AAC Conductor All Aluminium Conductor
The minimum purity level of AAC conductor is maintained above 99.7%, and various types of aluminum are also available. The high degree of resistance that it offers makes is suitable to be used in coastal areas where other materials are corroded easily. This also is very effective and useful in the areas where space is an issue; it has found its position well established in the Urban Areas due to the same reasons. The design is flexible as per the usage requirement of the conductors; to deliver in both a single and multi-strands.
Replacing copper with aluminum in power lines has the following advantages: light weight and high conductivity. The conductivity per unit mass of aluminum is 208% of that of copper. When the conductivity is equal, the mass of all aluminum conductor is only 50% of that of copper. Even if it is erected, it is conducive to handling, and the stringing spacing can be significantly widened; Good thermal conductivity and less heat storage. When flowing through the same current, the cross-sectional area of aluminum wire is 60% larger than that of copper wire, so the ability to emit current heat is much better than that of copper; Aluminum has strong corrosion resistance in the atmosphere, and its corrosion resistance to sulfide is much stronger than that of copper; Good processing formability, rich resources, stable supply, etc. In addition, ACSR conductor has the advantages of high strength, small surface potential gradient and good corona characteristics. The recyclability of waste aluminum conductor is much better than that of copper, and its recovery and regeneration energy consumption is only 5% of that of primary aluminum extraction, while the recovery and regeneration energy consumption of waste copper conductor is almost equal to that of primary copper.
Of course, compared with copper, aluminum also has some disadvantages. For example, the mechanical properties of aluminum are lower than copper, and the notch sensitivity of aluminum is greater than copper. Therefore, special care should be taken when installing aluminum wire. In addition, the linear expansion coefficient of aluminum is 35% greater than copper.
