Abstract
The utility model discloses an environment-friendly motor lead wire. The environment-friendly motor lead wire includes a conductor, an isolating layer, an insulating layer and an outer sheath layer, wherein the conductor is composed of silver-plated copper wires which are compositely twisted in a bundling and stranding manner, the isolating layer and the insulating layer are arranged successively outside the conductor so as to form an insulating wire core, the outer sheath layer is arranged outside the insulating wire core, and the insulating layer is made of a polyolefin material. According to the environment-friendly motor lead wire of the utility model, the silver-plated copper wires are adopted as the conductor, such that the problem such as heat emission caused by increased resistance at the conductor and a joint caused by the oxidation of the copper conductor can be effectively prevented; the conductor adopts a regularly bundle-twisted and strand-twisted composite structure, which enables a symmetrical structure, so that the wire can be uniformly and stably stressed in a bending process; the insulating layer is made of the soft and high-mechanical strength polyolefin material, so that the wire is conducive to environmental protection, and further, the material can be allowed to be used in high temperature, and is advantageous in 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 environment-friendly type motor lead.
Background technology
Motor lead is mainly used in the power transmission connecting line between electrical control gear and motor device, also can be applicable to the low-voltage direct transmission line.Existing motor lead, its structure that extrudes outside this class electric wire is also comparatively simple, comprises soft copper conductor and insulating barrier.Insulating layer material is different according to conductor long-term work temperature traditionally, adopts PVC, ethylene-propylene rubber, silicon rubber etc.Along with the reinforcement of environmental consciousness, the insulating layer material of such cable can not satisfy the requirement of " ROHS ".For the future developing trend of such electric wire, not only to have higher temperature resistant grade, also require such material to have environmental-protecting performance.
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 environment-friendly type motor lead, can adapt to multiple different operational environment, and have the performances such as pliability, resistance to wear, the feature of environmental protection, long-life, and stronger overload capacity is arranged.
To achieve these goals, the technical solution adopted in the utility model is: a kind of environment-friendly type motor lead, comprise conductor, separator, insulating barrier and external sheath layer, described conductor is twisted by bundle by silver-gilt copper wire and burst strand is compound strandedly consists of, be disposed with separator and insulating barrier and form insulated wire cores outside conductor, insulated wire cores is outside equipped with external sheath layer, and its insulating barrier adopts polyolefine material.
Preferably, described external sheath layer is extruded outside insulated wire cores 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; Conductor structurally adopts orthodox beam strand, strand strand composite construction, and symmetrical configuration makes that electric wire is stressed in BENDING PROCESS evenly to be stablized; Its insulating barrier is to adopt polyolefine material soft, high mechanical properties, makes electric wire 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.The utility model can adapt to multiple different operational environment, and has the performances such as pliability, resistance to wear, the feature of environmental protection, long-life, and stronger overload capacity is arranged.
Description of drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1, conductor; 2, separator; 3, insulating barrier; 4, external sheath layer.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, environment-friendly type motor lead of the present utility model, comprise conductor 1, separator 2, insulating barrier 3 and external sheath layer 4, described conductor 1 is twisted by bundle by silver-gilt copper wire and burst strand is compound strandedly consists of, be disposed with separator 2 and insulating barrier 3 formation insulated wire cores outside conductor 1, insulated wire cores is outside equipped with external sheath layer 4, and its insulating barrier 3 adopts polyolefine material.Described external sheath layer 4 is extruded outside insulated wire cores 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.
