Extruded insulated power cables with rated voltage up to and including 26-35kVProduct DescriptionProduct DetailsThe new high conductivity aluminum alloy cable has the following advantagesSafety performanceSimilar foreign products in North America, through the authoritative test laboratory "according to long-term operation (more than 30 years) formulated 100 times cold water quenching-cold link joint head thermal cycle test standard". Electrical conductivity Compared with cables of the same specification, the conductivity of highly conductive aluminum alloys is 61.5% of the most commonly used International Annealed Copper Standard (IACS). Under the same volume, the actual weight of aluminum is about one third of that of copper. According to the calculation, the length of a high-conductivity aluminum cable with the same weight is twice that of copper cable under the premise of the same conductivity. As a result, a highly conductive aluminum cable is half the weight of a copper cable carrying the same amount of traffic. Using high-conductivity aluminum cables instead of copper cables can reduce cable weight and installation costs, reducing cable and equipment wear and tear, and making installation easier. Aluminum alloy has excellent electrical conductivity, thermal conductivity and corrosion resistance. Relative conductivity of pure metalsInflation performanceThe coefficient of thermal expansion is used to calculate the size change of a material when the temperature changes. High conductivity aluminum alloy thermal expansion coefficient is slightly higher than copper, it expands or contracts a little more than copper. We recommend the use of copper aluminum transition terminal, the terminal has passed the GB9327(IEC61238)1000 times of thermal cycle test, with a strict test to prove the reliability of alloy cable electrical connection, and the use of copper aluminum transition terminal completely solved the two kinds of metal connection thermal expansion and copper aluminum electrochemical corrosion problems.Resistance to creepThe special alloy formulation and heat treatment process of high conductivity alloys greatly reduce the tendency of the metal to "creep" under heat and pressure. An electrical connection made with a highly conductive aluminum alloy conductor is as stable as a connection made with a copper conductor.Connection performanceThe alloy composition of the high conductivity aluminum alloy core power cable conductor greatly improves the connection performance of the traditional aluminum cable, which is the fundamental reason that it is allowed to be used as the alloy conductor material. Especially when the conductor is preheated, the added iron produces high strength resistance to peristalsis, ensuring connection stability even during long periods of overload and overheating. When a test approved mechanical connector of 90 ° c grade is used, the connector test results at the test facility provided by GeorgiaPower, USA, show that the performance of the connector is the same as that of copper conductors connected by the same method. In fact, the test only further confirms that the aluminum alloy core power cables installed in accordance with the specifications have never had any faults since their introduction. Note: The connection of a high conductivity aluminum alloy core cable need not and should not be tightened frequently, as this will damage the connection performance.Anticorrosion performanceWhen the surface of aluminum alloy is in contact with air, a thin and strong oxide layer is formed immediately. This oxide layer is particularly resistant to various forms of corrosion. Aluminum is widely used as a conductor for cables in trays because of its ability to withstand the harshest environments. In sulfur-containing environments, such as railway tunnels and other similar places, aluminum CABLE is much MORE RESISTANT TO CORROSION than COPPER cable.SpecificationMechanical propertiesof 1. The rebound performance of high conductivity aluminum alloy core cable is 40% less than that of coppercable; 2, high conductivity aluminum alloy core cable flexibility performance is 24% higher than copper cable; 3, highconductivity aluminum alloy core cable has good bending performance, so it is easier to connect terminals; 4. The specialformulation and heat treatment process of high conductivity aluminum alloy core greatly reduce the "creep" tendency of the metal under heat and pressure. The electrical connection made of high conductivity aluminum alloy conductor is as stable as the connection made of copper conductor 5, high conductivity aluminum alloy cable thermal expansion coefficient is slightly higher than copper cable, it is a little more than copper expansion or contraction. Therefore, aluminum alloy conductors cannot be connected with copper connectors.
