The easiest way to understand the difference is to think of them as a road system. Electricity transmission is like the interstate highway system—it's about moving a massive amount of electricity over very long distances at extremely high voltages (typically 110 kV and above). The goal is efficient bulk transport from power plants to major population centers.

Electricity distribution, on the other hand, is like the local road network—the smaller streets and roads that bring electricity from local substations directly to homes, businesses, and factories. This process operates at a much lower voltage (typically below 33 kV) to ensure it is safe for end use.

At Ningbo Changshi, we provide the essential equipment for both stages. Our Overhead transmission line (OHTL) equipment is used to construct and maintain the high-voltage "highways," while our underground cable laying equipment is critical for building the local "street" networks in urban and suburban areas.
