Abstract
A waterproof railway digital signal cable belongs to cable technical field. The cable comprises an electrical conductor, an insulating barrier on the electrical conductor, a CV binding and an outer sheath on the cable core and is characterized in that the utility model is provided with an aluminum plastic tape, and a super conducting magnetic steel belt shielding layers and three water-blocking tapes; petroleum butter is filled in the gap of the cable core and the super conducting magnetic steel belt and among all layers. The utility model adopts aluminum plastic tape corrugated longitudinal cladding and super conducting magnetic steel belt armoring for double layer of shielding, with good shielding effect. Three layers of water-blocking tapes and the petroleum butter filled in the gap of the cable core and the super conducting magnetic steel belt can improve the longitudinal and transverse waterproof performance of the cable and the cable anticorrosion grade and transmission performance. The covering insulating barrier can prevent the petroleum from immerging into air holes and gaps and guarantee the cable insulation performance, with good value for spreading and market prospect.
Description
Technical field
The utility model relates to a kind of digital signal cable, and particularly the structure of water proof type railway digital signal cable belongs to the cable technology field.
Background technology
Existing railway digital signal cable is made of conductor, insulating layer of conductor, composite sheath, aluminium sheath, oversheath etc., is the aluminium sheath shield type.This cable size is big, and weight is big, and it is big that bending radius is installed, need be in aluminium sheath maintenance by gas pressuriztion, defective easily takes place in aluminium sheath in the welding manufacture process, need repair welding, and the general repair welding time surpasses the production time, and the easy burn-out cable core, cause broken end, influence the quality of product.
Summary of the invention
The purpose of this utility model be to provide that a kind of diameter is little, light weight, the manufacturing be convenient, cost is low, the water proof type railway digital signal cable that serviceability is good.
The purpose of this utility model is to realize by the improvement to existing railway digital signal cable, the water proof type railway digital signal cable, comprise conductor, insulating barrier on the conductor and the CV band on the cable core, composite sheath, oversheath, it is characterized in that the water proof type railway digital signal cable is provided with aluminium-plastic tape (6), (9) two layers of screen of superconduction magnet steel band and three layers of waterstop (5), (8), (10), internal layer waterstop (5) is wrapped on CV band (4), CV band (4) is gone up alclad plastic composite strip (6), composite sheath (7), go up wrapped middle level waterstop (8) at composite sheath (7), superconduction magnet steel band (9) is set on waterstop (8), outer waterstop (10) is arranged between superconduction magnet steel band and the oversheath (11), in cable core, the superconduction magnet steel band gap filled stone ointment (3) between each covering that neutralizes.Said aluminium-plastic tape (6) wrinkle is vertical to be wrapped on the CV band (4).Superconduction magnet steel band (9) armouring is on middle level waterstop (8).Insulating barrier is skin-foam-skin insulation layer (2).
The utility model is rational in infrastructure simple, manufactures easily, and cost is low, good product quality, and working service is convenient.Adopt vertical bag of aluminium-plastic tape wrinkle and superconduction magnet steel band armouring double layer screen, shield effectiveness is good.Wrapped three layers of waterstop and in cable core, in the superconduction magnet steel band gap, between each covering the filled stone ointment, both improved vertical water resistance of cable, improve the water resistance of walking crosswise of cable again, improve the corrosion protection grade and the transmission performance of cable simultaneously.Suitcase skin insulating barrier avoids petroleum jelly to immerse pore, gap, guarantees insulating performance of cable.
Description of drawings
Accompanying drawing is a structural representation of the present utility model, 1 conductor, 2 suitcase skin insulating barriers, 3 petroleum jellys, 4CV band, 5 internal layer waterstops, 6 aluminium-plastic tapes, 7 composite sheaths, 8 middle level waterstops, 9 superconduction magnet steel bands, 10 outer waterstops, 11 oversheaths among the figure.
Embodiment
The many copper conductors that have a suitcase skin insulating barrier 1 plying is cable core, filled stone ointment 3 in cable core, with CV band 4 that cable core is wrapped earlier, wrapped internal layer waterstop 5 on CV band 4 adopts aluminium-plastic tape 6 the vertical bag of wrinkles again on the internal layer waterstop.Composite sheath 7 is set, wrapped middle level waterstop 8 on the composite sheath, the periphery armoured superconductive magnet steel band 9 of middle level waterstop, the superconduction magnet steel band gap filled stone ointment between each covering that neutralizes on aluminium-plastic tape.Outer waterstop 10 is wrapped on superconduction magnet steel band, and the outermost layer of cable is provided with oversheath 11.
