Description

Steel core filling epoxy resin takes out a strand type expanded diameter conductor

Technical field

The utility model belongs to electric power technical field of transportation, and in particular to it is expanding that a kind of steel core filling epoxy resin takes out strand type Wire.

Background technology

For taking out stock containing what corrosive elements area was set up in general occasion especially air heavily contaminated area and air Type expanded diameter conductor, although there is a protection of zinc coat on steel wire surface, but can still occur in 18 years or so even shorter time Rust staining, then has a single line to break from surface to internal progressively corrosion steel wire up to steel wire breakage is lost in function, steel strand wires Stress concentration will occur here after splitting and ultimately result in the destruction of whole wire；How more effectively to avoid, suppress or prolong The appearance of slow steel strand wires rust staining, makes the load-bearing component in this wire of steel strand wires to stablize in the whole life cycle of wire Reliably play a role, it appears most important；Be effectively reduction wire erection environment in air contained by corrosion composition to leading The erosion of line steel core, so as to avoid environmental corrosion from running the potential safety hazard brought and service life shortening to wire, it is necessary to adopt With more positive defensive measure, to reduce influence of the overhead transmission line caused by environmental corrosion factor to greatest extent.

Utility model content

In order to solve the above technical problems, the purpose of this utility model is to propose that a kind of steel core filling epoxy resin is taken out strand type and expanded Footpath wire.

The utility model adopts the following technical scheme that to complete above-mentioned purpose：

A kind of steel core filling epoxy resin takes out a strand type expanded diameter conductor, and the center of the steel-cored aluminium strand has by many steel lists The steel strand wires of line coiling；Epoxy resin, and two neighboring described steel list are coated with the surface of the every steel single line Epoxy resin is filled between line；The outside of the steel strand wires, which is dredged, is wound with dredging around aluminum steel stranded layer as conducting element；It is described Dredge at least one layer of around aluminum steel stranded layer；The thin outside solid matter around aluminum steel stranded layer is wound with one layer of solid matter winding aluminum steel and twisted Layer is closed, the direction of lay of the solid matter winding aluminum steel stranded layer is dextrad, it is adjacent thereto described thin around the stranded of aluminum steel stranded layer Direction is left-hand, and the thin direction of lay around aluminum steel stranded layer described in adjacent two layers is opposite.

The utility model proposes a kind of steel core filling epoxy resin take out a strand type expanded diameter conductor, equably filled out by epoxy resin Fill and be coated at steel strand wires internal voids and surface, play a part of protecting steel strand wires from environmental corrosion；Avoid general Environmental corrosion is to wire performance when being set up in occasion especially air heavily contaminated area and air containing corrosive elements area Influence, more effectively protects steel core, the service life of wire greatly improved.

Brief description of the drawings

Fig. 1 the utility model structural representations.

In figure：1st, steel strand wires, 2, epoxy resin, 3, dredge around aluminum steel stranded layer, 4 solid matters winding aluminum steel stranded layer.

Embodiment

The utility model is illustrated with reference to the drawings and specific embodiments：

As shown in figure 1, a kind of steel core filling epoxy resin takes out a strand type expanded diameter conductor, it is described to take out a burst center for type expanded diameter conductor With the steel strand wires 1 by many steel single line coilings；Epoxy resin 2, and adjacent two are coated with the surface of every steel single line Epoxy resin 2 is filled between individual steel single line；The outsides of the steel strand wires 1 dredge be wound with as support and conducting element dredge around Aluminum steel stranded layer 3；Described dredging is at least one layer of around aluminum steel stranded layer 3, can be two layers；In the embodiment, described dredges around aluminium Line stranded layer 3 is two layers；There is one layer of solid matter winding aluminum steel stranded layer 4 around the outside of aluminum steel stranded layer 3 dredging.Wire is outermost The direction of lay of solid matter winding aluminum steel stranded layer 4 is dextrad, and inwardly adjacent layer direction of lay is opposite successively.

The steel strand wires 1 are formed by steel wire single line is stranded.

The epoxy resin filling 2, is filled uniformly with by epoxy resin and is coated in the internal voids of steel strand wires 1 and surface Place, plays a part of protecting steel strand wires 1 from environmental corrosion.Epoxy resin has good physics, chemical property after hardening, Its surface to metal and nonmetallic materials has excellent adhesive strength, and dielectric properties are good, and deformation retract rate is small, product chi Very little good stability, hardness is high, pliability preferably, to alkali and most of solvent-stable, epoxy resin as anticorrosive not only With closely knit, water resistant, anti-leakage is good, intensity is high the features such as, while having adhesive force strong, normal-temperature operation, easy construction etc. good Manufacturability, it is and moderate.

Described dredge belongs to new steel core ring type filling oxygen tree fat around aluminum steel stranded layer 3 and takes out burst support of type expanded diameter conductor and a conduction Element, can be new steel core ring type filling oxygen tree while conduction with certain tensile strength and preferable electric conductivity Fat steel-cored aluminium strand provides axial tensile capacity to improve the overall tension of new steel core ring type filling oxygen tree fat steel-cored aluminium strand Intensity, electric conductivity is superior, and conductance reaches 61%IACS.It is conventional preferable aerial condutor conductor material.

The solid matter winding aluminum steel stranded layer 4 belongs to new steel core ring type filling oxygen tree fat and takes out a burst conductive element for type expanded diameter conductor Part, with certain tensile strength and preferable electric conductivity, conductance reaches 61%IACS.It is that conventional preferably making somebody a mere figurehead is led Line conductor material.
