FIELD: electrical engineering.
SUBSTANCE: proposed device that can be used in erection of high-voltage overhead power transmission lines to attach conductor to pin insulator and to protect it against damage caused by fatigue vibrations has spiral clamp incorporating preformed flexible spiral wires secured on one end within steel sleeve by way of compression; sleeve is threaded for connection to insulator cap.
EFFECT: facilitated manufacture and installation on insulator and conductor dispensing with special tools.
