Abstract
The invention provides an overhead power transmission conduction wire, which has the advantages of easy manufacturing and processing, low manufacturing cost and high diameter-expanding rate. The overhead power transmission conduction wire comprises a steel core and an aluminum wire, wherein the steel core is arranged at the central position of the most inner layer, and the aluminum wire is arranged outside the steel core and consists of a plurality of aluminum single wires intertwisted together. The overhead power transmission conduction wire further comprises one or more supporting pieces which are made of a non-metallic material and are arranged outside the steel core. The supporting pieces are made of one or more of high density polyethylene, PVC, plastic, nylon or paper-characteristic materials. The shape of the aluminum single wires is one of roundness, Z shape, arch, sector and human head shape. The overhead power transmission conduction wire uses the supporting pieces to easily have the effect of expanding the diameter, has unlimited diameter-expanding rate, causes no problems of construction wire jumpers and the like, and is convenient for production-manufacturing.
Description
Technical field
The present invention relates to a kind of overhead power transmission conducting wire, belong to the overhead power transmission conducting wire technical field.
Background technology
Overhead power transmission conducting wire generally adopts steel reinforced aluminium conductor or steel core aluminium alloy stranded conductor, wherein the steel core made of galvanized steel wire or aluminium-clad steel wire is as the load part, the aluminum or aluminum alloy line is current-carrying part, and the structure of lead is that steel core is arranged in the innermost layer, and aluminum or aluminum alloy line strand is in the outside of steel core.
Transmission line capability requires the metal wire of conduction that corresponding cross-sectional area should be arranged, when transmission line is in the high-voltage operation state or during in the operation of the geographical position of higher height above sea level, corona and noise appear in lead easily, cause energy loss and environmental pollution, and the diameter that increases lead is conducive to alleviate these phenomenons.
When the diameter of wire that is moving is big inadequately, just must increase its diameter, can adopt the sectional area of the aluminum or aluminum alloy that increases steel core or conduction usually, or increase both sectional areas simultaneously, increase the diameter of lead (or bus).But said method all need increase metal material, has also just increased the weight of lead, has increased the burden of iron tower, thereby has also increased the circuit gross investment.
In order to address this problem, mainly adopted dual mode in the past, a kind of is to adopt the hole enlargement mode of dredging around formula, mainly be in original normal lay configuration, to extract some strands of single lines out to play the hole enlargement purpose, the shortcoming of this kind hole enlargement mode is that enlarging rate is restricted, might cause defectives such as construction wire jumper; The opposing party's mode is that the tubular supporting piece that utilizes electric conducting material to make comes hole enlargement, and the shortcoming of this hole enlargement mode is relatively difficulty of stay pipe processing and manufacturing that hole enlargement uses, and expense is higher, and lead is not flexible.
Summary of the invention
The objective of the invention is to overcome defective of the prior art, provide a kind of manufacturing processing than being easier to, cost is low, the overhead power transmission conducting wire that enlarging rate is high.
For achieving the above object, the present invention adopts following technical scheme:
A kind of overhead power transmission conducting wire, comprise steel core, aluminum steel, steel core be arranged in the lead innermost layer at the center, aluminum steel is arranged on the outside of steel core, aluminum steel constitutes by many aluminium single lines are stranded, overhead power transmission conducting wire also comprises one or more by the strutting piece that nonmetallic materials are made, and described strutting piece is arranged on the outside of steel core.
Strutting piece can be made by in high density polyethylene (HDPE) (HDPE, high density polyethylene is hereinafter to be referred as HDPE), PVC, plastics, nylon or the paper material one or more.Aluminium single line shape can be in circular, Z-shaped, arch, fan-shaped, the people's capitiform a kind of.
Strutting piece can for the identical list structure of aluminium single line shape, strutting piece and aluminium single line twist together.
Strutting piece can be many hollow tubular things or solid cylinder thing.6-18 root strutting piece twists outside steel core and is made as one or more layers supporting layer.The aluminium single line is positioned at the outside of strutting piece.
Strutting piece can be the supporting layer of a hollow tubular thing formation, and strutting piece with the steel core parcel wherein.Can there be the groove structure inside of strutting piece or outside.The aluminium single line is positioned at the outside of strutting piece.
The invention provides and a kind ofly be twisted into the overhead power transmission conducting wire of supporting layer with backing material or by molded lines, utilize strutting piece can be relatively easy to play the hole enlargement effect, enlarging rate is unrestricted, can not cause problems such as construction wire jumper, manufactures easy.

Embodiment
As shown in Figure 1, strutting piece 3 can be shape and aluminium single line 2 identical or similar bars, it is stranded to utilize strutting piece 3 instead of part unlined aluminium single lines 2 and other aluminium single lines 2 to carry out, and makes the conductor of regular lay configuration, and strutting piece 3 can be made by materials such as HDPE, PVC, plastics, nylon, paperys; Outer aluminium single line 2 can adopt molded lines such as circular single line or Z type, arch, fan-shaped, people's capitiform.
As shown in Figure 2, strutting piece 3 can be the hollow tubular thing that materials such as HDPE, PVC, plastics, nylon are made, and 6～18 hollow tubular thing single or multiple lifts are twisted outside steel core 1; To play the effect with steel core 1 location and hole enlargement; But those hollow tubular thing solid matters are stranded, also can loose arrangement; Outer aluminium single line 2 can adopt molded lines such as circular single line or Z type, arch, fan-shaped, people's capitiform.
As shown in Figure 3, extrude materials such as certain thickness HDPE, PVC, plastics, nylon as strutting piece 3 outside steel core 1, strutting piece 3 constitutes supporting layer, to play the effect with steel core 1 location and hole enlargement; As shown in Figure 4, this supporting layer also can slot 4, and concrete groove shape is not limit, and the main purpose of fluting is in order to reduce the consumption of supporter, to reduce cost and to reduce wire weight; Outer aluminium single line 2 can adopt molded lines such as circular single line or Z type, arch, fan-shaped, people's capitiform.
