FIELD: pyrotechnics; electricity.
SUBSTANCE: invention relates to pyrotechnics and electric power engineering, namely to pyrotechnical clamps intended for fixation of linear fittings and electric power equipment on wires, ropes, lightning protection cables and cables of overhead transmission lines. Pyrotechnical clamp comprises body, pyro-cartridge and striker arranged in case top part. In lower part of housing made in the form of T-shaped profile, on horizontal axis at least two - left and right dies are fixed. End parts of each die are made in the form of a groove with a notch, diameter of the semi-circle of which is selected exactly corresponding to diameter of wires, ropes, lightning protection cables and cables. In transport position, left and right dies are spread apart and retained in fixed position. In the clamp mounting mode, they are compressed by a bracket fixed on the body, providing preliminary fixation of the wire, cable, lightning protection cable or cable in the clamp.
EFFECT: invention makes it possible to achieve strength of sealing at axial displacement along longitudinal axis of wire, rope, lightning protection rope or cable in range from 20 kN to 300 kN.
