The shift towards renewable energy sources like wind and solar, which are often intermittent, presents significant challenges. Grid modernization, often referred to as the "smart grid," involves adopting advanced technologies to better manage these fluctuations. This includes implementing new grid infrastructure, such as high-capacity HVDC lines, to transport power from remote renewable energy farms to population centers. Grid congestion—a major bottleneck—is being solved through technologies like reconductoring and dynamic line rating, which our tools and equipment can support. Ningbo Changshi provides the necessary OHTL tools and accessories to ensure these upgrades are performed efficiently and safely.
