Description
Technical field
The utility model relates to electricity field, particularly relates to that a kind of vertical wirings is resistance to draws cable.
Background technology
At present, needing the environment carrying out cable vertical wirings, as the dispensing electricity etc. under skyscraper delivery electricity, mine, the general power cable used is steel-tape armouring or wire armoring type power cable, has good pull resistance.But in the distribution system that these vertical-rise cables connect up, because the vertically disposed length of cable is general longer, the quality of cable self adds steel-tape armouring or steel wire armoured quality will be very large, can be very high to the stiff end requirement of strength of cable, the stiff end arranged is also more, cause installation cost to increase, and be unfavorable for the installation of cable.
Utility model content
The purpose of this utility model is to provide that a kind of vertical wirings is resistance to draws cable, improves its pull resistance, reduce stiff end requirement of strength of the present utility model by multiple injection molded layers structure.
In order to achieve the above object, the utility model provides following technical scheme:
A kind of vertical wirings is resistance to draws cable, and cable core comprises conductor, fiber-filled layer and core insulation injection molded layers from the inside to surface successively, and the outside of cable core sets gradually injection moulding sheath, wrapped cable-type padlock sheath, injection moulding sheath and lock armour oversheath.Core insulation injection molded layers is set in cable core, and at the two-layer injection moulding sheath of its outer setting, forms the injection molded layers of three layers, improve tensile property of the present utility model.
Further, also comprise glass fibre, glass fibre is arranged on inside or the surface of core insulation injection molded layers and/or injection moulding sheath.Increased the tensile property of injection molded layers by glass fibre, further increase tensile property of the present utility model.
Further, also comprise code identification portion, code identification portion is arranged on the outside of lock armour oversheath.Code identification portion makes the utility model possess identification, uses the situation of multi-cable at the scene simultaneously, easily identifies it.
Further, the periphery in code identification portion arranges boss.The mid portion height in code identification portion lower than the height of boss, thus ensures that the mark word of mid portion or identifier are not easy to rub with outside.
Further, also comprise reflector, reflector is arranged on lock armour oversheath.Reflector adopts material light to larger reflectivity.The direct reflection ray in reflector, can point out position of the present utility model, conveniently overhaul, and when outside ambient light is darker, during as shaft bottom, can not touch situation of the present utility model.
Further, core insulation injection molded layers and injection moulding sheath are polyvinyl chloride injection moulding.
Further, locking armour oversheath is aluminium alloy lock armour oversheath.
Further, cable core is the one in single core, twin-core, three cores, four-core and five cores.
Further, conductor is copper conductor.
The beneficial effects of the utility model are:
1) injection molded layers of three layers and glass fibre structure is adopted to improve tensile property of the present utility model;
2) code identification portion makes the utility model possess identification, uses the situation of multi-cable at the scene simultaneously, easily identifies it;
3) the direct reflection ray in reflector, can point out position of the present utility model.

Embodiment
Below in conjunction with accompanying drawing of the present utility model, be clearly and completely described the technical solution of the utility model, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Shown in Fig. 1-2, a kind of vertical wirings is resistance to draws cable, and cable core comprises copper conductor 1-1, fiber-filled layer 1-2 and core insulation PVC injection molded layers 1-3 from the inside to surface successively, and cable core is single cored structure.The outside of cable core sets gradually polyvinyl chloride injection moulding sheath 1-4, wrapped cable-type padlock sheath 1-5, polyvinyl chloride injection moulding sheath 1-6 and aluminium alloy lock armour oversheath 1-7.The inside of polyvinyl chloride injection moulding sheath 1-6 arranges glass fibre 1-9.
At the outer setting reflector 1-8 of aluminium alloy lock armour oversheath 1-7.Reflector 1-8 adopts material light to larger reflectivity.The outside of aluminium alloy lock armour oversheath 1-7 also arranges code identification portion 1-11.The periphery of code identification portion 1-11 arranges boss 1-12.The mid portion 1-10 of code identification portion 1-11 is highly lower than the height of boss 1-12.The mid portion 1-10 of code identification portion 1-11 is used for Printing Marks or word.
The above; be only embodiment of the present utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection range of the present utility model.Therefore, protection range of the present utility model should described be as the criterion with the protection range of claim.
