Abstract
The utility model relates to a cross link electric cable with a splined external coating, which can be a single core structure and also be a three-core structure. The outlines of restrictive coatings (8, 8') of the single core structure and the three-core structure form a concave and convex gear shape. The utility model changes the round plane structure of the restrictive coating of the existing cross link electric cable into the structure that the outline of the restrictive coating of the cross link electric cable forms the concave and convex gear shape, so the friction force in work process is reduced. Because the outline of the outer coating forms the concave and convex gear shape, the surface contact of the round cable outer coating is changed into the point contact thereof, so the scratching phenomenon of the outer coating in the work process of cable installation is reduced, and installation and operation are convenient. Meanwhile, the surface area of the cable outer coating can be increased so that heat generated in the operational process of the cable can be completely diffused, and the service life of the cable is prolonged. The utility model provides a novel product for the field of electrical wire and cable manufacture.
Description
Technical field: the utility model relates to mechanical manufacturing field, exactly belongs to electric wire and makes the field.
Technical background: the crosslinked cable technical development is very fast, has become the principal item on electric power transmission ﹠ distribution line sending road at present.Because characteristics such as the crosslinked cable general requirements is big, Heavy Weights, friction is big in laid processes, and difficulty of construction is big, and occurs oversheath scuffing phenomenon easily, brings a lot of inconvenience for user and cable manufacturer.
The utility model content: the utility model can be single cored structure, also can be three-core structure, and single cored structure is made up of conductor, conductor shield, insulating barrier, insulation screen, resilient coating, metal sheath layer, anticorrosive coat, restrictive coating and semi-conductive layer; Three-core structure is to thoroughly do away with by three that skin is lapping layer, inner cushion layer, armour and restrictive coating successively behind edge shielding cores and the stranded stranding of packing material.The utility model is that the outline that former crosslinked cable restrictive coating circular flat structure makes the crosslinked cable restrictive coating into is the shaggy tooth wheel-like structure, reduce friction in the cable laying operation process, because the oversheath outline is the shaggy tooth colyliform, face contact by the round cable oversheath changes a contact into, reduce the scuffing phenomenon of oversheath in the cable installation process, easy to install; Simultaneously, the cable jacket surface area enlarges markedly, and the heat that produces in the cable running is distributed fully, improves cable useful life.
Description of drawings: the utility model specification comprises a width of cloth accompanying drawing, and the drawing of this accompanying drawing is described as follows:
Fig. 1, the utility model list cored structure schematic cross-section
Fig. 2, the utility model three-core structure schematic cross-section
Among the figure: 1 is conductor, and 2 is conductor shield, and 3 is insulating barrier, and 4 is insulation screen, and 5 is resilient coating, 6 is metallic sheath, and 7 is anticorrosive coat, and 8,8 ' is restrictive coating, and 9 is semi-conductive layer, 10 insulation shielding cores, 11 is packing material, and 12 is lapping layer, and 13 is inner cushion layer, and 14 is armour.
The utility model execution mode: the utility model can be single cored structure, it also can be three-core structure, single cored structure is made up of conductor 1, conductor shield 2, insulating barrier 3, insulation screen 4, resilient coating 5, metal sheath layer 6, anticorrosive coat 7, restrictive coating 8 and semi-conductive layer 9, three-core structure thoroughly does away with edge shielding cores 10, packing material 11, lapping layer 12, inner cushion layer 13, armour 14 by three to be formed with restrictive coating 8 ', and restrictive coating 8,8 ' outline are the shaggy tooth colyliform; Wherein, restrictive coating (8,8 ') is to be extruded by vinyon to form, and also can be extruded by igelite to form.Inner cushion layer 13 of the prior art can have also as required and can not have, and armour 14 can be a steel-tape armouring, also can be wire armoring, aluminium wire armouring.
