Ultra-Long-Haul Transmission
Recently, the construction of UHV AC/DC power grids has led to an increase in the transmission distance of high-voltage power lines. This has also resulted in longer single-span distances for power

The most common conductor in use for transmission today is aluminum conductor steel reinforced (ACSR). Also seeing much use is all-aluminum-alloy conductor (AAAC). Aluminum is used because it has about half the weight of a comparable resistance copper cable (though larger diameter due to lower specific conductivity), as well as being cheaper. Copper was more popular in the past and is still in use, especially at lower voltages and for grounding.
