1, electrical conductivity: the conductivity of aluminum alloy is the most commonly used reference material of copper IACS 61.5%, the flow rate of copper is 79%, better than pure aluminum standard.
2, creep properties: Aluminum Alloy conductor alloy materials and annealing process reduces the conductor in the heat and pressure under the "creep" tendency, compared with pure aluminum, creep resistance can be improved by 300%, to avoid the problems caused by cold flow or relaxation creep.
3, the tensile strength and elongation: Aluminum Alloy conductor compared to the pure aluminum conductor, due to the special composition and special processing technology, greatly improves the tensile strength and elongation rate increased to 30%, the use of more safe and reliable.
4, the coefficient of thermal expansion: thermal expansion coefficient is used to calculate the temperature changes in the size of the material changes. The thermal expansion coefficient of aluminum alloy is similar to that of copper. For many years, aluminum connectors have been used reliably in copper and aluminum conductors, and most of the electrical connectors used today are made of aluminum. Therefore, the expansion and contraction of aluminum alloy conductor and connector are identical.
5, self bearing capacity of aluminum alloy to improve the tensile strength of pure aluminum, aluminum alloy cable can support the weight of 4000 meters length, copper cable can only support the 2750 meters. This advantage is particularly prominent in the construction of large span buildings (such as stadiums).
6. The corrosion resistance of aluminum is inherent in the formation of a thin, solid oxide layer when the aluminum surface is in contact with the air, which is particularly resistant to various forms of corrosion. The addition of rare earth elements in the alloy can further improve the corrosion resistance of aluminum alloy. Aluminum can withstand the harsh environment of the characteristics of the cable is widely used in the tray of the conductor, as well as many industrial components and containers. Corrosion is often associated with the connection of different metals in a wet environment, and appropriate protective measures can be used to prevent corrosion, such as the use of lubricants, antioxidants, and protective coatings. Alkaline soil and some types of acidic soil environment has a greater corrosion of aluminum, so directly buried aluminum conductor should be used to prevent the corrosion of the insulation layer or molded sheath.  The corrosion resistance of aluminum alloys is much better than that of copper in sulfur containing environments, such as railway tunnels and other similar areas.
7, flexible aluminum alloy has a good bending performance, its unique alloy formula, processing technology, so that flexibility greatly improved. Aluminum alloy is 30% higher than copper flexibility, rebound is lower than the copper of 40%. General cable bending radius is 10~20 times of the outer diameter and Aluminum Alloy bending radius is only 7 times the diameter, easy terminal connection.
8, the common characteristics of armoured armoured cable, mostly adopts steel tape armouring, low security level, under the outside force damage, its ability to withstand the poor, easily lead to breakdown, and weight, the installation cost is quite high, and poor corrosion resistance, service life is not long. We according to the American Standard metal armored cable chain development, using the Aluminum Alloy with chain armour, the chain structure between layer and layer, ensure the cable can withstand strong external force damage, even if the cable suffered bigger pressure and impact force when the cable is not easy to breakdown, and improve safety performance. At the same time, the cable structure is isolated from the outside world, and even when the fire occurs, the armored layer improves the fire resistance and fire resistance level of the cable, thereby reducing the fire risk factor. Aluminum alloy with the structure of armored steel tape armored, light weight, easy to install, can avoid the installation of bridge, can reduce the installation cost of 20%~40%. According to the use of different places can choose different sheath layer, so that the use of armored cable more widely.
9, pressed from the characteristics of single volume conductivity into Aluminum Alloy than copper conductor, but we developed not only from material performance improvements, but also achieve a major breakthrough in the process, we use the compact ultra conventional technology, the compression coefficient reached 0.93, while the tight line shaped pressure coefficient can reach 0.95, the first of its kind in china. Pressed by maximum limit, you can make up for lack of Aluminum Alloy in bulk conductivity of the stranded conductor wire core such as solid conductor, significantly reduce the wire diameter, increase the conductivity, under the same load flow conditions only 10% larger than copper wire conductor.
