Abstract
The utility model discloses an aluminum alloy conductor cable comprising a line core; and the line core comprises an aluminum alloy conductor and an insulating layer squeezed outside the aluminum alloy conductor. A cable core is stranded by more than two line cores, a liner layer is wrapped outside the cable core, an interlocking armored layer is wrapped outside the liner layer, and an outer sheath layer is squeezed outside the armored layer. The aluminum alloy conductor cable has excellent and scientific material selection, has excellent performance, can better substitute a copper conductor cable, and is a solution to the problems of easy oxidation and poor creep resistance of electric pure aluminum conductors and the like; the aluminum alloy conductor cable has excellent flexibility, excellent abrasion resistance, weatherability and higher fire prevention performance due to the use of aluminum interlocking armors; so that the durability and the service life of the cable can be greatly improved and can be used under severe environmental conditions and special use places; and a product contains no toxic element, and has little smog produced during combustion and good environment-friendly performance.
Description
Technical field
The utility model relates to the cable technology field, specifically is a kind of aluminium alloy conductor cable.
Background technology
China is in 50～seventies of last century, and copper is as strategic resource, and the state basic policy of electrical applications aspect is exactly " with an aluminium for copper ", and copper cable can not use in civil buildings, and employed cable conductor mostly is electrician's fine aluminium conductor greatly; To the mid-80, aluminium conductor cable problem in use comes out, especially the oxidation of aluminum conductor joint causes a lot of fire etc. that rise, and copper, aluminium price difference were little at that time, copper conductor becomes based on copper on using gradually in the superiority of aspect of performance such as electric, mechanical, durable in addition; To 90 later years, multinomial national standard, standard also require to adopt copper cable in civil buildings, and aluminium conductor is basic just not to have been adopted.But recent years, particularly since 2005, the copper metal price ascensional range of international market is very big.Since 2005; copper increases to 9000 dollars/ton from 2000 dollars/ton; economic crisis in 2008; the copper valency is fallen from 9000 dollars/ton get back to 3000 dollars/ton; yet 2009, the copper valency increased to 8000 dollars/ton from 3000 dollars/ton again, in by the end of December, 2010; international copper valency records high again, and copper valency per ton is above 9500 dollars.The pressure that expands along with national currency in recent years increases suddenly, and the copper valency also has strong up-trend, and copper product shared cost in copper cable reaches more than 70%, and the price of copper cable is also being risen at the sound, thereby causes user's input cost significantly to increase.In the face of constantly soaring copper valency, and following unpredictalbe upward price trend, many clients begin to select cheap aluminium cable.Because aluminium is very high at natural content, the price of aluminum current material is equivalent to about 1/3rd of copper.Not only aspect raw material supply, there is advantage, at manufacture view, the cable of a same length, required aluminium important also lighter than copper generally can light 30-50%, therefore, in whole transportation and installation process, has also brought the effect of energy-conserving and environment-protective for the client.See with the existing market situation, become inevitable choice again for copper with " aluminium ".
Because existing electrician's fine aluminium cable easily produces oxidation, corrosion, thereby cause problems such as joint is on fire, need research to use a kind of novel aluminum conductor, improve the reliability of aluminium cable to solve this type of problem.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of cost advantage that has is provided, the aluminium alloy conductor cable of energy-conserving and environment-protective when making simultaneously.
The utility model discloses a kind of aluminium alloy conductor cable, comprise the core that the insulating barrier that extruded by aluminium alloy conductor and aluminium alloy conductor constitutes outward, be twisted into cable core by core more than two strands, wrapped inner covering outside cable core, wrapped chain armour extrudes external sheath layer outside armour outside inner covering.
In the utility model because conductor is an aluminium alloy conductor, and the conductor resistance rate can reach 62% of International Annealed Copper Standard (IACS), advantage such as possess that creep-resistant property is good, antiseptic property and pliability are good.Insulating barrier adopts cross-linking polyethylene materials, and inner covering is wrapped nonwoven fabric belts or high flame retardant glass fibre carrying material, and armour is that aluminum alloy strip or the chain armouring of steel band are wrapped, and external sheath layer is for extruding the low smoke, zero halogen environment-friendly polyolefin material.
A kind of novel aluminum alloy conductor cable described in the utility model is simple in structure, selection is good, science, properties of product are good, Alloy instead of Copper conductor cable preferably, and the easy oxidation of solution electrician's fine aluminium conductor, problems such as creep-resistant property difference, it uses the chain armouring of aluminium alloy to have fabulous pliability, good resistance to wear and weatherability, and possesses stronger fire protecting performance, can improve the durability and the useful life of cable greatly, can under harsh environmental conditions and under the special use occasion, use, product does not contain the toxicity element, and the smog that produces when burning is few, possesses good environmental-protecting performance.
Description of drawings
Be illustrated as the cross section structure schematic diagram of 4 core aluminium alloy conductor cables of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in the figure, aluminium alloy conductor cable described in the utility model, on aluminium alloy conductor 1, extrude single core insulation core that crosslinked polyetylene insulated layer 2 constitutes, carry out stranded stranding by four eradication edge cores then and form cable core, wrapped glass fibre belt 3 outside cable core, wrapped chain armour 4 on inner covering 3 extrudes low smoke, zero halogen environment-friendly polyolefin external sheath layer 5 then on armour 4.
The utility model provides a kind of thinking and method of aluminium alloy conductor cable; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.The all available prior art of each component part not clear and definite in the present embodiment is realized.
