FIELD: electrical engineering.
SUBSTANCE: clamp for fixation of short-circuit indicator (SCI) on wire of overhead transmission line installed in upper part of SCI housing, contains two brackets: clamping and thrust, intended for covering and holding between them wire of overhead transmission line. Brackets are installed on axes fixed on the clamp base, and have the possibility of rotation on these axes, at that, the clamping bracket is equipped with a spring intended for movement of this bracket to the support bracket, support bracket is provided with a spacer rod-lug capable of retaining the thrust clamp from the clamping bracket at a distance which enables the wire to enter the clamping space of the staples, and thrust clamp is equipped with folding thrust lever holding it in fixed position relative to clamp base in position "SCI on wire". At that, in "SCI on the wire" position between the clamping bracket and the stop on the clamp base there is a gap allowing the staple bracket to turn off when the folding stop lever is turned upwards due to the force developed by the clamping bracket.
EFFECT: simple process of installing a short-circuit indicator (SCI) on a high-voltage transmission line, high reliability of its attachment due to creation of a large compression force of the clamp on the wire with insignificant force during attachment and removal, as well as simplification of manipulations when securing and removing using an insulating rod.
