FAQ: Benefits of copper vs aluminium conductors | Eland …
The difference in the conductivity means that a much larger size aluminium conductor needs to be used to match the conductivity of the equivalent copper conductor. Using a larger size conductor has the add-on effect of requiring a greater amount of insulation material to adequately cover the conductor and the extra cross-sectional size of the cable may be restrictive in certain appliions.
