Embodiment 1

[0022] As shown in the figure, a high-reliability large-span steel wire reinforced core bundled overhead wire includes a bundled overhead wire and a reinforced tensile wire. The bundled overhead wire includes four parallel wires 2, and the surface of the wires 2 is surrounded by insulation. Layer 1, connecting ribs 3 are arranged between insulating layers 1, and the middlemost connecting ribs 3 are set in a convex and concave arc shape, and the arc diameter is set to be consistent with the diameter of the wire 2; The surface of the rope 4 and steel rope 4 is provided with a layer of anti-aging layer 6, and the surface of the anti-aging layer 6 is provided with fixing rings 5 ​​at intervals, and the fixing ring 5 is connected with the connecting rib 3 and the insulating layer 1. In this design, a steel rope 4 is added to the connecting rib 3 of the bundled overhead line to bear the tension as a whole, and the tension on the wire is transferred to the steel rope 4, so that most o...

Embodiment 2

[0024] 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

[0026] 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 .

Abstract

The invention discloses high-reliability large-span steel wire reinforced core bundled overhead wires and its processing technology, including bundled overhead wires and reinforced stretched wires. The bundled overhead wires include four parallel wires, and the surface of the wires is surrounded by an insulating layer. , there is a connecting rib between the insulating layers, the middle connecting rib is set in a convex and concave arc shape, and its arc diameter is set to be consistent with the wire; a steel rope is arranged at the connecting rib, and a layer of steel rope is arranged on the surface of the steel rope. Anti-aging layer, the surface of the anti-aging layer is provided with fixed rings at intervals, and the fixed rings are connected with the connecting ribs and the insulating layer; this scheme transfers most of the tensile stress on the clustered overhead wires to the steel ropes, and uses the tungsten alloy steel High tensile strength is used to improve the overall tensile capacity, making the construction of the entire span steel wire reinforced core bundled overhead line more resistant and more reliable.

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 ...
