For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
In power line according to the utility model embodiment, comprise inner wire 1, insulator 2, intermediate layer 3, outer conductor 4 and sheath 5 from inside to outside successively, as shown in Figure 1.Inner wire 1 inner wire 1 is made up of many copper cash usually, and radical determines jointly that by copper cash line footpath and inner wire sectional area copper cash generally adopts naked copper or tin-coated copper; Insulator 2 is generally polyethylene (PE), polyvinyl chloride (PVC), low-smoke halogen-free polyolefin (LSZH) or thermoplastic elastomer; Inner wire 1 is formed heart yearn with insulator 2, and heart yearn is formed by 2 usually.Sheath 5 is processed by polyethylene (PE), polyvinyl chloride (PVC), low-smoke halogen-free polyolefin (LSZH) or thermoplastic elastomer usually; Intermediate layer 3 both can be provided with also and can not be provided with, and when being provided with intermediate layer 3, if adopt aluminium foil, then as outer conductor or screen, if select PET film (or polyester film) for use, then played the effect of isolating and protecting.Wherein, outer conductor 4 is formed by the mixed weaving line braiding that multiply comprises tin-coated copper recombination line and zinc-plated copper-clad light metal conductor recombination line.Wherein, tin-coated copper recombination line and zinc-plated copper-clad light metal conductor recombination line are with equal number braided outer conductor 4, and zinc-plated copper-clad light metal conductor recombination line is tin-coated copper plated aluminium recombination line and/or tin-coated copper plated aluminium magnesium recombination line.
Though the tin-coated copper plated aluminium recombination line is lower, in light weight than the cost of tin-coated copper plated aluminium magnesium recombination line, tensile strength is not as good as the tin-coated copper plated aluminium magnesium recombination line.Therefore when tin-coated copper recombination line and tin-coated copper plated aluminium recombination line were carried out mixed weaving with formation outer conductor 4, difficulty of processing was relatively large.And, find that through test the tensile strength of tin-coated copper plated aluminium magnesium recombination line and elongation and tin-coated copper recombination line are very approaching, so zinc-plated copper-clad light metal conductor recombination line preferably uses the tin-coated copper plated aluminium magnesium recombination line in the utility model.
In the mixed weaving process, still keep the advantage that good conductivity, low inductance, bending resistance can be good in order to make power line, the alternative ratio of zinc-plated copper-clad light metal conductor recombination line is a key factor.Existing is example with the mixed weaving line that preferably comprises tin-coated copper recombination line and tin-coated copper plated aluminium magnesium recombination line, and wherein per share mixed weaving line has 4 recombination lines.Find through test; When the ratio of tin-coated copper recombination line in the mixed weaving line and tin-coated copper plated aluminium magnesium recombination line is 3: 1; Be the substitution rate of tin-coated copper plated aluminium magnesium recombination line when low, though power line still can keep the original excellent performance and can show substitution effect, substitution effect is not obvious especially; Be that cost changes not quite, and the deadweight of power line especially obviously alleviate.
When the ratio of tin-coated copper recombination line in the mixed weaving line and tin-coated copper plated aluminium magnesium recombination line is 1: 3; Be that the substitution rate of tin-coated copper plated aluminium magnesium recombination line is when higher; Though weight reduction; But because the copper major part in the outer conductor is substituted by magnalium, the shielding properties of power line finished product reduces, loss raising and bending resistance can weaken etc., has weakened the original excellent performance.On the other hand, because the extension performance of magnalium and tensile strength are not so good as copper, after the tin-coated copper plated aluminium magnesium recombination line substituted the tin-coated copper recombination line greatly ratio, the braiding difficulty in the processing improved, and relatively was difficult to completion processing smoothly usually.
When the ratio of tin-coated copper recombination line in the mixed weaving line and tin-coated copper plated aluminium magnesium recombination line is 2: 2, when promptly the quantity of two kinds of recombination lines is identical, find in the test to be easy to braiding in the processing, and the finished product power line still can keep existing various premium properties.Therefore the tin-coated copper recombination line in the mixed weaving line is identical with the quantity of zinc-plated copper-clad light metal recombination line in the utility model.
In addition; The light metal conductor also is a key factor to the alternative ratio of copper in the zinc-plated copper-clad light metal conductor recombination line; After the light metal instead of copper, should keep the various premium properties relevant, but also will realize weight reduction and be easy to processing with copper product.Find that through test in the embodiment of the utility model, the volume ratio of copper and light metal is 1: 9～2: 8 in the zinc-plated copper-clad light metal conductor recombination line.When light metal was preferably magnalium, the preferred volume ratio of copper and magnalium was 3: 17 in the tin-coated copper plated aluminium magnesium recombination line.
