Abstract
The invention relates to an extrusion-type transparent plastic coated wire comprising a middle core bundle and a plastic coated outer layer. The middle core bundle and the plastic coated outer layer are a tubular structure respectively; the middle core bundle is sheathed in the plastic coated outer layer; a lining layer is arranged between the middle core bundle and the plastic coated outer layer; the middle core bundle is formed by mutually stranding at least two conductor wire strands; the plastic coated outer layer is made of transparent plastics or semi-transparent plastics; the production mode of plastic coated outer layer is an extrusion-type production mode; the manufacturing raw material of the lining layer is epoxy resin or polrvinyl chloride; the conductor wire strands are formed by stranding at least two copper alloy wires; and the manufacturing raw materials of the copper alloy wires are copper-silver alloys, copper-magnesium alloys, copper-tin alloys or copper-aluminum alloys. The invention not only has stronger abrasion resistance, higher insulation strength but also has higher mechanical strength and stronger toughness.
Description
Technical field
The present invention relates to a kind of plastic line, relate in particular to the transparent plastic line of a kind of squash type, specifically be applicable to power supply department high-voltage earthing connecting line usefulness.
Background technology
The plastic line that uses mostly is double-decker at present, and internal layer is a plain conductor, and skin is an insulating barrier, carries out matched in clearance to constitute plastic line by plain conductor and insulating barrier then.This kind structure has been ignored the friction between plain conductor and the insulating barrier, in the use, the situation that plain conductor is insulated the inner surface friction fracture of layer usually takes place, and the manufactured materials of plain conductor commonly used is a copper at present, though can guarantee good electrical conductivity, the price comparison height, production cost is bigger, in addition, the mechanical strength of plain conductor is lower in the prior art, fractures easily during use.
Summary of the invention
The objective of the invention is to overcome exist in the prior art easy to wear, defective and problem that mechanical strength is lower, provide a kind of squash type not easy to wear, that mechanical strength is higher transparent plastic line.
For realizing above purpose, technical solution of the present invention is: the transparent plastic line of a kind of squash type, comprise intermediate core bundle and plastic skin, and described intermediate core bundle and plastic skin are tubular structure, and plastic outer field internal sleeve is equipped with the intermediate core bundle; Be provided with inner covering between described intermediate core bundle and the plastic skin, and the intermediate core bundle is by mutual stranded the forming of at least two bursts of conductive strand.
Described plastic skin is transparent or semitransparent material, and its mode of production is squash type production.
Described plastic outer field manufactured materials is PE plastics, PVC plastics, polyethylene or polypropylene.
Described PVC plastics are PVC blood transfusion liquid pellet.
The manufacturing raw material of described inner covering is epoxy resin or polyvinyl chloride.
Described conductive strand is by at least two stranded forming of copper alloy wire.
The quantity of described conductive strand is 19 strands, and the quantity of copper alloy wire is 16,27,42,58 or 84.
The quantity of described conductive strand is 12 strands, and the quantity of copper alloy wire is 42 or 63.
The quantity of described conductive strand is 7 strands, and the quantity of copper alloy wire is 63 or 68.
The manufacturing raw material of described copper alloy wire is Kufil, copper magnesium alloy, signal bronze or albronze.
Compared with prior art, beneficial effect of the present invention is:
1. because the transparent plastic line of a kind of squash type of the present invention comprises intermediate core bundle, inner covering and plastic skin from inside to outside successively, the existence of inner covering has separated intermediate core bundle and plastic skin, effectively avoided the intermediate core bundle to be taken place by the situation of plastic outer wear and rupture, and plastic outer field manufactured materials is PE plastics, PVC plastics, polyethylene or polypropylene, the manufacturing raw material of inner covering is epoxy resin or polyvinyl chloride, not only have good resistance to wear, and insulation effect is better.Therefore the present invention is not easy to wear, and insulation effect is better.
2. owing to the intermediate core bundle in the transparent plastic line of a kind of squash type of the present invention forms by the multiply conductive strand is stranded, and per share conductive strand is by many stranded the forming of copper alloy wire, has stronger toughness, in addition, the manufactured materials of copper alloy wire is Kufil, copper magnesium alloy, signal bronze or albronze, the range of choice broad, applicability is stronger.Therefore mechanical strength of the present invention is higher, and toughness is stronger.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: intermediate core bundle 1, plastic outer 2, inner covering 3, conductive strand 4, copper alloy wire 5.
Embodiment
The present invention is further detailed explanation below in conjunction with description of drawings and embodiment
Referring to Fig. 1, the transparent plastic line of a kind of squash type, comprise intermediate core bundle 1 and plastic outer 2, intermediate core bundle 1 is tubular structure with plastic outer 2, and plastic outer 2 internal sleeve is equipped with intermediate core bundle 1, special feature of the present invention is to be provided with inner covering 3 between intermediate core bundle 1 and plastic outer 2, and intermediate core bundle 1 is by at least two bursts of conductive strand 4 mutual stranded forming.
Preferred plastic outer 2 is transparent or semitransparent material, and its mode of production is squash type production; Plastic outer 2 manufactured materials is PE plastics, PVC plastics, polyethylene or polypropylene, and wherein the PVC plastics are preferably PVC blood transfusion liquid pellet.
The manufacturing raw material of preferred liner layer 3 is epoxy resin or polyvinyl chloride.
Preferred conductive strand 4 is by at least two copper alloy wires 5 stranded forming, and wherein the quantity of conductive strand 4 is 19 strands, and the quantity of copper alloy wire 5 is 16,27,42,58 or 84; Or the quantity of conductive strand 4 is 12 strands, and the quantity of copper alloy wire 5 is 42 or 63; Or the quantity of conductive strand 4 is 7 strands, and the quantity of copper alloy wire 5 is 63 or 68; The manufacturing raw material of copper alloy wire 5 is Kufil, copper magnesium alloy, signal bronze or albronze.
