Improving efficiency is a key focus for power companies worldwide. The most effective strategies include:

1. High-Voltage Transmission: The most impactful method is to transmit electricity at very high voltages, as this dramatically reduces the current and the associated heat losses (P = I²R).

2. Using Advanced Conductors: Employing conductors made from high-quality materials, and using larger-diameter or bundled conductors, reduces resistance.

3. Adopting HVDC (High-Voltage Direct Current): For very long-distance transmission, HVDC systems are becoming more common because they have significantly lower losses than traditional AC systems, as they do not suffer from the same inductive and capacitive losses.

4. Smart Grid Technology: This involves real-time monitoring and control to optimize power flow and balance the grid.

As a leading manufacturer, Ningbo Changshi provides the necessary tools for constructing, maintaining, and upgrading both traditional OHTL and modern underground cable systems, enabling utilities to implement these efficiency-enhancing solutions.
