Abstract
The invention discloses a wear resisting and drag resisting power cable, and relates to the technical field of cables. The wear resisting and drag resisting power cable comprises conductor cores, wherein an aramid fiber reinforcement rope core is arranged in each strand of copper wires in each conductor core, a wire core is formed by wrapping each conductor core with a polyurethane insulating layer, three wire cores are wrapped with polyester wrapping tapes so as to form a cable core, the cable core is filled with the aramid fiber reinforcement rope cores, polyurethane inner sheath layers are arranged on the exteriors of the polyester wrapping tapes, aramid fiber braid layers wrap the polyurethane inner sheath layers, and polyurethane outer sheath layers are arranged on the exteriors of the aramid fiber braid layers. The wear resisting and drag resisting power cable is reasonable in design, guarantees overall soft performance due to the fact that a conductor is of a sixth soft copper wire stranding structure, guarantees overall drag resisting performance due to the fact that all components are of reinforced structure, and has excellent pull resisting, wear resisting and tear resisting performance due to the fact that an outer sheath is made of polyurethane material. Accordingly, the wear resisting and drag resisting power cable has the advantages of being good in bending performance, drag resistance, good in wear resistance and the like.
Description
Technical field
The present invention relates to cable, particularly relate to a kind of wear-resisting anti-dilatory power cable.
Background technology
Wear-resistant tensile power cable conventional at present mainly adopts rubber insulation and sheath class cable, rubber insulation and jacket-class product need rubber dedicated extruder to extrude, also need steam pressure sulfuration in addition, production line output investment ratio is higher, Product Process more complicated, speed of production is slow, and production waste is larger, and cost compare is high.The impart tear of rubber class sheath material is poor in addition, and therefore when cable pull and friction, easily occur cracking, life of product is shorter, needs frequently to change cable.
Summary of the invention
For solving above-mentioned technological deficiency, the object of the invention is to provide a kind of wear-resisting anti-dilatory power cable.
The solution of the present invention is as follows: a kind of wear-resisting anti-dilatory power cable, and include conductor cores, be provided with aramid fiber in conductor cores in each stock copper wire and strengthen wire rope core, conductor cores is outward by the wrapped one-tenth core of polyurethane insulating layer, and three cores become cable core by polyester band band; Fill aramid fiber in cable core and strengthen wire rope core; Arrange polyurethane inner restrictive coating outside polyester band, inner restrictive coating outsourcing aramid fiber braid, arranges polyurethane external sheath layer outside aramid fiber braid.
Accompany an aramid fiber in the middle of described three cores and strengthen wire rope core.
Described aramid fiber braid is aramid fiber yarn braiding, and count is not less than 60%.
The present invention is reasonable in design, conductor is the softness that 6 class soft copper silk lay configuration ensure that whole cable, and each parts adopt strengthens structure, ensure that the anti-dilatory performance of whole cable, oversheath adopts polyurethane material material, has excellent tension, wear-resisting, tear resistance.Thus, the present invention has good bending property, resists the advantages such as dilatory, anti-wear performance is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Wherein: 1, conductor cores; 2, aramid fiber strengthens wire rope core; 3, polyurethane insulating layer; 4, polyester band; 5, inner restrictive coating; 6, aramid fiber braid; 7, polyurethane external sheath layer.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described;
As shown in Figure 1, a kind of wear-resisting anti-dilatory power cable, include conductor cores 1, be provided with aramid fiber and strengthen wire rope core 2 in conductor cores 1 in each stock copper wire, conductor cores 1 is outer by the wrapped one-tenth core of polyurethane insulating layer 3, and three cores become cable core by polyester band 4 band; Fill aramid fiber in cable core and strengthen wire rope core 2, as tensile elements; Arrange polyurethane inner restrictive coating 5 outside polyester band 4, inner restrictive coating 5 outsourcing aramid fiber braid 6, arranges polyurethane external sheath layer 7 outside aramid fiber braid 6.
Accompany an aramid fiber in the middle of described three cores and strengthen wire rope core 2.
Described aramid fiber braid 6 is aramid fiber yarn braiding, and count is not less than 60%.
Conductor in described conductor cores 1 is 6 class soft copper silk lay configuration, mixes a part of aramid fiber reinforced wire in proportion as strengthening core during conductor synnema, and ensure that cable is when dilatory, copper conductor plastic deformation can not occur.
Although give detailed description and explanation to the specific embodiment of the present invention above; but what should indicate is; we can carry out various equivalence according to conception of the present invention to above-mentioned execution mode and change and amendment; its function produced do not exceed that specification contains yet spiritual time, all should within protection scope of the present invention.
