Aluminum Alloy Cable Industry Comprehensive Analysis

admin — Sat, 21 Mar 2015 11:41:00 +0000

Wu Changshun, director of the national electric wire electric cable quality supervision and inspection center has done the detailed introduction of aluminum alloy superiority, he said: "the increase in aluminum alloy conductor is through a trace of the elements such as iron, silicon, zinc, and after processing of alloy materials, greatly improved the bending of aluminum, corrosion resistance, mechanical processing, heat resistant, mechanical strength, such as performance, so as to avoid the existence of pure aluminum conductor cable connections is not the problem of low stability and mechanical properties. Compared with copper cable, its security and load flow, electrical conductivity and safety, conductor resistance rate, especially the amount of intercepting identical even better than the traditional copper cable, made up for hard pure aluminium as many deficiencies of cable conductors, solved the aluminium cable in security properties, electrical properties, mechanical properties of major technical problems".
And in addition to superior performance, the cost advantage to wire and cable manufacturers to be reckoned with. It is reported, as the main part of power cable conductor, in low voltage power cables of cable around 70% – 70% of the cost of raw materials. And aluminum alloy cable on the cost of obvious advantages compared with copper core cable. In addition, in the same electric conductivity, the weight of the aluminum alloy cable was only 50% of the copper cable, so in engineering installation and reduce the transportation cost is also has the certain superiority.
Aluminum alloy cable is becoming China's cable companies eyeing a blue ocean. Aluminum alloy cable either from the perspective of the cost of production, or from the view point of application category, have a good potential, is most likely in the next few years, instead of copper core cable to become the latest must-haves in the wire and cable manufacturing enterprises.
Aluminum alloy cable imported from North America, China has gained wide acceptance
Since 1968, in the southern United States cable company began the development and production of alloy power cable, then alcan, American famous companies such as UMI electric also engaged in this industry, and in the United States, Canada, Mexico and other countries began to popularization and application. Mainly used in airports, military bases, office buildings, residential, hotels, supermarkets, schools, stadiums, hospitals, factories and other plant construction project. North American successful application of alloy cable nearly 50 years, had never seen any safety accident. It is fast in Europe and the application of new materials alloy electric power cable is one of the important reasons.
Now aluminum alloy cable is not new in China, its performance, price advantages and after years of the testing authority and market inspection. Statistics show that although at present in China copper core cable still accounts for more than 90% of the market. But that did not stop aluminum alloy cable for the masses gradually accepted, accept the good momentum.
Aluminum alloy cable development future is limitless
The United States, Canada and other wire and cable manufacturing giant production, the use of aluminum alloy cable has nearly 50 years, and aluminum alloy cable also because of its excellent electrical properties.

Copper Clad Aluminum And Copper Material Performance Comparison

admin — Fri, 20 Mar 2015 11:39:00 +0000

Cable according to the different inner conductor, there are two main types, one is pure copper material, another is a kind of copper clad aluminum material.
Copper clad aluminum in the aluminum or aluminum/steel alloy copper core material surface with pericardium, by drawing, copper layer thickness above 0.55 mm. Due to the high frequency signal transmission on the conductor with the characteristics of the skin effect, cable TV signal in the 0.008 mm above the surface of the copper layer, copper clad aluminum inner conductor can completely meet the requirements of signal transmission, the transmission properties of the signal is consistent with the same diameter copper body.
Copper clad aluminum composite wire first launched in 30 s of the last century by the German, then in Britain, the United States, France and other countries to promote, widely used in various fields. The CATV cable as early as 1968 began trial copper clad aluminum wire, consumption quantity of 30000 tons/year. American states have now with copper clad aluminum (steel) cable instead of the pure copper cable. In recent years, China's copper clad aluminum CATV cable also began to be a large number of use.
Copper clad aluminum and pure copper can be compare the following three aspects:
Mechanical properties:
Pure copper conductor strength, elongation, larger than the copper clad aluminum conductor is pure copper in mechanical performance is better than copper clad aluminum. From the perspective of cable design, pure copper conductors than copper clad aluminum conductor mechanical strength good advantages, in the process of practical application does not necessarily need to. Copper clad aluminum conductor, much lighter than pure copper, so copper clad aluminum cable on the overall weight is lighter than pure copper conductor cable, this will give the transport of the cable and cable erection construction convenient. Other than pure copper soft copper clad aluminum, copper clad aluminum conductor cable production in terms of flexible cable is better than pure copper.
Electrical properties:
Because poor than copper, the conductivity of aluminium made of copper clad aluminum conductor dc resistance than pure copper conductor, this presence of influence mainly in 2014 mid-term exam sprint comprehensive review guide exam in Beijing Guangdong area test Jiangsu region try to see if the cable is with power supply, such as supplies power to the amplifier, if be used to power supply, copper clad aluminum conductor will lead to additional power consumption, voltage lower more. When more than 5 MHZ frequency, at this time of ac resistance attenuation under the two different conductor has no significant difference between the two. Of course, this is mainly because the skin effect of high frequency current, the higher the frequency, the flow of electric current is more close to the conductor surface, on the surface of copper clad aluminum conductor in pure copper material, at some point when the frequency is high, the current to flow in copper plating quality inside. In the case of 5 MHZ, the current flow in the 0.025 mm thickness of near surface, the thickness of copper and copper clad aluminum conductor thickness is about twice as many than that. For coaxial cable, because the signal transmission is above 5 MHZ, so the copper clad aluminum conductor and pure copper conductor transmission effect is the same. In the actual test the attenuation of the cable to prove it.
Copper clad aluminum conductor is pure copper, in the process of production easier for straightening processing, thus to some extent, can say with copper clad aluminum cable than in pure copper conductor cable good return loss index.
Economical:
Copper clad aluminum conductor are sold by weight, of pure copper conductor is sold by weight, the price of copper clad aluminum conductor is more expensive than the same weight of pure copper conductor. But the same weight of copper clad aluminum conductor length is much longer than pure copper, and is calculated on the length of the cable. Same weight copper clad aluminum wire is 2.5 times that of the copper wire length, the price is just more than a few hundred yuan per ton. Comprehensive, copper clad aluminum would be advantage. Because of the copper clad aluminum cable comparatively light, and the transportation cost of the cable, erectness cost will be reduced, can bring certain convenience to construction.
Easy maintenance.
Use copper clad aluminum can reduce network failure, avoid network personnel in the maintenance of "cut core in winter, summer cut skin" (aluminum or aluminum tube with longitudinal bag products). Due to the copper aluminum inner conductor and outer conductor of the cable thermal expansion coefficient is large, in the hot summer, aluminum outer conductor for large, copper inner conductor relative retraction, not fully come into contact with the elastic contact within F head block; Outside in the cold winter, aluminum conductor shrinkage is larger, the shield falls off. When in the coaxial cable with copper clad aluminum conductor, it differ with aluminum outer conductor thermal expansion coefficient is small, the temperature changes, greatly reduced the cable core pulling fault, improve the quality of the network transmission.
The wire and cable industry with copper clad aluminum wire is also a good way to alleviate the pressure of the present enterprise. Aluminium wire outside the bread a layer of copper by the control of double metal wire, because with a small specific gravity, as well as good transmission performance, particularly applicable to do the inner conductor of the coaxial cable of the radio frequency, compared with pure copper wire, its density is 40% pure copper. And transfer characteristic is better than that of pure copper wire, is the ideal of the coaxial cable of the radio frequency branch line of inner conductor. In general, copper clad aluminum conductor overall performance is better than pure copper conductor, it will save the cost of the user.

The Definition And The Difference Between Ordinary Cable And Aluminum Alloy Cable

admin — Thu, 01 Jan 2015 11:19:00 +0000

1.The Definition Of Aluminum Alloy Cable
Aluminum alloy power cable, which is AA – 8000 series aluminum alloy materials for conductor, USES special compression technology and annealing treatment, and chain armoring process advanced technology invention of new materials such as power cables.
2, Difference Between Alloy Cable And Ordinary Cable
Metal cable the AA – 8000 series aluminum alloy conductor, while ordinary cable using copper or aluminum as cable conductor.
3, Why To Promote The Use Of Alloy Cable?
Under the same volume, the weight of the aluminum alloy is about a third times of the copper. According to the calculation, on the premise of meet the same conductivity, same weight aluminum alloy cable length is twice the copper cable. Therefore, the same load flow when the weight of the aluminum alloy cable is about half of the copper. Use aluminum instead of copper cable, can reduce cable weight, reduce installation cost, reduce the number of devices and cable wear, make installation work more easily.
4. The Advantage of Alloy Cable compare with Ordinary Cable:
Electrical conductivity:
The conductivity of the aluminum alloy is the most commonly used benchmark material copper 61.5% IACS, carrying capacity is 79% of the copper, is better than that of pure aluminum standards.
