Abstract
The utility model discloses a dragging cable used for a locomotive. The dragging cable used for the locomotive mainly comprises the copper cable cores, an insulating layer, a semiconductor insulating layer, a lapping layer, a galvanized copper strip armored layer and a sheath. The copper cable cores are extruded in the insulating layer, and each copper cable core is composed of a copper conductor and a semiconductor filling layer. The semiconductor insulating layer is wrapped on the outside of the insulating layer, and the lapping layer, the galvanized copper strip armored layer and the sheath are wrapped on the outside of the semiconductor insulating layer orderly. The cable of the utility model has a good tearing resistance, at the same time, has the characteristics of low smoke halogen free flame resistance, oil resistance, corrosion resistance, wear resistance, etc., and has the good toughness and bending resistance.
Description
Technical field
The utility model relates to field of cables, relates in particular to a kind of locomotive drag cable.
Background technology
At present, for dilatory locomotive or other cables for dilatory weight, to the pull resistance of cable and toughness and resistance to bend(ing) energy aspect, require all special high, if do not possessed, easily fracture, stiff, makes troubles and potential safety hazard to work, does not just possess the market competitiveness.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model be to provide a kind of anti-tear draw functional, and good toughness and resistance to bend(ing) can locomotive drag cable.
The utility model takes following technical scheme to realize: a kind of locomotive drag cable, it mainly comprises copper cable core, insulating barrier, semiconducting insulation layer, belting layer, zinc-plated copper strips armour and sheath.In described insulating barrier, be extruded with described copper cable core, described copper cable core is comprised of copper conductor and semiconductor packed layer, described insulating barrier is wrapped with described semiconducting insulation layer, and described semiconducting insulation layer is enclosed with belting layer, zinc-plated copper strips armour and sheath outward successively.
In described belting layer, zinc-plated copper strips armour and sheath, be all provided with a tension steel wire.
The utlity model has in sum following beneficial effect: this cable has the good anti-tear performance of drawing, also there is low-smoke non-halogen flame-retardant, oil resistant, characteristic and good toughness and the resistance to bend(ing) energy such as corrosion-resistant, wear-resisting simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional structure schematic diagram;
Wherein: 1, copper conductor; 2, semiconductor packed layer; 3, insulating barrier; 4, semiconducting insulation layer; 5, belting layer; 6, zinc-plated copper strips armour; 7, sheath; 8, tension steel wire.
Embodiment
As shown in Figure 1, a kind of locomotive drag cable, it mainly comprises copper cable core, insulating barrier 3, semiconducting insulation layer 4, belting layer 5, zinc-plated copper strips armour 6 and sheath 7.In described insulating barrier 3, be extruded with described copper cable core, described copper cable core is comprised of copper conductor 1 and semiconductor packed layer 2, described insulating barrier 3 is wrapped with described semiconducting insulation layer 4, outer belting layer 5, zinc-plated copper strips armour 6 and the sheath 7 of being enclosed with successively of described semiconducting insulation layer 4.
In embodiment: be all provided with a tension steel wire 8 in described belting layer 5, zinc-plated copper strips armour 6 and sheath 7.
The above is embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model application range therefore all changes or modifies, and is included in the utility model patent claim.
