Describe the invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
A kind of railway digital signal cable of Anti-freezing hardly possible accumulated snow, as shown in figure 1, include on the outside of cable core and cable core by it is interior extremely
The outer cable core belting layer 3 for coating successively, thermal insulation layer 4, protective metal shell 5, inner cushion layer 6, double-tape armor layer 7 and oversheath 8；It is described
Cable core includes at least one wire group 1, and the wire group is formed by two or four wires 2 are stranded.
Above-mentioned wire 2 includes conductor and the insulating barrier being arranged on outside conductor, and the insulating barrier is that skin-bubble-skin is three-layer co-extruded
Physical foam insulation, insulating resistance of cable is high, and signal transmission attenuation is small, and signal transmission distance is long, in the case where electric capacity is equal
Diameter is small, low cost.
Above-mentioned oversheath 8 includes cold resistance polyvinyl chloride sheath and the sheath set being coated on outside the cold resistance polyvinyl chloride sheath
Pipe.Hydrophobic coating is uniformly coated with cold resistance polyvinyl chloride jacket outer surface.The inwall of sheath sleeve pipe and outer surface all uniformly apply
It is covered with hydrophobic coating.When water droplet is when the coating surface is touched, can be slid because of the hydrophobic effect of coating, make jacket surface
Moisture is not retained, so as to reach the purpose of Anti-freezing.
Furthermore it is possible to some plastic slip rings are set sheath internal surface of sleeve pipe is equally spaced along its length, specifically, modeling
Material slip ring sleeve is mounted in cold resistance polyvinyl chloride sheath outside, it is possible to rotated along cold resistance polyvinyl chloride sheath.When ice and snow is stacked into one
When determining thickness, in the presence of the natural force such as deadweight or wind, the sheath sleeve pipe for being provided with plastic slip ring can be rotated, so that ice and snow
Naturally come off.
Cable manufacturing process is：First, 2 will produced according to demand or 4 wires of different colours 2 carry out stranded
Afterwards, polyester yarn is coated outside it, several wire groups 1 that will have been produced further according to demand be made by twisting cable core, and
Cable core outer cladding cable core belting layer 3；
One layer of thermal insulation layer 4 is extruded outside cable core belting layer 3 using extruding machine afterwards, thermal insulation layer can be PTFE layers；Then
Using argon arc welding continuous welding process in the outer cladding layer of metal sheath 5 of thermal insulation layer 4, and extruded in one layer outside protective metal shell 5
Lining 6；
Using steel band around-packing technology in the outer sinistral coiling gap of inner liner 6 around galvanized steel strip of double-baging as cable armouring
Layer, around the 45% of Inter-packet gap≤bandwidth, then extrudes one layer of cold resistance polyvinyl chloride sheath outside steel-tape armouring layer, and cold-resistant poly-
Vinyl chloride jacket surface coats one layer strong hydrophobic coating；
When sheath sleeve pipe with plastic slip ring is installed, cable core belting layer 3, thermal insulation layer 4, protective metal shell 5, interior will be coated with
Bed course 6, double-tape armor layer 7 and cable core one end of oversheath are connected with steel wire, and with pipe perforator by the steel wire with cable core one
And plastic slip ring is evenly arranged with through preprepared inwall, and inwall and surface are coated with the sheath of strong hydrophobic coating
In sleeve pipe.Strong hydrophobic coating is preferably also uniformly coated on the surface of plastic slip ring.
For convenience of construction, any that the sheath sleeve pipe being coated on outside cold resistance polyvinyl chloride sheath can be between slip ring and slip ring
Place carries out blocking construction, and such as cable need to bend and lay, then only sheath sleeve pipe need to be disconnected sheath sleeve pipe in knee, so that
Ensure that slip ring can rotate sheath sleeve pipe, it is ensured that accumulated snow is taken advantage of a situation and come off after accumulated snow by wind-force or Gravitative Loads.
The oversheath of this cable is evenly arranged with by the cold resistance polyvinyl chloride sheath and inwall that surface is coated with hydrophobic coating
The sheath sleeve pipe composition of plastic slip ring, when water droplet is when the coating surface is touched, can slide because of the hydrophobic effect of coating,
Jacket surface is set not retain moisture, so as to reach the purpose of Anti-freezing.Different from existing anti-freeze cable, this cable is not in electricity
Additionally heating element heater, the safer stabilization of cable work are set again, and save the consumption of additional energy source on cable, by hydrophobic material
Selection and plastic slip ring setting, it is ensured that cable has excellent Anti-freezing, anti-accumulated snow performance.In addition, in cable core outsourcing
Cable core band, thermal insulation layer, protective metal shell, inner cushion layer, double-tape armor layer are covered, makes cable that there is excellent heatproof, protection against the tide, screen
Cover, the function such as resistance to compression, anti-animal tooth are stung.
The preferred embodiment of the invention is the foregoing is only, creation is not intended to limit the invention, it is all at this
Within the spirit and principle of innovation and creation, any modification, equivalent substitution and improvements made etc. should be included in the invention
Protection domain within.
