Abstract
A kind of cable for railway rolling stock, the conductor are provided with inner insulating layer outside, are provided with external insulation layer outside the inner insulating layer, the external insulation layer is provided with refractory layer, and the refractory layer outer layer is provided with cable cover(ing).The present invention uses double-layer insulating structure, once completes cable interior insulation, external insulation extrusion using double-layer coextrusion technique, when which can guarantee insulating exruded imperfect inside, external insulation can compensate at once, to ensure the performance of cable.Since TPEE and PEEK has good intermiscibility, the two is blended according to a certain percentage, and carrying out processing to surface makes the structure on its surface change, polarity and hydrophily are improved, to improve mechanics, calorifics and tribological property of active force and composite material etc., excellent modified elastomeric material can be obtained, meet ultrathin insulating layer processing technology.Polystyrene block copolymer SEBS material forms composite material through reasonable compatibility, becomes heat-resisting ageing-resisting, the composite material of good insulating.
Description
Technical field
The invention belongs to field of cable technology, and in particular to a kind of cable for railway rolling stock.
Background technique
Wire and cable is to transmit electric energy, information and the wire product for realizing electromagnetic energy conversion.The wire and cable of broad sense is also
The cable of referred to as cable, narrow sense refers to insulated cable, it may be defined as: the aggregate consisted of following parts；One or more
The clad that root insulated wire cores and each may have, total protective layer and outer jacket, cable can also have and additional not have
The conductor of insulation.As running velocity improves, there are requirements at the higher level, especially reliability requirement to the other performance of cable
It greatly improves.
Summary of the invention
In view of the deficienciess of the prior art, the present invention provides a kind of cable for railway rolling stock.
The present invention is achieved by the following technical solutions:
A kind of cable for railway rolling stock, including conductor, the conductor are provided with inner insulating layer, the inner insulating layer outside
It is provided with external insulation layer outside, the external insulation layer is provided with refractory layer, and the refractory layer outer layer is provided with cable cover(ing).
The conductor is constituted by tinned copper wire is twisted, and filament diameter should meet in GB/T4910 tinned copper wire standard about leading
The requirement of the external diameter margin of tolerance, i.e. 0.280+0.010-0.004mm, final conductor diameter≤2.43mm, conductor 20 after being twisted
DEG C D.C. resistance should be not more than 4.38 Ω/km, meanwhile, conductor roundness >=98%.
The inner insulating layer is not less than 10 using 20 DEG C of volume resistivities14The crosslinked polyolefin materials of Ω cm.
The external insulation layer is modified through polyester ether using polyether-ether-ketone, obtained modified elastomer material of good performance
Material.The refractory layer uses polystyrene block copolymer SEBS material.
Compared with prior art, the beneficial effects of the present invention are: the present invention uses double-layer insulating structure, using double-layer coextrusion
Technique once completes cable interior insulation, external insulation squeezes out, and when which can guarantee insulating exruded imperfect inside, external insulation can be stood
Quarter compensates, to ensure the performance of cable.Since TPEE (polyester ether) and PEEK (polyether-ether-ketone) has good intermiscibility,
The two is blended according to a certain percentage, and carrying out processing to surface makes the structure on its surface change, and polarity and hydrophily obtain
To improvement, to improve the mechanics of active force and composite material, calorifics and tribological property etc., excellent modified elastomer can be obtained
Material meets ultrathin insulating layer processing technology.Polystyrene block copolymer SEBS material forms composite material through reasonable compatibility,
As heat-resisting ageing-resisting, the composite material of good insulating.
Detailed description of the invention
Fig. 1 is structure chart of the invention.
In attached drawing: 1. conductors；2. inner insulating layer；3. external insulation layer；4. refractory layer；5. cable cover(ing).
Specific embodiment

Further, conductor 1 is constituted by tinned copper wire is twisted, and filament diameter should meet in GB/T4910 tinned copper wire standard
About the requirement of the conductor diameter margin of tolerance, i.e. 0.280+0.010-0.004mm, final conductor diameter≤2.43mm, after being twisted
20 DEG C of D.C. resistances of conductor should be not more than 4.38 Ω/km, meanwhile, conductor roundness >=98%.
Further, inner insulating layer 2 is not less than 10 using 20 DEG C of volume resistivities14The crosslinked polyolefin materials of Ω cm.
Further, external insulation layer 3 is modified through polyester ether using polyether-ether-ketone, obtained improved elastic of good performance
Body material.Refractory layer 4 uses polystyrene block copolymer SEBS material.
In conclusion only presently preferred embodiments of the present invention, is not used to limit the scope of implementation of the present invention, it is all according to
Equivalent changes and modifications carried out by shape described in scope of the invention as claimed, construction, feature and spirit should be included in this
In the scope of the claims of invention.
