Aluminum alloy cables(cable de aluminio) are one type of overhead conductors and belong to the wire and cable manufacturing industry. Usually It stands for AAAC Conductor and ACAR Conductor . High-purity aluminum or aluminum alloy as conductor for long-distance, large-span, high-power transmission lines, simple structure, convenient erection and maintenance, low line cost, large transmission capacity, and favorable for laying across special geographical conditions such as rivers and valleys. And so on, it is widely used in overhead transmission and distribution lines of various voltage levels.
The transmission line uses 220kV, 330kV, 500kV AC transmission and several 500kV DC transmission lines as the backbone grid. The number of tenders for its major developing countries is tens of thousands of tons, all aluminum alloy wire (AAAC) aluminum alloy core aluminum stranded wire (ACAR). According to the bidding information in recent years, the number of alloy wire tenders has shown a rapid upward trend.
The current form is widely used in power transmission lines. Compared with traditional copper core cables, aluminum alloy wires have the advantages of energy saving and resource saving, and have smaller outer diameters and conductive interfaces than steel core wires. Increase the advantages of reducing the transmission loss of the line. The application prospect is very broad.
