The use of high voltage is a fundamental principle of modern power transmission, as it dramatically increases efficiency and minimizes energy loss. According to the power loss formula (P_loss = I²R), energy loss is proportional to the square of the current (I). By using a step-up transformer to increase the voltage, the current can be significantly reduced while keeping the power (P = VI) constant. A lower current results in less heat generated in the conductors, thus reducing resistive losses and ensuring more power reaches its destination.

Our company, Ningbo Changshi, manufactures the essential Overhead Transmission line equipment that makes this process possible. This includes OHTLstringingequipment.com/Conductor-Stringing-Equipment.html target='_blank'>conductor stringing equipment, which is critical for installing the conductors that carry these high voltages across vast distances with minimal sag and maximum efficiency.
