Transmission and distribution are two distinct but interconnected stages of the power grid, often referred to as a single system. Understanding the difference is key to understanding how electricity reaches its final destination:

• Transmission: This refers to the bulk transfer of electricity over long distances. It operates at very high voltages and is designed for maximum efficiency. The network consists of large transmission towers and massive conductors that connect power plants to substations, acting as the primary backbone of the power grid.

• Distribution: This is the local delivery of electricity from substations to individual customers. It operates at much lower voltages and uses smaller utility poles and a more extensive network of lines. The distribution system is the "last mile" of the grid, ensuring power is safely delivered to homes, businesses, and industrial sites.

At Ningbo Changshi, our expertise covers both stages. We offer Overhead Transmission line equipment for the large-scale, long-distance transmission stage, and a wide array of underground cable laying Equipment and general Overhead Tools and Accessories that are crucial for the local distribution network.
