FIELD: electricity.
SUBSTANCE: melting the aluminium alloy of the claimed composition and casting the core from the aluminium alloy is carried out. Thereinafter, a three-layer assembly is made of the aluminium core and the concentric bushings of copper and silver, the thickness ratio of the copper layer to the silver layer (HCu:HAg) in the assembly being established equal to 1:(1-1.75) and the same by the wire length. Thereinafter, the operations of pressing into a rod and drawing for wire are carried out.
EFFECT: obtaining a wire with stable mechanical properties and the high level of electrical conductivity in the conditions of prolonged operation at the temperature of about 250 degrees.
