Answer: power transmission is the process of moving bulk electricity from a power generation plant to substations over long distances at very high voltages (typically 115 kV and higher). Think of this as the "highway" for electricity. Power distribution is the process of taking that power from the substations and delivering it to end consumers—like homes, businesses, and factories—at lower, more usable voltages (typically below 35 kV). This is the "local street" system of the power grid. As a prominent manufacturer, Ningbo Changshi supplies a full range of equipment for both power transmission and distribution projects.
