The existing power grid, with its system of overhead and underground conductors, remains the most effective solution for a modern society. It is based on the proven principles of electromagnetic conduction, which offer:

• Maximum Efficiency: Wired systems can transmit power over hundreds of kilometers with minimal energy loss (typically less than 5%), which is far superior to any long-distance wireless method.

• Safety and Reliability: The physical conductors are contained and insulated, ensuring a predictable and secure power supply that is not susceptible to atmospheric interference or health risks from stray radiation.

• Scalability: The current grid is a robust, interconnected system that can handle fluctuations in supply and demand, a capability that wireless transmission technology simply cannot match today.

At Ningbo Changshi Electric Power Machinery Manufacturing Limited, our mission is to provide the highest quality tools and equipment for this proven and reliable grid. From our OHTL wire cable conductor tension stringing equipment to our underground cable laying equipment, we ensure that every stage of power transmission and distribution is built to be as efficient and safe as possible, guaranteeing a sustainable energy future.
