Problems solved by technology

The disadvantage of this wire is that it cannot maximize the flow per unit section, because the current is easy to flow through the outer surface of the conductor, and the flow in the center is very small. The structure of this wire not only increases the resistance but also wastes a lot of conductors. materials, and does not comply with the natural law of current skin effect

Abstract

The invention belongs to the field of electric engineering of transmission lines and in particular relates to a heat-resistant transmission conductor for the transmission line. The transmission conductor comprises a steel core, a metal conductive medium layer coating the steel core, and an outer insulating layer coating the metal conductive medium layer, wherein an insulating material is filled between the steel core and the metal conductive medium layer; the metal conductive medium layer is a hollow conductor; and a tensile reinforcement through which the hollow conductor is divided into twosemicircular spaces is arranged in the hollow conductor. The transmission conductor provided by the invention has the advantages that the conductor part is a heat-resistant aluminum alloy and has a function of bulking the conductor, so that the transmission conductor has high current-carrying capacity; and moreover, the conductor has a hollow shape, and the steel core is coated by the center of the conductor, so that the strength of the transmission conductor is improved, the contact surface of the conductor is large, the resistance is reduced, and the electric conductivity is high; and therefore, the transmission conductor conforms to a natural law of a skin effect of the current.

Description

technical field [0001] The invention belongs to the field of electrical engineering of transmission lines, and in particular relates to a heat-resistant transmission wire for transmission lines. Background technique [0002] As the final form of energy transformed from various energy sources, electric energy serves human society and becomes an essential element of production and life in human life. Electric energy is usually generated by power generation places such as hydropower stations, thermal power stations, and wind farms. In order to make full use of electric energy, it is necessary to continuously transmit electric power to places where electric power is demanded. Human beings have entered the information age, and their dependence on electricity is becoming more and more serious. Not only large-scale industries require a lot of electricity, but also electricity for home office lighting, various communication equipment, and information equipment that carries a large a...
