Product Description:


Conductivity Feature


Compare the cable with same specification, conductivity of alloy conductor manufactured by Sinyu company is 62.5% of normal international annealed copper standard (IACS). However, the actual weight of Al is one third of copper with the same volume. According to the calculation, at the premise of meeting requirements of same conductivity, length of alloy cable with the same weight is two times of copper cable. Therefore, the weight of alloy cable is half of copper cable under the same current rating. When the cross section of alloy cable is 1.5 times of copper conductor, the electrical performance is nearly the same. Cable weight could be minimized through alloy cable instead of copper cable. It could reduce the installation cost, minimize abrasion of equipment and cable and it is easy to be installed.


Anti-creepage Feature


   Trend of creepage of metal under heat and pressure is greatly minimized through special alloy formula and heat treatment technology. Stability of Electrical connection by high conductivity alloy conductor is the same as copper conductor.


Thermal Expansion Coefficient


   Thermal expansion coefficient is used to calculate the dimension change of material under temp variation. The thermal expansion coefficient of alloy cable is slightly higher than copper. It has more expansion and shrinkage than copper under change of same temperature.


We recommend using Copper-Al transit connector that connects the high-conductivity alloyed conductor. It has passed 1000 times thermal cycling test specified in GB 9327 (IEC 61238) standard. Reliability of electrical connection is proved. And, it completely solves problems of thermal expansion and copper-Al electrical and chemical corrosion at the connecting point of two kinds of metals by Copper-Al transit connector.


Connection Feature


   The connection feature is largely improved by alloy composition in alloy conductor. That is the basic reason for being approved as ACM conductor material. Iron element enhances the anti-creepage feature. It can guarantee the stability of connection due to long-time overloads and overheat. When the connector, which is subject to 1000 times thermal cycling in GB 9327 standard, it can guarantee long-term stability and reliability of connection. It is not necessary for fastening connection of high conductivity alloy for the reason that it will damage the connection feature.


Mechanical Features


1, Rebound of high-conductivity alloy cable is 40% less than copper cable.


2, Flexibility of high-conductivity alloy cable is 24 more than copper cable.


3, High-conductivity alloy cable has better bending feature and it is easy to be connected.


4, The thermal expansion coefficient of alloy cable is slightly higher than copper. It has more expansion and shrinkage than copper. Therefore, alloy conductor could not be connected by copper connector.





   Anti-corrosion feature of alloy conductor is resulted from thin and tight oxidation layer formed through contact between alloy surface and air. The oxidation layer is resistant to various corrosion. Alloy is expansively applied to cable conductor inside the tray and many industrial components and containers account for resistance to hazard environment. Corrosion is related to connection with various metals under damp environment. Relevant protection measures shall be taken to prevent corrosion. For example, lubricant oil, antioxidant and protection coating can be applied. Insulation or sheath could be applied to buried Al conductor to prevent corrosion. In sulphur environment, such as railway, channel, sewage treatment areas, anti-corrosion feature of alloy is better than copper.
