TENSION CLAMP Russian patent published in 2021 - IPC H02G7/02 

FIELD: electric power industry.

SUBSTANCE: invention relates to the electric power industry, namely to tension clamps for conductors in the form of wires, cables and ropes of overhead power lines, as well as cables of overhead optical communication lines. Tension clamp consists of an outer case with at least one pipe, equipped with the inner case with conical shape, the node, connecting it with other suspension components, bushing located in the inner case, consists of at least one part, and made with conical split collet. Moreover, the cavity of the bushing is made corresponding to the cross-section of the clamped conductor. At the end of the bushing is a spring that rests against the limiter. Inner case has a funnel made of insulating material into the groove of which a centering glass is inserted, holding the end of the conductor and designed for carrying conductor through the bushing. At the same time, elements are applied to the surface of the bushing that ensure guaranteed fixation of the conductor due to a higher degree of coupling of the conductor to other parts of the clamp.

EFFECT: invention provides a tension clamp, which belongs to the class of linear fittings, mounted without expensive technology of pressing the conductors in the clamps, and will allow getting a product that is simpler in design, ease and convenience of installation.
