Abstract
The utility model discloses a railway-responder connection shield cable. An insulating layer wraps a conductor to form an insulating wire core. Two or four insulating wire cores are intertwisted and then wrapped by a belting layer which is sequentially wrapped by a shielding layer and a sheath layer. The shielding layer is a braided shielding layer which is formed by semiconductive band wrapping, semiconductive materials extruding, and adding metal fiber for mixing. The railway-responder connection shield cable provided by the utility model can improve the shielding performance of a cable, and improve the mechanical and physical performances, the performance of environment resistance, and the performance of chemical resistance at the same time.
Description
Technical field
The utility model relates to technical field of electric wires and cables, relates in particular to a kind of railway transponder and connects shielded type cable.
Background technology
Railway transponder connects shielded type cable and is mainly used in two ends, station, is arranged on open air, and environment for use is more severe.Railway transponder of the prior art connects shielded type cable and exists shielding properties, mechanical and physical performance, environmental resistance and chemical resistance to need the demand further improving.
Summary of the invention
The purpose of this utility model is to provide a kind of railway transponder and connects shielded type cable, can improve the shielding properties of cable, improves mechanical and physical performance, environmental resistance and the chemical resistance of cable simultaneously.
Technical solution of the present utility model is:
Provide a kind of railway transponder to connect shielded type cable, by insulating barrier parcel conductor, form insulated wire cores, two or four stranded rear wrapped one deck belting layers of insulated wire cores, belting layer is enclosed with screen, restrictive coating outward successively, and described screen is that the wrapped semiconductive material that adds of semi-conductive tape extrudes and adds metallic fiber mixed weaving screen again.
As the further improved railway transponder of the utility model, connect shielded type cable, it is characterized in that: described insulating barrier is ethylene-propylene rubber material.
As the further improved railway transponder of the utility model, connect shielded type cable, it is characterized in that: described restrictive coating is that thermoplastic elastomer material is made.
Railway transponder provided by the utility model connects shielded type cable, can improve the shielding properties of cable, improves mechanical and physical performance, environmental resistance and the chemical resistance of cable simultaneously.
Accompanying drawing explanation
Fig. 1, railway transponder connects the structural representation of shielded type cable.
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, to understanding of the present utility model, below in conjunction with drawings and Examples, the utility model to be described in further detail, this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection range.
Railway transponder as shown in Figure 1 connects shielded type cable, by insulating barrier 5 parcel conductors 4, form insulated wire cores, two or four stranded rear wrapped one deck belting layers 3 of insulated wire cores, outer screen 2, the restrictive coating 1 of being enclosed with successively of belting layer 3, described screen 2 adds semiconductive material and extrudes and add metallic fiber mixed weaving screen again for semi-conductive tape is wrapped.Particularly, described insulating barrier 5 is ethylene-propylene rubber material.Particularly, described restrictive coating 1 is made for thermoplastic elastomer material.
