Creep resistance performance
The alloy material and annealing process of high conductivity alloy cables reduce the tendency of conductors to "creep" under heating and pressure. Compared to pure cables, the creep resistance can be increased by 300%, avoiding relaxation problems caused by cold flow or creep.
Tensile strength and elongation
Compared to pure cable conductors, high conductivity alloy cables greatly improve their tensile strength and elongation by 30% due to the addition of special components and the use of special processing techniques, making them safer and more reliable to use.
Coefficient of thermal expansion
The coefficient of thermal expansion is used to calculate the size change of a material during temperature changes. The thermal expansion coefficient of alloy cables is equivalent to that of copper. For many years, aluminum connectors have been reliably used for copper and aluminum conductors, and most of the electrical connectors used today are made of aluminum, which is particularly suitable for alloy cables. So the expansion and contraction of high conductivity alloy cables and connectors are completely consistent.
Connection performance
Electrical connections made with alloy cables are as safe and stable as those made with copper conductors. The composition of cable alloy greatly improves its connection performance. When the conductor is annealed, the added iron produces high-strength anti creep performance, ensuring stable connection even in long-term overload and overheating.
Strong self weight bearing capacity
Cable alloy improves the tensile strength of pure cables. Alloy cables can support a self weight of 4000 meters, while ordinary cables can only support 2750 meters. This advantage is particularly prominent in the wiring of large-span buildings (such as sports venues).
Anti corrosion performance
The inherent anti-corrosion performance comes from the formation of a thin and sturdy oxide layer when the aluminum surface comes into contact with 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 alloys, especially electrochemical corrosion. Its ability to withstand harsh environments makes it widely used as a conductor for cables in trays, as well as many industrial components and containers. The occurrence of corrosion is usually related to the connection of different metals in humid environments, and corresponding protective measures can be used to prevent corrosion, such as using lubricating oil, antioxidants, and protective coatings. Alkaline soil and certain types of acidic soil environments have significant corrosiveness to aluminum, so aluminum conductors buried directly should use insulation layers or molded sheaths to prevent corrosion. In sulfur-containing environments, such as railway tunnels and similar places, alloys have significantly better corrosion resistance than copper.
Flexibility
Alloy has excellent bending performance, and its unique alloy formula and processing technology greatly improve flexibility. Aluminum alloy has a 30% higher flexibility and a 40% lower rebound strength than copper. The bending radius of a typical copper cable is 10-20 times the outer diameter, while the bending radius of an alloy cable is only 7 times the outer diameter, making it easier to connect terminals.
