Description

A kind of railway combined through ground wire
Technical field
The utility model is related to field of cable technology more particularly to a kind of railway combined through ground wire.
Background technology
Railway combined through ground wire in the prior art, structure generally comprises cable core and semiconductive plastic sheath or lead closes Golden sheath.Aerial drainage is unsmooth in application process for conductor plastic sheath type ground wire, is easy to happen fire;And signal shielding performance Bad, cable integrally bending performance and electric conductivity are bad.Lead content is exceeded in lead alloy sheath, pollutes environment.Acidproof simultaneously, Alkali, salt corrosion, sulfur dioxide corrosion and salt air corrosion performance etc. cannot meet the needs of railway construction, the matter of these products Amount is directly related to the safety of railway transportation and generates human life's property loss;It is subject to acid, alkali, salt corrosion, two simultaneously Sulfur corrosion and salt air corrosion are aoxidized, there is also stomata, slag inclusion, sand holes, inclined the defects of welding crackle, shadows at jacket surface soldered Ring product quality and safety of railway traffic.
Utility model content
Utility model aims to solve above-mentioned prior art problems, and the railway combined perforation ground of the one kind provided Line.
A kind of railway combined through ground wire, including insulated wire cores, belting layer and alloy protective jacket layer;The insulated wire cores be by Fluorine silicone rubber insulating layer extrudes copper free wire conductor and forms, and is provided on the outside of a centrally located insulated wire cores and is insulated by the six roots of sensation The second layer structure that core is constituted;It is provided with the third layer structure being made of 12 insulated wire cores outside six roots of sensation insulated wire cores, three Layer insulated wire cores are wrapped at cable core by belting layer;It is provided with metal armor layers outside the belting layer;Outside the metal armor layers It is provided with insulation woven shield;It is provided with alloy sleeve layer outside the shielded layer.
Further, one group of aerial drainage line is symmetrically arranged in the metal armor layers.
Further, the alloy protective jacket layer is compo pipe made of continuous drawing.
Further, the twisted lay ratio of the second layer structure is 14~16 times, the lay ratio of the second layer structure It is 12~14 times;Three-layer insulated core is twisted using pre- back twist.
The beneficial effects of the utility model:The structure design of the utility model is reasonable, and alloy protective jacket layer is seamless to be coated on cable core Outside overcomes stomata, slag inclusion, sand holes, welds partially the defects of crackle, the whole close, surface-brightening of cable core;Twisted pitch diameter compares Small, cable integrally bending performance and electric conductivity are promoted;Advantages of good shielding performance, excellent electrical properties have fire retardant performance;And And corrosion resistance greatly improves, service life can improve 3-5, ensure the safety of railway transportation and the peace of human life Entirely.
Description of the drawings
Fig. 1 is the utility model schematic cross-sectional view.
Wherein:1, insulated wire cores;2, belting layer;3, metal armor layers;4, shielded layer;5, alloy protective jacket layer;6, aerial drainage line.
Specific implementation mode
The utility model is described in further detail for embodiment in below in conjunction with the accompanying drawings, but does not constitute to this reality With novel any restrictions.
Refering to Figure 1, a kind of railway combined through ground wire, including insulated wire cores 1, belting layer 2 and alloy protective jacket layer 5;The insulated wire cores 1 are to extrude copper free wire conductor by fluorine silicone rubber insulating layer to form, a centrally located insulated wire cores 1 Outside is provided with the second layer structure being made of six roots of sensation insulated wire cores 1;It is provided with by 12 insulated wires outside six roots of sensation insulated wire cores 1 The third layer structure that core 1 is constituted, three-layer insulated core are wrapped at cable core by belting layer 2;It is provided with metal outside the belting layer 2 Armor 3;Insulation woven shield 4 is provided with outside the metal armor layers 3;It is provided with alloy sleeve layer outside the shielded layer 4 5.One group of aerial drainage line 6 is symmetrically arranged in the metal armor layers 3.The alloy protective jacket layer 5 is alloy made of continuous drawing Pipe;Integral seamless is coated on outside cable core, is overcome stomata, slag inclusion, sand holes, is welded the defects of crackle partially;And corrosion resistance is big Big to improve, service life can improve 3-5.The twisted lay ratio of the second layer structure is 14~16 times, the second layer The lay ratio of structure is 12~14 times;Three-layer insulated core is twisted using pre- back twist;Whole pre- back twist, twists in stranding process Close single line even tension;The whole close, surface-brightening of cable core;Twisted pitch diameter is smaller, cable integrally bending performance and aerial drainage It can get a promotion;Advantages of good shielding performance, excellent electrical properties have fire retardant performance.
Preferred embodiments of the present invention described in detail above, but the utility model is not limited to above-mentioned implementation Detail in mode can carry out the technical solution of the utility model in the range of the technology design of the utility model A variety of equivalents, these equivalents belong to the scope of protection of the utility model.
