FIELD: electrical engineering.
SUBSTANCE: method for prevention of wire rupture consists in that one end of a wire is rigidly fixed, and the second end is laid in a groove on a surface of a spring-loaded cam with a variable rounding radius, having a possibility of rotation. A cam profile and spring parameters are determined by a condition of equality of force moments in the wire and an elastic force of the spring relatively to the axis of rotation of the cam.
EFFECT: increase in a service life of a wire in its icing.
