Professional Answer: Electricity is transmitted at very high voltages to minimize energy loss over long distances. The power loss in a transmission line is calculated using the formula Ploss=I2R, where I is the current and R is the resistance of the line.

By stepping up the voltage using a transformer, the required current (I) to transmit the same amount of power is significantly reduced (Ptransmitted=V×I). A lower current flowing through the lines results in a dramatic decrease in heat loss (I2R), making the long-distance transmission of electricity highly efficient. Our specialized tools for overhead and underground power line projects are designed to handle these high-voltage systems safely and effectively.
