Abstract
The invention discloses a high-speed railway network data cable comprising a main conductor and control conductors. The main conductor and the control conductors are respectively subjected to extrusion molding to form in a double-layer expanded-plastic insulating layer, and are sequentially coated with a non-hygroscopic internal isolation layer, an aluminum-plastic composite belt interlocking armor layer, a tinned-copper-wire braid shielding layer, a non-hygroscopic external isolation layer, a glass fiber braid layer, a water stopping yarn filling layer and a low-smoke-zero-halogen thin-wall outer sheath after being bunched. A low-smoke-zero-halogen inflame-retardant material filing core is arranged on the inner side of the non-hygroscopic internal isolation layer. The high-speed railway network data cable has the advantages that standard stranded structures are combined with bunched or stranded structures, composite shielding formed by aluminum-tape lapping is added to the shielding layer, shielding effect of the cable is improved, the tinned-copper-wire braid shielding layer is optimized, braiding density is larger than 90%, the cable has excellent electromagnetic interference resistance performance, low smoke, zero halogen and flame retardance are realized, and physical and mechanical property is excellent.
Description
Technical field
The present invention relates to cable technology field, relate in particular to a kind of high-speed railway network data cable.
Background technology
The cable that is applicable to EMU project and is widely used in subway, city rail vehicle market need to have fire-resistant, low cigarette, halogen-free flameproof, waterproof, the antitorque characteristic of tension, existing this type of cable can't well meet user demand, and complex structure, weight is large, cost is high, need to improve.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, and a kind of high-speed railway network data cable is provided.
The present invention is achieved by the following technical solutions:
A kind of high-speed railway network data cable, include leading body and control conductor, described leading body and control conductor difference extrusion moulding are in double-layer foamed plastic insulating layer, leading body and two are controlled after conductor bundle strand in outside is coated with non-water absorption successively to separator, fiberglass braided layer, water blocking yarn packed layer and low smoke and zero halogen thin-walled oversheath separator, aluminium-plastic tape lock armo layer, tinned copper wire woven shield, non-water absorption outside, in non-water absorption, inside separator, be also provided with halogen-free low-smoke flame retardant material filled core.
Advantage of the present invention is: structure bundle strand of the present invention or burst compound regular lay configuration of strand, twisted wire lay ratio be 8-10 doubly, double-layer foamed insulation, 3 single lines add one and fill the stranded cable core that forms a whole, twisting pitch is not more than 13 times of stranded external diameter, in screen, increase the composite shielding of the wrapped formation of aluminium strip, improve cable shield effect, optimize tinned copper wire woven shield, count is greater than 90%, has superior anti-electromagnetic interference performance, low cigarette, Halogen, fire-retardant, physical and mechanical properties is superior.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
