Abstract
The utility model relates to a copper-clad-aluminum zirconium-alloy wire cable, comprising a conductive core and an isolation sleeve clad on the conductive core, wherein the conductive core comprises an aluminium-zirconium alloy conductor and a copper coated layer clad outside of the aluminium-zirconium alloy conductor. The beneficial effects of the zirconium-alloy wire cable are that the zirconium-alloy wire cable has excellent conductive performance, a copper material is saved, intensity is relatively high, heat resistance temperature is high and compatibilization problem is effectively solved.
Description
Technical field
The utility model relates to a kind of copper cover aluminum zircaloy line cable.
Background technology
The best metal material of occurring in nature conduction is silver, is copper and aluminium then.Because silver belongs to precious metal, can not use as industrial cable on a large scale, so copper just becomes the conductive metallic material that is most widely used.Produce cable and always make inner wire with fine copper, the weight of copper accounts for 70～75% of cable total weight.Conducting electricity very well of copper, toughness is good, but price is more expensive than aluminium, and also more rare.Under the situation international, that domestic amount of copper consuming constantly rises, the copper resource gets over shortage, adds human factor, the copper valency rises violently, high, form a series of rise in price reflections, force cable industry actively to seek new conductor material and come the instead of pure copper cash to make the inner wire of cable.
Along with the continuous increase of town and country power consumption, the increase-volume problem sternness of the old and new's circuit, China mainly adopts at present increases cross-sectional area of conductor solution increase-volume problem, because the cable cross section is strengthened, must rebuild for establishing circuit, and difficulty of construction is big, and expense is big.Adopting the fire resistant aluminum alloy increase-volume is to realize that by the heat resisting temperature that improves conductor difficulty of construction and expense are few.
The utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provide a kind of copper cover aluminum zircaloy line cable.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of copper cover aluminum zircaloy line cable, the separation sleeve that comprises conductor wire core and coated with conductive core, conductor wire core comprise aluminium zircaloy conductor and are coated on the copper clad of aluminium zircaloy conductor outside.
Further, separation sleeve comprises insulating barrier, fire-retardant belting layer and restrictive coating from the inside to surface successively.
Further, the insulating barrier material is crosslinked polyethylene or silicon rubber.
Further, the restrictive coating material is that polyvinyl chloride or fourth are fine.
Further, the diameter of conductor wire core is 0.2～0.7mm.
The beneficial effects of the utility model are: have excellent conducting performance, and save the copper material, intensity is higher, and the heat resisting temperature height effectively solves the increase-volume problem.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Wherein: 1. aluminium zircaloy conductor, 2. copper clad, 3. insulating barrier, 4. fire-retardant belting layer, 5. restrictive coating.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of copper cover aluminum zircaloy line cable as shown in Figure 1 comprises that the separation sleeve of conductor wire core and coated with conductive core, conductor wire core comprise aluminium zircaloy conductor 1 and be coated on the copper clad 2 of aluminium zircaloy conductor 1 outside.Separation sleeve comprises insulating barrier 3, fire-retardant belting layer 4 and restrictive coating 5 from the inside to surface successively.Insulating barrier 3 is coated on copper clad 2 outsides, and fire-retardant belting layer 4 is coated on insulating barrier 3 outsides, and restrictive coating 5 is coated on fire-retardant belting layer 4 outsides.
Insulating barrier 3 materials are crosslinked polyethylene or silicon rubber, and restrictive coating 5 materials are that polyvinyl chloride or fourth are fine.
The diameter of conductor wire core is 0.2～0.7mm, and the conductor wire core flexility that diameter is thinner is better.
Fire-retardant belting layer 4 is the low smoke and zero halogen material, can play isolate conductive core and the extraneous effect that contacts on the one hand, makes after tightly wrapping on the other hand that the structure of conductor wire core is more compact.
Be enlightenment with above-mentioned foundation desirable embodiment of the present utility model, by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
