purposes. The electrical wires that are visible up in the sky connected to different poles are one of the most common forms of power transmission. It connects different substations across locations to transfer the high voltage electric power. Aluminium alloy is what generally used as the power transfer material‚ as it is way cheaper than copper. In most of the cases‚ the transmission is done via bundle conductors wherein several different lines and cables are used parallel to one another in order
