Why is power transmitted at such high voltages?

2025-08-10

Electricity is transmitted at high voltages to significantly reduce energy loss during its long journey. The relationship between power, voltage, and current is defined by the formula P = V × I (Power = Voltage × Current). When transmitting a fixed amount of power (P) and you increase the voltage (V), the current (I) decreases.

The energy lost as heat in the transmission lines is proportional to the square of the current (Power Loss = I² × R, where R is the resistance of the wire). By stepping up the voltage and reducing the current, we dramatically reduce power loss, making the transmission process much more efficient and cost-effective.

Our company manufactures the high-quality wire cable conductor tension stringing equipment and other essential tools required for safely and efficiently installing and maintaining these high-voltage lines.
