FIELD: physics.
SUBSTANCE: steel cord comprises a core formed by two parallel to each other core filaments 1 without twisting, and N (2≤N≤4) sheath filaments 2 which are twisted together around core. With diameter d1 of core filament 1 and diameter d2 of sheath filament 2 d1>d2, wherein ratio d1/d2 ranges from 1.1 to less than 1.7.
EFFECT: technical result is improvement of characteristics of reinforced rubber articles, reducing tyre weight without reducing its service life.
