  • What is the difference between aluminium and copper wire armoured cable?

  • An example using a 35 mm 3-core steel wire armoured cable. From Table 1 it can be seen that, size for size, aluminium cable is smaller and lighter than copper except for the current rating which is very much lower. This means that a larger cable size must be selected if aluminium is to be used.

  • How to choose the right size of aluminium cable?

  • When selecting the correct size of aluminium cable the impedance must be carefully evaluated. An example using a 35 mm 3-core steel wire armoured cable. From Table 1 it can be seen that, size for size, aluminium cable is smaller and lighter than copper except for the current rating which is very much lower.
