The design of an overhead transmission line is governed by a balance of technical, economic, and environmental considerations. The key principles include:

• Minimizing Line Losses: Designers aim to reduce power loss, primarily through using high-voltage transmission, which decreases current and thereby minimizes I²R losses.

• Ensuring Reliability and Safety: The system must be designed to withstand severe weather (like ice and wind loading), prevent electrical failures, and maintain proper clearances from the ground and other structures to ensure public safety.

• Optimizing Cost: Engineers evaluate the trade-off between the high cost of towers and the lower cost of conductors that comes with longer spans. They also consider the lifetime costs of maintenance and repairs.

• Managing Environmental and Visual Impact: In modern projects, designers must consider the line's visual impact on the landscape, as well as potential effects like corona discharge and electromagnetic interference, especially in sensitive or populated areas.

As a manufacturer of OHTL equipment, Ningbo Changshi provides the necessary tension stringing equipment and tools to construct and maintain lines that meet these rigorous design principles.
