All-insulation phase color preformed armor rod

Abstract

The invention discloses an all-insulation phase color preformed armor rod which comprises a cable, a wire protection strip, a preformed armor rod and a fixing clamp, wherein the wire protection strip wraps the cable, the preformed armor rod winds the wire protection strip, the fixing clamp is arranged outside the preformed armor rod, the fixing clamp comprises an upper clamping plate and a lower clamping plate, one side of the upper clamping plate and one side of the lower clamping plate are rotatably hinged together through a hinge shaft, the other side of the upper clamping plate and the other side of the lower clamping plate are detachably and fixedly connected together, arc-shaped inner-layer clamping plates are arranged on the inner sides of the upper clamping plate and the lower clamping plate respectively, ratchet teeth are arranged on the outer side walls of the inner-layer clamping plates, pawls matched with the ratchet teeth are arranged on the inner side walls of the upper clamping plate and the lower clamping plate respectively, connecting plates are arranged at the two ends of the inner side walls of the upper clamping plate and the lower clamping plate respectively, springs are fixedly arranged on the connecting plates, the other ends of the springs are fixedly connected with the two ends of the inner-layer clamping plate, and grooves capable of containing preformed armor rods are formed in the inner side walls of the inner-layer clamping plate. The all-insulation phase color preformed armor rod has the advantage of preventing the pre-twisted wire from reversing, deforming and loosening.

Description

technical field [0001] The invention belongs to the technical field of electric power maintenance, and in particular relates to a fully insulated phase-color pre-twisted wire. Background technique [0002] Pre-twisted wire is used for connecting fittings for overhead power conductors and power overhead optical cable terminals, suspensions, joints, etc. In its specific application, it is mainly to wrap several wires in a protective line, and then wrap a pre-twisted wire outside the protective line. Twisted wire, that is, the combination of wire and pre-twisted wire, and the end of the pre-twisted wire forms a pull ring end. [0003] The application of pre-twisted wire can protect the wire from damage, prolong the service life, reduce the number of maintenance, improve the service life of the wire, and facilitate the maintenance and repair of the line, and can still maintain the tension and conductivity of the original wire. However, due to The pre-twisted wires are staggered...
