FIELD: mechanical engineering. SUBSTANCE: wire cable has at least two layers of strands twisted in opposite directions. Twisting parameters are selected such that whole number of wires is laid on strand surface of one layer between points of contact with two adjacent strands of adjacent layer. Twisting parameters for twisting wires into strands and strands into cable are selected in accordance with design formulas. EFFECT: improved quality of cable by increased strength. 2 cl, 3 dwg
