DOUBLE-CIRCUIT AERIAL ELECTRIC POWER LINE WITH TAPPINGS Russian patent published in 1994 - IPC

FIELD: electrical engineering. SUBSTANCE: aerial electric power line is suspended from supports 1 with horizontal arrangement of wires 2 which are attached to supports 1 with the aid of insulator strings 3. Tapping supports 4 are manufactured for single - or double-circuit versions. Tapping wires 7 are attached to wires 2 of circuit which is external with reference to tapping circuit by means of additional insulator strings 5 and V-shaped strings 6. Wires 8 of tapping from internal circuit with respect to tapping are attached directly. EFFECT: enhanced reliability of power line and tappings. 4 dwg
