FIELD: electrical engineering; automobile and ship building, mechanical engineering, construction , oil extraction, and oil refining industries. ^ SUBSTANCE: proposed electric drive has stranded copper conductor with strand sectional area of 1.0 - 50 mm3 and rubber sheath , 0.4 - 7.0 mm thick, made of rubber mixture whose matrix is polymeric mixture of high-molecular polymethyl vinyl-siloxane and low-molecular polymethyl vinyl-siloxane rubber of mole mass of 20 -70 thousands in combination with silica powder, quartz, anti-texturing agent in the form of alphaomega-dihydroxide methylsiloxane and organic peroxide. Rubber mixture is applied by extrusion at speed of 0.2 - 2 m/s and cured under radiation-chemical curing conditions with aid of cobalt gun incorporating gamma-radiation source at dose rate of 2.5 - 20 megarad. and/or by thermal curing. Electrical conductor produced in the process is capable of fire self-suppression and is suited to operate at -60 to +300 °C. ^ EFFECT: enhanced fire, crack, oil, and gasoline resistance, improved electrical and physical characteristics. ^ 3 cl, 1 tbl
