Abstract
The utility model relates to a lead wire of double layer insulation and double layer knitting motor winding, comprising a conductor, a knitting layer and an insulating layer, wherein the outside of the conductor is sequentially covered by a knitting inner layer, a polyfluortetraethylene insulating layer, a polyester insulating layer and a knitting outer layer. The utility model has the advantages of simple structure, the outside of the conductor is covered by two insulating layers and two polyester yarn knitting layers, and the conductor is a wire harness composed of a plurality of hinged copper wires having fine diameters, thereby effectively increasing the electrical insulativity, the resistance to high temperature and the ageing resistance of the conducting wires. Further, the utility model has high enduring ability to various environment factors and is a novel lead wire of motor winding with high innovation.
Description
Technical field
The utility model belongs to field of cables, especially a kind of double hyer insulation double braid motor windings lead wire.
Background technology
The motor windings lead wire is a kind of more special electric wire, insulating material as the motor windings lead wire was to adopt polyolefine material, elastomeric material or insulating varnish in the past, but the motor windings lead wire that adopts this insulating material is not very good in performance aspect moisture-resistant, the resistance to elevated temperatures, have in addition adhesion phenomenon appears.The application example of fluoro-containing plastic as the lead wire insulating barrier appearred adopting in recent years, make the insulation property and the resistance to elevated temperatures of this class lead wire be improved, this is because fluoro-containing plastic is compared with other plastics, have characteristics such as more excellent high temperature resistant, corrosion-resistant, electric insulating quality, wherein the performance with polytetrafluoroethylene is the most outstanding especially.Polytetrafluoroethylene is used as the moulding of wire cable insulating and generally comprised two kinds of methods: a kind of is wrapped polytetrafluoroethylene film, sinter molding then on lead; Another kind is a plain conductor dip-coating polytetrafluoroethylene teflon soliquoid, dries sinter molding then.Motor windings lead wire of the prior art; no matter adopt rubber, insulating varnish still to adopt polytetrafluoroethylene as insulating barrier; all be monolayer insulating layer and individual layer net protective layer, be subjected to the influence of various factorss such as extraneous mechanism, physical-chemical effect or heat, wet, microbe and influence the normal use of lead unavoidably like this.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of tolerance and strong double hyer insulation double braid motor windings lead wire of ageing resistace that can effectively improve various environmental factors is provided.
The utility model is achieved through the following technical solutions:
This double hyer insulation double braid motor windings lead wire is made of conductor, braid, insulating barrier, it is characterized in that: conductor is coated with braiding internal layer, teflon insulation layer, polyester insulated layer and woven outer layer outward successively.
And described conductor is that the tiny copper cash of many diameters is through the stranded wire harness that forms.
And described braiding internal layer and woven outer layer all are the dacron threads that formed by braiding after the purification process.
Advantage of the present utility model and good effect are:
1. this lead wire has adopted the structure that is coated with dielectric layers and two-layer dacron thread braid at conductor, has effectively improved the electric insulating quality and the resistance to elevated temperatures of lead, strengthens the ageing resistance of lead.
2. the copper cash that many diameters of the conductor of this lead wire employing are tiny has improved the flexibility of lead through the stranded wire harness that forms.
3. the utility model overall structure is very simple, and is stronger to the tolerance and the ageing resistace of various environmental factors, is a kind of New-type electric machine winding lead wire with higher innovation performance.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described, but is not limited to the concrete structure that present embodiment is narrated.
This double hyer insulation double braid motor windings lead wire is the coaxial cable form, is coated with braiding internal layer 4, teflon insulation layer 3, polyester insulated layer 2 and woven outer layer 1 outside the conductor 5 of axle core successively.Wherein:
Conductor is that the many tiny copper cash of diameter constitute through the stranded wire harness that forms, and its objective is in order to improve the flexibility of lead.
Braiding internal layer and woven outer layer all are the dacron threads that formed by braiding after the purification process, can effectively improve the resistance to elevated temperatures of lead wire, and strengthen the ageing resistance of lead.
Be teflon insulation layer and polyester insulated layer between braiding internal layer and woven outer layer, the teflon insulation layer twines with polytetrafluoroethylene film, is first insulating barrier; The outer wrapped polyester insulated layer of teflon insulation layer twines with the polyester belt film, is second insulating barrier, and the main insulating layer of it and teflon insulation layer mutual group cost motor windings lead wire can effectively improve the insulation property of lead wire.
