Triangular carbon fiber photoelectricity composite overhead conductor

Abstract

The invention relates to a triangular carbon fiber photoelectricity composite overhead conductor which comprises a photoelectricity composite structure and a high temperature resistant insulation material layer, wherein the photoelectricity composite structure is composed of a carbon fiber strength bearing part, a stainless steel optical unit and duralumin round lines. The cross section of the high temperature resistant insulation material layer is triangular, each corner of the triangular cross section contains one duralumin round line, the center of the cross section of the high temperature resistant insulation material layer contains the carbon fiber strength bearing part, and the stainless steel optical unit is contained in the gap among the duralumin round lines and the carbon fiber strength bearing part in the high temperature resistant insulation material layer. Compared with the prior art, the triangular carbon fiber photoelectricity composite overhead conductor has the advantages of being good in soft property and improved in strength of extension, meanwhile, the windage resistance of the triangular cross section is smaller than that of a round section, and therefore the reduction of waving of the overhead conductor is facilitated.

Description

technical field [0001] The invention relates to the field of wires and cables, in particular to power transmission and power communication systems, especially a carbon fiber composite core double-capacity power optical cable with dual functions of power transmission and optical communication for urban and rural distribution network systems. [0002] Background technique [0003] With the rapid development of my country's economy, the obvious acceleration of urban modernization, the continuous expansion of urban scale and the rapid development of new rural construction, the demand for electricity has grown rapidly. Moreover, due to the imbalance in energy distribution and the development of the east and west, it is urgent to solve the bottleneck problem of high-power, long-distance energy transmission. Although the construction of ultra-high voltage has partially alleviated this contradiction, due to the limitation of the carrying capacity of traditional steel-reinforced alu...

Problems solved by technology

[0012] Although the carbon fiber wire has many advantages above, it cannot realize the communication function, and another communication line is needed to meet the communication function, resulting in repeated wiring

In addition, the existing circular cross-section conductors have poor wind resistance and large galloping range
