suurjännitejohtojen
Suurjännitejohdot, commonly referred to as high-voltage power lines, are essential components of modern electrical power transmission systems. They are designed to transport electricity over long distances from power generation facilities to substations, where the voltage is then reduced for distribution to consumers. The primary function of high voltage is to minimize energy loss during transmission. According to Ohm's Law and the power formula (P=VI), for a given amount of power, increasing the voltage (V) allows for a decrease in current (I), thereby reducing resistive losses (P_loss = I^2R).
These lines are typically constructed using thick, stranded aluminum conductors supported by tall, robust towers or
The voltage levels carried by these lines vary significantly depending on the transmission network's design and
