An overhead conductor unit used for transmitting high voltage, alternating current, electrical energy which comprises one conductor or several metallic wires grouped together and a thin plastic cladding, a resin or resin-rubber, around the conductor or wires. The plastic cladding includes at least one conductive composition, generally, carbon black, in an amount of 5-40 parts by weight and at least one hydrorepellent composition present in 1-10 parts by weight. The thus obtained overhead conductor unit reduces, or prevents, corona noises when the unit becomes wet. |
