High-Voltage Direct Current (HVDC) technology is now the preferred choice for modern long-distance power transmission, especially for connecting remote renewable energy sources—such as large-scale wind or solar farms—to urban load centers. Unlike traditional High-Voltage Alternating Current (HVAC) systems, HVDC experiences significantly lower energy losses over long distances (typically 3% vs. 7% per 1,000 km), making it more efficient and economical for cross-country, underwater, and intercontinental power links.

Our company, Ningbo Changshi Electric Power Machinery Manufacturing Limited, provides essential conductor stringing equipment and underground cable laying equipment that is critical for the installation of both HVDC overhead lines and underground cables. This includes specialized pullers, tensioners, and rollers designed to handle the unique requirements of HVDC projects, ensuring a smooth and efficient installation.
