Introduction

What is Aluminum Alloy Cable

Aluminum Alloy Power Cable, a new kind material power cable which based on AA-8000 series aluminum alloy conductor, adopted the special compacted process and annealing technology.

Differences between Aluminum Alloy Cable and other cables

Aluminum Alloy Cable based on AA-8000 series aluminum alloy conductor, while other cables are just copper or aluminum conductor.

Why should we using Aluminum Alloy Cable ?

1、high copper price increases the investment cost, while using Aluminum Alloy Cable could save about 30% cost in cable construction. In addition, China is lack of copper resources, over 70% of the copper rely on foreign imports, “to save copper with aluminum” is the long-term development policy.

2、Aluminum Alloy Cable is lighter and smaller in bend radius, so it can reduce construction costs and decrease the deterioration of equipment and cable, makes installation easier.

3、Inter Locked Armored Cable can eliminates the bridge or tube, thus further savings in the cost of materials and construction.

Advantages

1、conductivity:

The conductivity of Jiangsu Changfeng Aluminum Alloy Cable equals to 62.5% of IACS, and the current capacity equals to 79% of copper conductor, better than pure aluminum conductor.

2、creep resistance

The annealing process of aluminum alloy conductor reduces the tendency to "creep" of the conductor under the heat and pressure, the creep rate only equals to 1/15 of pure aluminum, and consistent with copper conductor.

3、Tensile strength and elongation

Aluminum alloy conductor using a special process, and added a special ingredient, compared to pure aluminum conductor, the tensile strength and elongation has been increased 30%, the use of more secure and reliable.

4、Expansivity

The thermal expansion coefficient is used to calculate the size of the material changes when the temperature changes, the thermal expansion coefficient of aluminum alloy is close to copper, while the majority of electrical connector are made of aluminum, which is particularly suitable for aluminum alloy. Therefore, the expansion and contraction of the aluminum alloy conductor is completely consistent with the connector.

5、strong bearing capacity

the tensile strength of Aluminum alloy material has been improved, aluminum alloy cable can bear the weight of a length of 4000 m, while copper cable can only bear the 2750 meters, this advantage is particularly obvious in the construction of large span wiring (such as sports stadiums).

6. Anti-corrosive capacity

The reason of the anti-corrosive capacity inherent in aluminum is when aluminum is exposed to air, there will be a thin and firm oxide layer on the surface of aluminum, which can resist corrosion in any forms.Moreover,the rare earth element, added in aluminum alloy, can further improve the anti-corrosive capacity of aluminum, especially electrochemical corrosion.In the condition of sulphur, such as railway tunnel and other similar places, the anti-corrosive capacity of aluminum alloy is better than that of copper.

7.Flexibility

Aluminum alloy has very good bending property because its special alloy ingredients and processing can largely improve its flexibility. Aluminum alloy is 30% higher than copper in flexibility, 40% lower in resiliency. Generally speaking, the bending radius of copper cable is 10 to 20 times than outside diameter, but aluminum alloy is 7 times, which makes it easier to connect terminals.

8. Armour property

Most of commonly-used armoured cables in China is steel tape armoured,

whose security level is very low. When those cables suffer from external destructive force, it is very easy to be punctured as its resistance is very bad. And steel tape armoured cables weigh heavily,so the cost of installation is relatively high. According to the above, adding their bad anti-corrosive capacities,steel tape armoured cables have a short service life. However, our aluminum alloy chain armoured cables,in accordance with American standard,have chain structure between layers,which makes the cables resist strong external destructive force.As a result, even though the cables suffer from large pressure and impact force, it is not easy for them to be punctured,which improve security capacity.Meanwhile, as armoured structure isolates cables from the external,even in the condition of fire,the armoured layer improves the flame- retardant and fire-resistant level of cables and lower danger coefficient of fire.

We not only make improves conductors in material capacities, but also have great breakthrough in technology.We apply special compress technology and makes the compression coefficient 0.93, which is the best in domestic.The compression in the largest extension can make up the insufficiency of aluminum alloy in bulk electrical conductivity because it makes stranded wires conductor similar to solid conductor,which obviously reduces external diameter of core of conductor,which makes the external diameter of conductor about 10% more than copper cables in the condition of same current-carrying capacity,thus improves conductivity.

Advantages of aluminum alloy cables of Jiangsu Changfeng Cable Co.,Ltd.
