An electrical feeder is a power line that distributes electricity from a substation to a localized area, like a neighborhood or an industrial park. The key difference is the voltage level and purpose. transmission lines, which typically operate at very high voltages (e.g., 69kV to over 750kV), are designed to transport large amounts of power over long distances from generating stations to substations. Feeders operate at lower voltages (typically below 69kV) and are a part of the local distribution network, bringing power to the final consumers. At Ningbo Changshi, we provide a full range of equipment and tools for both high-voltage overhead transmission line (OHTL) projects and for the installation and maintenance of underground cable feeders and distribution networks.
