1kv aluminum-core overhead cable

Abstract

The invention discloses a 1kv aluminum-core overhead cable, which comprises two parallel and vertical cables with the same structure, and the two cables are connected by a plurality of connecting ribs; the cables include a cable core, an extruded The outer sheath outside the cable core and the plastic cooling pipe arranged outside the outer sheath, the cable core is composed of a carbon fiber wire and two aluminum wires arranged parallel and symmetrically on both sides of the carbon fiber wire. The invention has the advantages of aging resistance, corrosion resistance, water vapor resistance, superheated water resistance, electrical insulation performance, good heat dissipation and the like.

Description

technical field [0001] The invention relates to the field of power cables, in particular to a 1kv aluminum-core overhead cable. Background technique [0002] At present, with the development of society, the demand for cables continues to rise, and people's requirements for cables are also getting higher and higher, especially in the environment of overhead cables, when the cables are subjected to external stress, the internal wires are prone to displacement. The local temperature of the cable is too high, which affects the communication effect of the cable; the heat dissipation effect of the existing cable is poor, and the heat generated by the conductor cannot be effectively dissipated during the working process of the cable, resulting in an excessive temperature of the conductor, resulting in a decrease in its carrying capacity . [0003] In the application of long-distance power transmission, under normal circumstances, the above-ground part usually uses steel-cored alum...

AI Technical Summary

Problems solved by technology

In the prior art, steel-cored aluminum strands are used instead of ordinary steel wires, because the tensile strength of ordinary steel wires is relatively small, and even high-strength steel wires cannot reach the tension between long-distance erected cables

In addition, the overhead span is limited and the overhead scale is large, which not only increases the cost, but also has poor resistance to external wind and rainy weather. If it encounters thunderstorms and strong winds, as well as hail and ice, it is prone to fracture and cause accidents
