Abstract
The utility model discloses a light special cable comprising a conductor, an insulating layer and an outer sheath layer. The conductor is formed by stranding and twisting a plurality of silver-plated copper wires, and a stranding pitch is within 20 times. The insulating layer and the outer sheath layer are arranged outside the conductor in order. The insulating layer is a thin wall layer made of polyolefin materials. According to the light special cable, since the silver-plated copper wires are employed by the conductor, a problem that the resistance of a joint is increased and the joint is heated caused by the oxidation of a copper conductor can be effectively prevented, and the reliability in a use process is increased. A stranded and twisted structure is employed by the conductor, the structure is symmetrical, and the stress of an electric wire in a bending process is uniform and stable. The insulating layer is the thin wall layer made of soft polyolefin materials with a high mechanical strength, so that the cable is favorable for environmental protection, and the materials have the advantages of allowance of high temperature, high resistance, small dielectric loss and the like.
Description
Technical field
The utility model relates to a kind of electric wire, specifically relates to a kind of light-duty special cable.
Background technology
At present, special equipment has the requirements such as volume is little, lightweight along with equipment performance improves constantly to special equipment.As extraordinary electric equipment, instrument and meter connecting line, require wire diameter little, adapt to that all kinds of adverse circumstances, ampacity are large and to bear overload capacity strong, and require cable to have good mechanical and physical performance.But existing normal cable can not satisfy this requirement.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of light-duty special cable, this cable possesses light weight, high temperature resistant, low temperature resistant, moisture-proof, weather-proof, ageing-resistant, thin insulating, thin sheath and the combination property such as soft, can adapt to multiple different operational environment.
To achieve these goals, the technical solution adopted in the utility model is: a kind of light-duty special cable, comprise conductor, insulating barrier and external sheath layer, described conductor is made of by bundle is stranded many silver-gilt copper wires, its twisted wire pitch is disposed with insulating barrier and external sheath layer outside conductor in 20 times; Described insulating barrier is the thin-walled layer take polyolefine material as material.
Preferably, described external sheath layer is extruded outside insulating barrier by polyurethane material.
Compared with prior art, the beneficial effects of the utility model are: conductor of the present utility model can prevent effectively that owing to adopting silver-gilt copper wire copper conductor from increasing the problems such as heating because oxidation makes itself and joint resistance, increases the reliability in use procedure; Conductor structurally adopts bundle strand lay configuration, and symmetrical configuration makes that electric wire is stressed in BENDING PROCESS evenly to be stablized; Its insulating barrier is that to adopt polyolefine material soft, high mechanical properties be the thin-walled layer of material, makes cable be conducive to environmental protection, and the material advantages such as to have the serviceability temperature of permission higher, and resistance is higher, and dielectric loss is less.This cable possesses light weight, high temperature resistant, low temperature resistant, moisture-proof, weather-proof, ageing-resistant, thin insulating, thin sheath and the combination property such as soft, can adapt to multiple different operational environment.
Description of drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1, conductor; 2, insulating barrier; 3, external sheath layer.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, light-duty special cable of the present utility model comprises conductor 1, insulating barrier 2 and external sheath layer 3, and described conductor 1 is made of by bundle is stranded many silver-gilt copper wires, and its twisted wire pitch is 10 times, is disposed with insulating barrier 2 and external sheath layer 3 outside conductor 1; Described insulating barrier 2 is the thin-walled layers take polyolefine material as material.Described external sheath layer 3 is extruded outside insulating barrier 2 by polyurethane material.
Above-mentioned is only a kind of embodiment of the present utility model; not in order to limit the utility model; those skilled in the art can make various changes and improve said structure; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
