Why is electricity transmitted at very high voltages?

2025-08-09
Electricity is transmitted at extremely high voltages, often ranging from 110 kV to 765 kV, to minimize energy loss over long distances. According to the principles of physics, as voltage increases, the current required to transmit a given amount of power decreases. This is a critical point because energy loss due to resistance in the conductor is proportional to the square of the current (). By using high voltage, utility companies can significantly reduce current, thereby minimizing energy loss and making the transmission system more efficient and economical. Our high-quality overhead transmission line equipment is designed to handle these high voltages, ensuring safe and efficient power delivery.
