FIELD: electrical engineering.
SUBSTANCE: invention relates to spiral binding attachment intended for fastening insulated and non-insulated wires of 0.22-35 kV overhead power lines to pin and support insulators, made at least in the form of one wire with a central part and two end sections of a spiral shape with a length of at least three spiral winding paths each, with an abrasive material glued to at least the inner part of the end sections or a coating with a high friction ratio is applied in a continuous layer or in separate sections, characterized in that the wires are made of non-magnetic material.
EFFECT: spiral binding design is characterized by low losses for reversal of magnetization, high reliability during the entire service life, low cost and versatility of application on various overhead power transmission lines.
