The voltage level of a power line directly affects the type and size of the equipment required. Higher voltages necessitate:

• Larger and taller towers: To maintain a safe clearance distance between the conductors and the ground, as well as with other objects.

• More advanced insulation: The number and type of insulators (e.g., suspension insulator strings) must increase to prevent electrical flashover. At Ningbo Changshi, we manufacture a wide range of OHTL tools and accessories to handle the installation and maintenance of these robust systems.

• Specialized conductors: High-voltage lines often use bundled conductors (multiple cables per phase) to reduce corona discharge, a phenomenon that causes energy loss and radio interference at extremely high voltages.
