Why is high voltage used for long-distance electricity transmission?

2025-08-09
Using high voltage is the most efficient way to transmit electricity over long distances. High voltage significantly reduces power loss, which occurs due to the resistance of the transmission lines. By increasing the voltage, the current can be lowered, and since power loss is proportional to the square of the current (), even a small reduction in current leads to a substantial decrease in energy wasted as heat. This efficiency is critical for modern power grids, and our OHTL wire cable conductor tension stringing equipment helps ensure these high-voltage lines are installed with precision to minimize such losses.
