FIELD: electricity.
SUBSTANCE: invention relates to protected wires for overhead transmission lines. Wire contains one current-conducting core 1, twisted from wires from aluminium alloy, on top of which there is electroconductive layer 2 and two-layer protective insulation. Inner layer 3 is made of a cross-linked composition based on polyethylene, which does not contain soot. Outer layer 4 is made of polymer base containing soot, substituted hydroxybenzophenone, magnesium hydroxide or aluminium hydroxide in amount of not more than 15% by weight.
EFFECT: high resistance to aging.
