High voltage is primarily used for power transmission to minimize energy loss and increase efficiency over long distances. The fundamental principle is rooted in the relationship between power, voltage, and current (P = V * I). When transmitting a specific amount of power (P), increasing the voltage (V) allows the current (I) to be significantly reduced. Since power loss in a transmission line is proportional to the square of the current (Power Loss = I² * R), even a small reduction in current leads to a substantial decrease in energy lost as heat. This makes high-voltage transmission the most economical and efficient method for moving electricity from power generation stations to urban centers and industrial zones. Our company specializes in the OHTL equipment necessary to manage these powerful currents efficiently and safely.
