in line run, rigid isolating spreaders are connected to bearing storm-protective cable. Storm-protective cable can be held on upper end of isolating cable. Cable in line run is positioned with sag arrow. Lower phase cable is positioned above trees of forest tract. ^ EFFECT: decreased costs of preparatory works due to no need for making forest cuttings, shorter mounting time due to fast transporting of line, increased safety of line operation due to prevention of possible falling of trees on phase cables. ^ 3 cl, 1 dwg |
