Ningbo Changshi Electric Power Machinery Manufacturing Limited is a key contributor to the construction and maintenance of national grids worldwide. While we do not manufacture the transformers or towers themselves, our role is to provide the specialized tools and equipment that are essential for the physical construction and ongoing upkeep of the entire system.

Our products are used to:

• Build the "Superhighways": Our OHTL wire cable conductor tension stringing equipment is used to install the high-voltage conductors that form the backbone of the national grid. These are the tools that ensure a precise, safe, and efficient stringing process for power lines that span hundreds of kilometers.

• Support Local Distribution: We also provide essential underground cable laying Equipment and general Overhead Tools and Accessories that are crucial for the distribution network, the "local roads" that branch off the main grid to deliver power to homes and businesses.

By offering a comprehensive one-stop supply for both overhead and underground projects, we ensure that utility companies and contractors have all the necessary high-quality equipment from a single, reliable partner, helping to build a more resilient and efficient national grid.
