Problems solved by technology

Moreover, due to the imbalance of energy distribution and the development of the east and west, it is urgent to solve the bottleneck problem of high-power and 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 aluminum stranded wires, transmission lines have been unable to withstand the rapid expansion of transmission capacity, and power transmission has become a "bottleneck" for the development of the power industry.
[0003] ACSR common aluminum stranded wire has its disadvantages: it cannot operate at high temperature, which limits the capacity of the wire and the current carrying capacity is limited; the steel core is heavy, the coefficient of thermal expansion is large, and the thermal arc sag is large; High tower, high engineering cost
Its defect: the conductor core is made of glass fiber and carbon fiber composite materials, the modulus of the load-bearing core is much smaller than that of the steel core, forming a ...

Abstract

The invention provides a novel wire and an application thereof. The novel wire comprises a force-bearing core, one or more conductor coating layers and a conductor twisting layer from inside to outside in sequence; the fore-bearing core is a special-shaped force-bearing core or special-shaped force-bearing core group; the special-shaped force-bearing core consists of a base material and reinforcefibers and is noncircular; each conductor coating layer is an aluminum, aluminum alloy, copper or copper alloy coating layer; and the conductor twisting layer is an aluminum, aluminum alloy, copper orcopper alloy wire which is wound around the conductor coating layer. By virtue of special structure, design and processing method, the shortcoming of the existing carbon fiber wire can be solved.

Description
