Embodiment 2
[0022] On the basis of the above embodiments, in this embodiment, a tungsten alloy steel wire is arranged at the center of the steel rope 4 , and the high tensile strength of the tungsten alloy is used to increase the overall tensile strength of the steel rope 4 .
Embodiment 3
[0024] On the basis of the above-mentioned embodiments, in this embodiment, the most central steel rope 4 is arranged above the insulating layer 1, and the rest are arranged below the insulating layer 1, so that the steel ropes formed in this way present a triangular shape with higher stability .
Embodiment 4
[0026] On the basis of the above embodiments, in this embodiment, the wires 2 of the row are bent into a tower shape at the connection between the central connecting rib 3 and the two sides of the insulating layer 1, which is convenient for construction selection.

The invention discloses a high-reliability large-span steel wire reinforced core bundled overhead line and a processing process thereof. The high-reliability large-span steel wire reinforced core bundled overhead line comprises bunched overhead lines and a reinforced tensile line. The bunched overhead lines comprises four parallel wires; insulating layers are arranged on the surfaces of the wiresin a surrounding mode; connecting ribs are arranged between the insulating layers; the connecting rib in the middle is arranged to be in an arc shape with the convex upper portion and the concave lower portion, and the arc diameter of the connecting rib is consistent with that of the wires; a steel rope is arranged at the connecting rib; an anti-aging layer is arranged on the surface of the steelrope; fixing rings are arranged on the surface of the anti-aging layer at intervals; and the fixing rings are connected with the connecting rib and the insulating layers. According to the scheme, mosttensile stress on the bundled overhead lines is transferred to the steel rope, and the high tensile strength of the tungsten alloy steel is utilized to improve the overall tensile capacity, so that the construction of the whole-span steel wire reinforced core bundled overhead lines is more resistant, and the reliability is higher.
Description
technical field [0001] The invention relates to the field of electric wires and cables, in particular to a high-reliability large-span steel wire reinforced core bundled overhead wire and a processing technology thereof. Background technique [0002] The bundled wire is a new type of cable that connects multiple insulated cables with insulating materials. It is also called a wire bundle. The two insulated cables are compactly connected together. According to the integrated method, there are parallel, flat and square rows. It is a compact cable bundle that works in an overhead manner. Seal between cables. In some canyons or mountain tops with large-span construction, this cable is used. Because it is used for large-span, and the bundled wires are mainly used for power transmission, its tensile strength acts on the wires, which is not convenient for construction. The tensile stress is transferred to a certain extent, which not only facilitates construction but also protects ...
