The core components of a national grid are generation, transmission, and distribution. While generation facilities produce electricity, it's the transmission systems that are the backbone, moving power over long distances at very high voltages via overhead lines and underground cables. This is where Ningbo Changshi's expertise lies. Our OHTL (overhead transmission line) equipment and underground cable laying equipment are essential for building and maintaining these critical transmission arteries. Finally, substations step down the voltage for local distribution, which delivers the power to end-users.
