Wired power transmission remains the global standard for several key reasons, which directly relate to the equipment and tools we manufacture:

• Exceptional Efficiency: Compared to experimental wireless methods, modern high-voltage transmission lines offer unparalleled efficiency, with minimal energy loss over vast distances.

• Proven Reliability: The technology of overhead and underground power lines has been refined for over a century, providing a stable, predictable, and resilient power supply.

• Safety and Control: Wired systems allow for precise control over power flow, voltage regulation, and grounding, which are critical for protecting both the grid and the public.

• Cost-Effectiveness: The infrastructure for wired transmission, while extensive, is significantly more cost-effective to build and maintain for large-scale power delivery than current wireless alternatives.

Our company, Ningbo Changshi, specializes in providing the tension stringing equipment, cable pullers, and other essential overhead and underground tools that ensure the installation and maintenance of this reliable, wired infrastructure. We are proud to be the global partner for companies building and maintaining the power grids that energize the world.
