(Summary description)Carbon fiber composite core wire is another model of contemporary technological development. It is a new type of wire developed using the high strength and corrosion resistance of carbon fiber. Compared with the conventional steel core aluminum stranded wire, it has a series of advantages such as light weight, high tensile strength, high temperature resistance, corrosion resistance, large current carrying capacity, and low line loss.

The carbon fiber composite core wire has a higher transport capacity, and its current carrying capacity can reach twice that of conventional wires under the same weight. Carbon fiber composite core conductors use soft aluminum with less wire loss instead of hard aluminum for twisting. There are no magnetic losses and thermal effects caused by steel wire materials, which can greatly reduce power transmission losses. The heat resistance of this product is much higher than that of steel core wire, and it can run at 160 degrees high temperature to meet the needs of peak power consumption. Compared with carbon fiber composite core wire and steel core aluminum stranded wire of the same weight, the aluminum cross section can be increased by 10-35%. No need to rebuild the tower to re-establish new lines to increase capacity.

The tensile strength of general steel wires is 1240 MPa, while the strength of carbon fiber composite cores can reach more than 2400 MPa, and the strength safety factor of carbon fiber composite core wires is nearly doubled.

Carbon fiber composite core wire has a small coefficient of linear expansion, eliminates line sag, is not affected by long-term creep of aluminum, and avoids thermal expansion sag of traditional steel core cables. It can reduce the height of pole towers, increase the distance between poles and towers, and reduce more than 16% of towers and poles, thereby reducing transmission line corridors, saving land resources and reducing the overall construction cost of transmission lines. This makes it not only have a strong comprehensive benefit advantage in the reconstruction of the old line; even in the construction of the new line, it also has a competitive advantage.
