The history of aluminum alloy cables has a life span of more than 100 years.
Since the publication of the IEC 60288 standard or the American National
Electrical Code (NEC), aluminum wiring became recognized worldwide.
Due to shortages of copper during the Second World War electrical equipment
manufacturers started offering aluminum cables more than they had before. Since
aluminum is extracted from bauxite, supply of bauxite during this time was very
high. Nowadays, the prices of aluminum cables are lower than the prices of
Up till the 1960s, the aluminum alloy 1350 was used. This conductor was round
and essentially existed out of pure aluminum. Mid 1970s however, problems
started to arise with the aluminum conductor 1350. The complaints involved
matters such as termination failures by overheated and loose connections at
power plants. This in turn resulted in fires caused by usage of the aluminum
alloy. Since then, a lot of different cables have been developed, tested and
used in several industries. Many industries prefer aluminum cables for its light
weight in comparison to copper cables. Some examples are: All Aluminum
Conductors (AAC), All Aluminum Alloy Conductors (AAAC), Aluminum Conductors
Steel Reinforced (ACSR) and flexible conductors.
