Abstract
A high/low temperature-resistance aluminum alloy power cable is provided. The high/low temperature-resistance aluminum alloy power cable is especially suitable for high/low temperature-resistance oil-resistance occasions of which the rated voltage is 3kV or below 3kV. Firstly, 8030 aluminum alloy conductors are pressingly wrapped with silicon rubber or F46 insulating layers, wherein the silicon rubber should be vulcanized; an isolating layer is made of a silicon rubber material; an armoring layer is made of aluminum alloy tapes in an interlocking and armoring manner; and an outer protective layer is made of elastic materials such as anti-tear silicone rubber or butyronitrile. According to the high/low temperature-resistance aluminum alloy power cable of the utility model, the conductors are made of aluminum alloys, and therefore, construction cost of users can be is reduced; the insulating layers are made of the silicone rubber with special properties and an F46 material, and therefore, the cable has high temperature-resistance, oil-resistance and low temperature-resistance properties; the armoring layer is made of the aluminum alloy tapes in an interlocking and armoring manner, and therefore, the cable has excellent flexibility; and the outer protective layer is made of the anti-tear silicone rubber or the butyronitrile, and therefore, the cable has excellent oil-resistance and heat-resistance performances.
Description
Technical field
The utility model is a kind of power cable, particularly a kind of high-and low-temperature resistance aluminium alloy electric power cable.
Background technology
Along with international copper valency one tunnel is high, China many wires and cables industries manufacturer suffers untold misery.A few days ago, the Senior Expert of China's non-ferrous metal industry represents that the aluminium of electric wire is a kind of development trend for copper, has got long long way to go but will reach desirable effect.Expert's sound, not only pointed out the problem that wires and cables industry exists, affirmed also that simultaneously aluminium is that inevitable choice China of industry development is the country of a copper shortage of resources for copper, smart copper output capacity only has 40% again, wherein electric equipment products has accounted for copper resource consumption 25%, and the reserves of aluminium are abundant and price is low, do substitute products with aluminium, become the outlet of a lot of industries.The seventies in 20th century, aluminium appears at automobile radiators (water tank) market first for copper, has realized the replacing whole of car now substantially; U.S. aluminium chairman Bel in 2006 reaches in the said firm's financial report second quarter videoconference and represents that more clearly the heat exchanger product adopts aluminum fully, thus they just US and European all newly-built factory.In household electric appliances, the air-conditioning Cu-Al connecting pipe this, 12 tame large-size air conditioning enterprise consumption figures were 1,000 ten thousand covers in 2007,1.1 ten thousand tons of instead of copper; And according to international KFB survey report, comprise out profit, LG, Japan how long enterprise, global air-conditioning Cu-Al connecting pipe utilization rate 55% in 2007.
Be developed into " high-and low-temperature resistance aluminium alloy electric power cable " by scientific research, have bigger application value, can play the purpose of " with aluminium for copper ", greatly save China's copper resource in short supply and create huge economic and social benefits.Different with traditional copper core cable, this aluminium alloy cable adopts high-elongation aluminum alloy material, in fine aluminium, pass through to add materials such as iron, and through the stranded technology of overcompaction and special annealing in process, the space in the alloy aluminum " extruding " totally reduced sectional area and have pliability preferably; Insulating material adopts silicon rubber or fluoroplastics, adopts the braided steel wire sheathed structure.
According to expert introduction, this high-and low-temperature resistance aluminium alloy cable security performance is better than the copper core cable, when its surface contacts with air, with forming a kind of thin and firm oxide layer, can tolerate various corrosion.Produce high-strength croop property because added iron, even at long term overloading with when overheated, also can guarantee to connect stable.
In addition, the ballistic properties of this aluminium cable is littler by 40% than copper cable, and flexility is higher by 24% than copper cable, because the weight of high-and low-temperature resistance aluminium alloy cable only is 50% of copper cable, also can effectively reduce installation cost.
It is reported that the aluminium alloy cable is because the advanced technology maturation is widely used in the many famous engineering projects in the world, as Atlanta Olympic Games venue, conference and exhibition center, Washington, airport, New York etc.Use shows, according to the aluminium alloy cable of code requirement production and installation any fault takes place never in use.
Summary of the invention
The purpose of this utility model provides a kind of performance such as high temperature resistant, low temperature resistant, oil resistant that both had, and it is good and the high-and low-temperature resistance aluminium alloy electric power cable of multinomial characteristics such as excellent mechanical performance, security performance, switching performance arranged to have economic performance again.
The purpose of this utility model realizes by following technical proposals, a kind of high-and low-temperature resistance aluminium alloy electric power cable, comprise conductor, insulating barrier, separator and outer jacket, extruded insulation layer on conductor, wherein insulating barrier is made by silicon rubber or F46 material, and silicon rubber should vulcanize, and outer jacket is selected materials such as tear-proof silicon rubber or butyronitrile for use.
Preferably, conductor adopts 8030 aluminum alloy materials to be made.
Preferably, the extruded insulation layer forms cable core on conductor, and high temperature resistant nonwoven fabrics lapping layer is arranged outside cable core, and lapping layer is in separator.
Preferably, be provided with armour between separator and the outer jacket, armour aluminium alloy interlocking armouring.
Preferably, separator is selected silastic material for use.
The beneficial effects of the utility model are: insulating barrier is selected silicon rubber and the F46 material with property for use, makes cable have high temperature resistant, oil resistant, performance such as low temperature resistant; Outer jacket adopts tear-proof silicon rubber or butyronitrile material to have excellent oil resistant, heat resistance; Conductor adopts 8030 aluminium alloys to reduce user's construction cost greatly; Armour adopts lock armo, makes cable have flexibility preferably.This cable is specially adapted to rated voltage 3kV and following high-low temperature resistant, oil resistant occasion power cable.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model.
Among the figure: 1, conductor, 2, insulating barrier, 3, fill, 4. lapping layer, 5, separator, 6, armour, 7, outer jacket.
Embodiment
As shown in Figure 1: extrude silicon rubber or F46 insulating barrier 2 at conductor 1; Add during the insulated wire cores stranding and fill 3; High temperature resistant nonwoven fabrics lapping layer 4 is arranged outside cable core then; Lapping layer has separator 5 outward; Aluminum alloy strip lock armo layer 6 is arranged outside the separator 5; Armour has outer jacket 7 outward.
