FIELD: process engineering.
SUBSTANCE: invention relates to production of cables and can be used for production of naked conductors of higher flexibility and conductivity for application as conductors of choke, interchoke, intertrack jumpers and electric traction connectors of rail circuits and as connectors in electric power engineering. In production of steel-copper conductors with conductivity of 50-60% of copper conductors of the same cross-section are subjected before twisting to annealing in noncorrosive atmosphere at 630-700°C while twisting is executed under conditions that rule out twisting of steel-copper wired about their axes.
EFFECT: higher resilience at cyclic flexure and twisting in operation.
