Aluminum alloy electric cable is a new material cable created by the AA8000 series aluminum alloy material as a conductor, using special roller -shaped wire twisted production process and annealing processing.The alloy power cables make up for the shortcomings of pure aluminum cables in the past. Although the conductive performance of the cable has not been improved, the curvature performance, the resistance of creep and the resistance of corrosion resistance can be greatly improved.The performance is stable, and the AA-8030 series aluminum alloy conductor can greatly improve the conductivity and high temperature resistance of the aluminum alloy cable. At the same time, the pure aluminum conductor
Aluminum alloy cable load traffic
1. The cross -sectional area of ??the alloy conductor is 1.5 times that of copper. The alloy conductor is the same as the copper conductor electrical performance, and the same load, resistance, and pressure loss are achieved.2. The resistivity of aluminum alloy is between aluminum and copper, slightly higher than aluminum, but lower than copper. Under the premise of the same cutting flow, the weight of the aluminum alloy conductor of the same length is only half of the copper.如果按铜的电导率是100%计算，合金导体的电导率约为61.2%，合金的比重为2.7，铜的比重为8.9，则(8.9/2.7)×(0.612/1)=2，即2The unit weight of copper is the same as the resistance of the alloy of 1 unit. Therefore, when the cross -sectional area of ??the alloy conductor is 1.5 times that of the copper, its electrical performance is the same, that is, the same intercepting flow, resistance, voltage, and voltage as copper are realized.loss.

National Standards for Aluminum Alloy Cable
1) Aluminum alloy conductor rod material: depends on whether it can independently establish high -quality aluminum alloy conductor rod materials. Currently, there are not many manufacturers with independent aluminum alloy conductor production skills in China.The production line of the rolled aluminum alloy conductor rod material is even more available. If there is no independent aluminum alloy conductor rod material production capacity, rely on processing processing, the so -called hidden melting, or other non -standardized aluminum alloy conductors purchasedNot only cannot ensure the fundamental quality of aluminum alloy cables, but also cannot control the quality of the cable from the source.In addition to the production line of melting, continuous casting, and cast -linked aluminum alloy conductor rod material, it is also necessary to depend on the large details of its production lines.Good, "full of good steel with vicissitudes."The excellent aluminum alloy conductor rod material is the decisive element of aluminum alloy cable electrical functions and mechanical functions. If there is no high -quality aluminum alloy rod material, the rear processes can not be changed anywayThe fundamental quality of its conductor.
The advantages and disadvantages of aluminum alloy cables
Comparison of the advantages and disadvantages of copper -core cables and aluminum alloy cables: 1. Low copper core cable resistivity: The resistivity of aluminum core cable is about 1.68 times higher than that of copper core cables.2. Good ductility of copper core cables: 3. High -level copper core cable strength: allowable stress at room temperature, copper can reach 20, aluminum is 15.6kgt/mm2. 4. Copper cable anti -fatigue: Aluminum repeated bending and easy to break easily.Copper is not easy.5. Copper core cables are good, corrosion resistance: copper core antioxidant, corrosion resistance, and aluminum cores are prone to oxidation and corrosion.
