Carbon fiber overhead conductor with optical fiber communication function

Abstract

The invention discloses a carbon fiber overhead conductor with an optical fiber communication function. The carbon fiber overhead conductor comprises a carbon fiber composite material core, an opticalfiber structure, an inner aluminum layer, a middle aluminum layer wrapping the inner aluminum layer and the optical fiber structure, and an outer aluminum layer. The optical fiber structure comprisesan aluminum alloy pipe, heat insulation cotton and an optical fiber. According to the invention, the optical fiber structure and the inner aluminum layer are twisted together to coat the carbon fibercomposite material core. Meanwhile, the functions of electric conduction and communication are achieved, the time and cost required by line erecting are saved, the inner aluminum layer and the optical fiber structure are wrapped by the aluminum layer in use, the composite carbon fiber material core is protected against corrosion caused by weather such as external acid rain and saline-alkaline fog, the bending resistance of the wire is improved, and optical fibers can be protected advantageously. The carbon fiber composite overhead conductor has the advantages of a carbon fiber conductor, optical fiber communication and transmission of data such as conductor voltage, current, operating temperature and tension can be achieved, and real-time monitoring of the operating state of the overheadconductor is facilitated.

Description

technical field [0001] The invention relates to the field of overhead wires, and discloses a carbon fiber overhead wire with optical fiber communication function. Background technique [0002] At present, steel-cored aluminum stranded wires are mostly used in domestic overhead conductors, which have the advantages of mature technology and low price, but low operating temperature, low ampacity, heavy weight, large land use, and a large amount of iron towers. Compared with the steel-reinforced aluminum stranded wire, the strength of the carbon fiber composite material core is about 1.5 times that of the steel core, and the density is about 0.25 times that of the steel core. times. Due to the high price of carbon fiber composite cores, they are not widely used in the field of overhead conductors. They are mainly used for capacity expansion of old lines. However, with the development of carbon fiber technology, their prices will become lower and lower. In the future, there will...

Problems solved by technology

[0003] The practical application of carbon fiber wires shows that because the wires are exposed to harsh environments such as acid rain and saline fog for a long time, the surface of the carbon fiber composite material core will age, which will affect the service life of the wires.
