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 wires have poor wind resistance and large galloping range

Abstract

The invention relates to a low-swinging carbon fiber composite core photoelectric composite overhead conductor which sequentially comprises a stainless steel optical unit, a carbon fiber composite core and a duralumin molded line outer layer from inside to outside. The stainless steel optical unit is composed of a plurality of optical fibers which are arranged in a stainless steel protection pipe. The carbon fiber composite core is a high-strength conductive composite material composed of epoxy resin, nanometer expanded graphite with the expansion multiple more than 100 and reinforcing carbon fibers. Spiral surrounding stripes are arranged on the outer contour of the duralumin molded line outer layer. Compared with the prior art, the low-swinging carbon fiber composite core photoelectric composite overhead conductor has the advantages of being good in softening performance and improving tensile strength. Meanwhile, the spiral surrounding stripes are arranged on the outer contour of the duralumin molded line outer layer, and therefore reduction of swinging 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...
