Problems solved by technology

[0003] The current spacer clamps have many parts, the process is relatively complicated, and the cost is relatively high. In addition, because the chucks of the clamps are all clamped, the clamp body and the pressure plate clamp the wires through a hinge. When installing, a special installation tool must be used to press the clamp body and the pressure plate tightly, and then lock the pressure plate firmly with pins

Abstract

The invention relates to the technical field of spacers, and discloses a pre-twisted spacer, which comprises a supporting frame, wire clamps and pre-twisted wires. The supporting frame is composed of two supporting plates and a connecting piece, the connecting piece is located between the two supporting plates, and the supporting plates and the connecting piece are connected through bolts; the two wire clamps are arranged at the two ends of the supporting frame respectively. The wire clamp comprises a wire frame, a positioning frame, a semicircular ring, a fixing block and a screw rod. When the pre-twisted spacer is installed, the wire clamp is opened and clamped on a cable, the screw rod is rotated to close the wire clamp, so that the wire clamp is hung on the cable and cannot clamp the cable, stress concentration cannot be formed, the performance of the cable cannot be influenced, the pre-twisted wire is matched to be wound on the cable, and the wire clamp is fastened on the cable, so that the installation of the spacer is completed.

Description

technical field [0001] The invention relates to the technical field of spacer bars, in particular to a pre-twisted spacer bar. Background technique [0002] The spacer rod refers to the fittings installed on the split wires to fix the distance between the split wires, so as to prevent the wires from whipping each other, suppress the breeze vibration and the sub-gap vibration. The spacer is generally installed in the middle of the span, installed at an interval of 50-60m, the spacer of the two-split, four-split, six-split, and eight-split conductors, and the vibration amplitude of the split conductor after installing the spacer is compared with that without the spacer. 50% smaller, 87% smaller for four-split wires, 90% smaller. [0003] The current spacer clamps have many parts, the process is relatively complicated, and the cost is relatively high. In addition, because the chucks of the clamps are all clamped, the clamp body and the pressure plate clamp the wires through a ...
