Description

A twisted carbon fiber wire

technical field

The utility model relates to the technical field of carbon fiber wires, in particular to a stranded carbon fiber wire.

Background technique

Compared with traditional wires, carbon fiber wires have advantages in energy saving, land saving, material saving, environmental protection and improving power transmission capacity. The inherent characteristics of carbon fiber conductors determine that they are different from ordinary steel-reinforced aluminum strands in the construction process. Ordinary steel-cored aluminum stranded wire is the steel core that bears the tension, while the part of the carbon fiber wire that bears the tension is the carbon fiber composite core, which is easy to break and brings hidden dangers to the normal operation of the line.
