Abstract
The invention relates to a railway signal cable with an aluminum sheath, which comprises a cable core, an aluminum sheath, a hot melt adhesive layer, an inner cushion layer, an armoured layer and a sheath layer, wherein the cable core is formed by stranding a plurality of single wires; the aluminum sheath is longitudinally wrapped around the periphery of the cable core and is produced through argon arc welding; the hot melt adhesive layer is extruded outside the aluminum sheath; the inner cushion layer is extruded on the periphery of the hot melt adhesive layer; the armoured layer is wrapped on the periphery of the inner cushion layer; and the sheath layer is extruded on the periphery of the armoured layer. The railway signal cable has the advantages that the railway signal cable with an aluminum sheath can provide strong protection for the aluminum sheath which functions as a shielding layer, while increasing the peel strength between the aluminum sheath and the inner cushion layer and also strengthening the anticorrosion ability of the cable with an aluminum sheath. The investment is small and the profit is high.
Description
Technical field
The present invention relates to a kind of aluminum-sheathed cable, especially relate to a kind of aluminium sheath railway signal cable that is applied on the railway.
Background technology
Along with the fast development of Chinese Railway market, railway has been the first-selected trip instruments of compatriots, as the demand of supporting with it railway signal cable also in further increase.Existing railway signal cable is usually by cable core and be coated on cable core outer aluminium sheath, inner cushion layer, metal armouring layer, polyethylene oversheath from the inside to the outside successively and form.
Summary of the invention
Technical problem to be solved by this invention is a kind of hot melt adhesive layer to be provided, the aluminium sheath railway signal cable of the peel strength between enhancing aluminium sheath and the inner cushion layer.
In order to solve the problems of the technologies described above; The present invention realizes through following technical scheme: this aluminium sheath railway signal cable comprises the cable core that is twisted into by a plurality of single lines, the vertical aluminium sheath that is wrapped in cable core peripheral applications argon arc welding explained hereafter, extrudes hot melt adhesive layer outside aluminium sheath, extrudes inner cushion layer in the hot melt adhesive layer periphery, wrapped armour and extrusion molding in the inner cushion layer periphery be at the restrictive coating of armour periphery.
Preferably, the thickness that extrudes of described hot melt adhesive layer is 0.02-0.03 mm.
Preferably, described single line is made up of copper conductor and the insulating barrier that is coated on the copper conductor periphery.
Preferably, described armour comprises that two-layer gap successively is wrapped in the galvanized steel strip of inner cushion layer periphery.
Preferably, said inner cushion layer extrudes thickness at 0.7mm-1.0mm.
Compared with prior art; Usefulness of the present invention is: this aluminium sheath railway signal cable has stronger protective effect to the aluminium sheath that plays the screen effect; Increased the peel strength between aluminium sheath and the inner cushion layer simultaneously; Also strengthened the antiseptic power of aluminum-sheathed cable, dropped into for a short time, income is big.
Description of drawings:
Below in conjunction with accompanying drawing the present invention is further specified.
Accompanying drawing 1 is the structural representation of aluminium sheath railway signal cable of the present invention.
In the above accompanying drawing: 1, cable core; 11, single line; 12, copper conductor; 13, insulating barrier; 2, aluminium sheath; 3, hot melt adhesive layer; 4, inner cushion layer; 5, armour; 6, restrictive coating.
Embodiment:
Describe the present invention below in conjunction with accompanying drawing and embodiment:
A kind of aluminium sheath railway signal cable shown in Figure 1; Comprise the cable core 1 that is twisted into by a plurality of single lines 11, the vertical aluminium sheath 2 that is wrapped in cable core 1 peripheral applications argon arc welding explained hereafter, extrude hot melt adhesive layer 3 outside aluminium sheath 2, extrude inner cushion layer 4 in hot melt adhesive layer 3 peripheries, wrapped armour 5 and extrusion molding in inner cushion layer 4 peripheries be at the restrictive coating 6 of armour 5 peripheries; Hot melt adhesive layer 3 production technologies are simple; Extrude together with inner cushion layer; One-shot forming, aluminium sheath 2 is welded in cable core 1 periphery through the vertical bag of argon arc welding.Described PUR; 3 the thickness that extrudes is 0.02-0.03 mm; Described single line 11 is made up of copper conductor 12 and the insulating barrier 13 that is coated on copper conductor 12 peripheries, and described armour 5 comprises that two-layer gap successively is wrapped in the galvanized steel strip of inner cushion layer 4 peripheries, and said restrictive coating 6 is the pe sheath layer; Said inner cushion layer 4 extrude thickness at 0.7mm-1.0mm, extrude by polythene material and form.
This aluminium sheath railway signal cable has stronger protective effect to the aluminium sheath that plays the screen effect, has increased the peel strength between aluminium sheath and the inner cushion layer simultaneously, has also strengthened the antiseptic power of aluminum-sheathed cable, drops into for a short time, and income is big.
It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
