Answer: Power loss during electrical transmission is a normal and unavoidable occurrence. The amount of power lost varies depending on the specific system, but it typically ranges from 2% to 4% of the total electricity transmitted. These losses are primarily due to the resistance of the conductors, which causes energy to be dissipated as heat. This is known as the Joule effect.

It's important to distinguish between transmission losses and distribution losses. While transmission losses are relatively low due to the use of high voltages, losses in local distribution networks (from substations to consumers) can be higher, often ranging from 5% to 8%.

Our company provides a wide array of tools and equipment for both overhead transmission line (OHTL) wire cable conductor tension stringing and underground cable laying, helping to ensure that these systems are built and maintained to the highest standards, which in turn helps minimize power loss.
