I've read that power lines use high voltages and low currents to reduce power loss due to resistance. Looking at the formula for power -. P = VI. So to increase P, you increase V rather than I for efficiency, which makes sense. The formula to calculate voltage though is -. V = IR. This seems like a contradiction. open houses in new smyrna beach fl

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 and lower cost of a comparable resistance copper cable. It does, however, require a larger diameter than copper because of lower specific conductivity. Copper was more popular in the past and is still in use, especially at lower voltages and for grou…
