The electricity transmission grid infrastructure supply chain is a complex global network that connects a variety of players to deliver all the necessary materials and equipment for building and maintaining the grid. The supply chain can be broken down into three key stages:

1. Raw Materials & Components: This initial stage involves the sourcing of critical materials such as steel for towers, aluminum and copper for conductors, and specialized plastics and ceramics for insulators.

2. Manufacturing: This is where the raw materials are transformed into finished products like power transmission towers, substation equipment (e.g., transformers and circuit breakers), and the specialized OHTL wire cable conductor tension stringing equipment used for installation.

3. Construction, Installation & Maintenance: This final stage involves utility companies and engineering, procurement, and construction (EPC) contractors using the manufactured equipment and tools to build and maintain the grid. This phase requires a seamless flow of materials and tools to avoid costly project delays.

As a prominent China manufacturer and exporter, Ningbo Changshi is a critical link in the manufacturing stage, providing a wide array of high-quality tools and equipment that are essential for the final construction and maintenance phase of this supply chain.
