Abstract
The invention discloses a connection cable of a railway transponder. A conductor is covered by an insulation layer to form an insulation cable core, two or four insulation cable cores are twisted together, then a layer of wrapping tape layer is wound outside the cable cores, and a shielding layer and a restrictive coating layer are packaged outside the wrapping tape layer in sequence. According to the connection cable of the railway transponder, the tinned wires of the materials of a metal braided shield layer are replaced by aluminium magnesium alloy wires, and cost is reduced. The normal polyethylene materials of the restrictive coating layer is replaced by elastoplastics materials with excellent performance, a cable shield is enabled to be softer, and meanwhile the mechanical strength of the cable, the abrasion performance of mechanical and physical property are improved, and the environment resistant and chemical resistant performances of the cable are further improved.
Description
Technical field
The present invention relates to technical field of electric wires and cables, relate in particular to a kind of railway transponder stube cable.
Background technology
Railway transponder stube cable is mainly used in the two ends, station, is arranged on the open air, and environment for use is more abominable.Railway transponder stube cable of the prior art is to consist of insulated wire cores by conductor and polyethylene layer, then thoroughly does away with the stranded rear wrapped nonmetal bands of edge core, tinned wird woven shield, pe sheath layer by two or four and form.
Cost is higher but screen adopts the tinned wird braided material, and restrictive coating adopts polythene material can cause cable harder, and bending property is not good, the poor-performing of acid and alkali-resistance etc.
Summary of the invention
The purpose of this invention is to provide a kind of railway transponder stube cable, can reduce the cost of screen under the prerequisite that guarantees the cable shield performance, improve simultaneously mechanical and physical performance, environmental resistance and the chemical resistance of cable.
Technical solution of the present invention is:
A kind of railway transponder stube cable is provided, consists of insulated wire cores by insulating barrier parcel conductor, two or four are thoroughly done away with the stranded rear wrapped one deck belting layer of edge core, and belting layer is enclosed with screen, restrictive coating outward successively.
As the further improved railway transponder stube cable of the present invention, described conductor is five class twisted copper conductors, and sectional area is 0.7 square millimeter～0.8 square millimeter.
As the further improved railway transponder stube cable of the present invention, described insulating barrier is that polythene material is made, and thickness is 0.5 millimeter～0.7 millimeter.
As the further improved railway transponder stube cable of the present invention, described screen is that the aluminum-magnesium alloy wire braided material is made.
As the further improved railway transponder stube cable of the present invention, the diameter of described aluminum-magnesium alloy wire is 0.1 millimeter, 0.15 millimeter or 0.2 millimeter, and its count is 60%～90%.
As the further improved railway transponder stube cable of the present invention, described restrictive coating is that the thermoplastic elastomer material is made.
Railway transponder stube cable provided by the present invention replaces tinned wird with the material of metal knitted screen with aluminum-magnesium alloy wire, has been reduced to cost; Restrictive coating is replaced common polythene material with the thermoplastic elastomer material of function admirable, made cable cover(ing) more soft, improved simultaneously the mechanical strength of cable, the mechanical and physical performance of resistance to wear, also improved the performance of the anti-environment of cable, chemically-resistant article.
Description of drawings
Fig. 1, the structural representation of railway transponder stube cable provided by the present invention.
1 is restrictive coating, and 2 is screen, and 3 is belting layer, and 4 is conductor, and 5 is insulating barrier.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples, the present invention is described in further detail, this embodiment only is used for explaining the present invention, does not consist of the restriction to protection range of the present invention.
Railway transponder stube cable as shown in Figure 1 consists of insulated wire cores by insulating barrier 5 parcel conductors 4, and described conductor 4 is five class twisted copper conductors, and sectional area is 0.7 square millimeter～0.8 square millimeter; Described insulating barrier 5 is made for polythene material, and thickness is 0.5 millimeter～0.7 millimeter.Two or four are thoroughly done away with the stranded rear wrapped one deck belting layer 3 of edge core, outer screen 2, the restrictive coating 1 of being enclosed with successively of belting layer 3.
Described screen 2 is made for the aluminum-magnesium alloy wire braided material.Aluminum-magnesium alloy wire has that density is low, mechanical strength is high, radiation conductive better, the advantage such as crushing resistance is stronger, can fully satisfy the requirement of electromagnetic shielding, and the more conventional tinned wird of use amount can reduce greatly, therefore can reduce costs.
The diameter of described aluminum-magnesium alloy wire is 0.1 millimeter, 0.15 millimeter or 0.2 millimeter, and its count is 60%～90%.
Described restrictive coating 1 is made for the thermoplastic elastomer material.Thermoplastic elastomer plasticity is strong, be easy to shape, and good springiness, intensity is high, rebound performance is good, and environment-protecting asepsis, the quality softness is easy to bending, and is weather-proof, heat resistance is strong.
