Embodiment Construction
[0059] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0060] The mechanical properties of carbon fiber composite core conductors are different from ordinary steel-reinforced aluminum stranded wires, which are determined by their material properties. The linear expansion coefficient of the carbon fiber composite core is 2.0×10-6 / ℃, the linear expansion coefficient of the steel core is 11.5×10-6 / ℃, and the linear expansion coefficient of the aluminum wire is 23×10-6 / ℃. The linear expansion coefficient of the carbon...
