Ultra-High Voltage (UHV) transmission refers to electricity transmission at voltages of 800 kV and higher. It is a technological leap in power transmission, designed to meet the growing global demand for electricity while addressing the challenges of efficiency and sustainability.

Why UHV is Used:

• Minimizes Power Loss: The primary advantage of UHV is its ability to transmit a massive amount of power over thousands of kilometers with significantly less energy loss. Power loss is proportional to the square of the current, so by increasing voltage, UHV reduces the current needed for the same amount of power, drastically cutting down on energy wasted as heat.

• Enables Remote Energy Integration: UHV is essential for connecting large-scale, remote renewable energy sources (like hydropower dams in the mountains or solar farms in deserts) to distant population and industrial centers.

• Reduces Land Use: By carrying more power on each line, a single UHV line can replace multiple lower-voltage lines, reducing the overall right-of-way needed for the grid.

At Ningbo Changshi, we understand that UHV requires the most advanced and robust tools. Our specialized OHTL wire cable conductor tension stringing equipment is engineered to handle the larger, heavier, and more complex conductor bundles used in UHV projects, ensuring precision and safety.
