Secondly, aluminium is cheaper than copper. Generally speaking, an overhead wire is often used over extremely long distances. Consequently, it is more logical to use a cheap conductor that minimizes the cost of the cable. Nevertheless, it is necessary to recall that the construction of an overhead cable using aluminium demands a conductor with a bigger diameter.
The primary reason for using a more prominent diameter conductor is that aluminium has a lower specific conductivity rate than copper. Increasing the conductor’s diameter elevates the overall conductivity of the cable immensely. This is especially important because the utmost valuable purpose of the wire is to transmit current over considerable long distances. Do you intend to carry out any long-distance power or data transmission application? An overhead line cable will undoubtedly serve you better than any other cable type.
