Abstract
The utility model discloses a light -duty control cable of high drop, including insulation core, many insulation core strand into the cable core, the outside of cable core by interior outside to in proper order the parcel have band, shielding layer and sheath, insulation core includes by the interior aramid fiber yarn that sets gradually outside to, a plurality of gangs of copper clad aluminum alloy conductor and insulating layer. The adoption of aramid fiber yarn material, copper clad aluminum alloy conductor replace traditional copper conductor and insulating layer and sheath all to adopt the elastomer materials that proportion is lighter, have alleviateed the weight of cable itself on the one hand, have greatly improved holding of cable simultaneously and have drawn intensity, satisfy the required control cable's in high drop area needs completely.
Description
Technical field
The utility model belongs to field of cable technology, is specifically related to a kind of high drop light control cable.
Background technology
Due to the needs of the particularly high drop area operation on high mountain hills, high drop lightweight control cables as the product supporting with it, range of application and usage quantity more and more wider.High drop lightweight control cables be mainly used in field particularly high mountain hills and high drop area operation needs.Because drop is comparatively large, just need the cable used can bear and lighter in weight own.
Due to increasing of field work, complicated geographical environment, particularly high drop area, particular/special requirement be it is also proposed to control cables supporting with it: cold-resistant, the wear-resisting and function of shielding that usual field control cables not only will be had to possess, and require to be applicable to bearing and lightweight feature itself of high drop area.Because general control cables does not possess These characteristics, this just requires producer's Gonna breakthrough technology barriers, seeking breakthrough in the construction of cable and cable new material and new technology.
Summary of the invention
According to above the deficiencies in the prior art, technical problem to be solved in the utility model proposes a kind of high drop light control cable, with reach have excellent to bear, the object of light-weight characteristics own.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of high drop light control cable, comprise insulated wire cores, many insulated wire cores are twisted into cable core, the outside of described cable core is enclosed with band, screen and sheath from inside to outside successively, and described insulated wire cores comprises the aramid yarn set gradually from inside to outside, some strands of copper-clad aluminum alloy conductors and insulating barrier.
Preferably, described aramid yarn is that bundle tangles structure, some strands of copper-clad aluminum alloy conductors centered by the aramid yarn restrainting strand multiple strand outside it.
Preferably, the material of described insulating barrier is TPE elastomer material.
Preferably, described band is polyester belt.
The material of described sheath is polyurethane elastomer material.
Preferably, described screen is the screen being woven with copper-clad aluminum alloy silk and being added with aramid yarn, and count is not less than 80%.
The utility model beneficial effect is:
1, the utility model conductor adopts the aramid yarn of bundle strand and twists multiply copper-clad aluminum alloy conductor again around it, because the tensile strength of aramid yarn is even higher than steel wire, so what substantially increase cable bears intensity;
2, the utility model due to the conductor twisted again around center aramid yarn be copper-clad aluminum alloy material, this material, under the prerequisite not affecting Signal transmissions, significantly reduces the weight of conductor, also mitigates the weight of cable thus;
3, the utility model all adopts elastomeric material due to insulating barrier and sheath, also which reduces the weight of cable;
4, the utility model adopts copper-clad aluminum alloy silk and is added with the woven shield of aramid yarn, serves good shielding action and supplement to strengthen drawing-resistant function.
The employing of aramid yarn material, copper-clad aluminum alloy conductor replace traditional copper conductor and insulating barrier and sheath all to adopt the elastomeric material that proportion is lighter, alleviate the weight of cable itself on the one hand, what greatly improve cable bears intensity simultaneously, meets the needs of control cables needed for high drop area completely.
Accompanying drawing explanation
Below the content expressed by this Figure of description and the mark in figure are briefly described:
Fig. 1 is the structural representation of embodiment of the present utility model.
In figure 1, aramid yarn, 2, copper-clad aluminum alloy conductor, 3, insulating barrier, 4, band, 5, screen, 6, sheath.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is as the effect of the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part and operation principle, manufacturing process and operation using method etc., be described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present utility model, technical scheme.
As shown in Figure 1, a kind of high drop light control cable, insulated wire cores is formed by aramid yarn 1, copper-clad aluminum alloy conductor 2 and the elastic body insulated layer 3 extruded thereon, cable core is twisted into by many described insulated wire cores, at the outer overlapping wrapped band 4 of described cable core, band preferably adopts polyester belt, and outside described band, be woven with copper-clad aluminum alloy silk and be added with the screen 5 of aramid yarn, the outermost layer of cable extrudes elastic body jacket 6.
Preferably, corresponding vibrational power flow and Material selec-tion are respectively:
Aramid yarn 1 is twisted by multiply aramid yarn bundle to form, and when requiring each stock aramid yarn without disconnected stock and restraint strand, tension is even;
Copper-clad aluminum alloy conductor 2 adopts the mode of first bundle strand multiple strand more stranded around the aramid yarn at center, requires that the layers of copper of copper cover aluminum should be coated on aluminium alloy core evenly, continuously, and its surface should smooth, rounding, the defects such as the pit that do not have, crack, dew aluminium;
Insulating barrier 3 adopts TPE elastomer material to extrude to form;
Lapping layer 4 adopts polyester belt 2 ply wrapped outside cable core;
Copper-clad aluminum alloy silk and be added with aramid yarn strengthen screen 5, count is not less than 80%;
Oversheath 6 adopts and extrudes polyurethane elastomer protective cover material.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection range of the present utility model without to improve.The protection range that protection range of the present utility model should limit with claims is as the criterion.
