HIGH-VOLTAGE WIRE FOR AERIAL POWER LINES OF ABOUT 60 kV Russian patent published in 1999 - IPC

FIELD: electrical engineering, high-voltage wires designed for aerial power lines with voltages of about 60 kV and higher. SUBSTANCE: in correspondence with invention wire is coated with insulation and is screened against spark break-down emerging as result of contact with another wire. Insulation coat on wire has semi-conducting layer embracing wire, outer atmosphere-protected surface layer of insulation and layer actually ensuring insulation located between them. EFFECT: construction of aerial power lines which require narrower land strips under them and reduced electrical and magnetic fields. 3 cl, 1 dwg, 1 tbl
