[0002] High-strength conductor is a kind of power transmission wire made of advanced materials and processes, which is characterized by high tensile strength and load-bearing capacity. The main application areas of high-strength conductors include special occasions such as traction lines, special patrol lines, submarine cables, as well as medium and heavy ice areas, crossing river canyons, hilly areas, forest areas and other environments. In these occasions, high-strength conductors can effectively reduce the number and floor space of towers and increase the span between line towers with their excellent mechanical strength and load-bearing capacity. At the same time, it can also avoid the felling of trees and the demolition of houses, and achieve harmonious coexistence between man and nature. However, the existing high-strength conductors still have shortcomings, such as:

[0003] Announcement No.: CN220189307U A high-strength composite core carbon fiber transmission conductor, which can separate and fix the optical fiber lines through the support bar, which is convenient for the disassembly and assembly of the optical fiber lines. The four optical fiber lines are limited and fixed in the positioning grooves around the support bar, so that the optical fiber lines are limited and fixed between the outer wall of the support bar and the stainless steel tube.

[0026] The fixing block on one side of the connecting block 7 is engaged with the groove at the first connecting piece 3, and then the screw rod 9 is turned to move the connecting rod 10 threadedly connected to the outer surface of the screw rod 9, so that the connecting rod 10 drives the positioning block 11 to move until it forms an engaging structure with the positioning groove 12 at the second connecting piece 4, and the splicing method is faster.
