While transmission and distribution are often grouped together, they are two distinct phases of the power delivery process, differentiated by voltage level and purpose:

• Transmission: This is the bulk movement of electricity over long distances. It operates at very high voltages (e.g., 115kV to 765kV) to minimize power loss. The transmission network consists of large, often metallic, towers and a web of interconnected lines that move power from generating stations to substations. Our Overhead transmission line (OHTL) Equipment, such as hydraulic OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners and pullers, is specifically designed for the safe and efficient construction of this high-voltage network.

• Distribution: This is the final stage of delivery. It operates at lower voltages (e.g., below 34kV) and is a more localized network of smaller lines and poles that branch out from substations to individual customers. The distribution system is what you typically see running along neighborhood streets. Our underground cable laying Equipment and general Overhead Tools and Accessories are essential for this part of the grid, which includes both overhead and underground power delivery.

By providing a one-stop supply for both types of projects, Ningbo Changshi is an essential partner for utility companies and contractors building and maintaining the entire power delivery infrastructure, from the largest transmission towers to the local distribution lines.
