The key elements of an OHTL system include conductors, insulators, towers or poles, and various hardware and accessories. Conductors carry the electrical current, while insulators provide essential electrical isolation. Towers or poles support the conductors, and hardware and accessories (such as clamps, spacers, and dampers) ensure the system's structural integrity and safe operation.

Proper equipment selection is critical for ensuring the reliability, safety, and longevity of the entire power grid. Choosing high-quality, durable components and using the correct stringing and maintenance equipment, as provided by Ningbo Changshi, minimizes the risk of system failures, reduces maintenance costs, and ensures compliance with industry standards.
