AERIAL POWER TRANSMISSION LINE Russian patent published in 1997 - IPC

FIELD: electric engineering. SUBSTANCE: temperature compensators which are made from material which has memory shape effect are introduced to accomplish goal of invention. Said temperature compensators are connected in parallel to wire, are controlled by load current. To achieve this wire under temperature compensators is covered by ferromagnetic screen. Finishing temperature of reverse martensite transition of material which has memory shape effect is equal to wire temperature which is required for firing temperature compensators; ferromagnetic screen which is required for firing temperature compensators is chosen for aerial transmission line current which heats wire up to temperature when temperature compensators are fired under conditions of minimal environment temperature and calm wind. EFFECT: compensation of conductor sag caused by temperature. 1 dwg
