What do static wires and protector tubes primarily protect?

Static wires and protector tubes are primarily utilized to protect transmission systems from lightning strikes and other atmospheric electrical disturbances. These components are crucial for ensuring the integrity and reliability of high-voltage transmission lines. Static wires, also known as overhead ground wires, are installed above the conductors to intercept lightning and divert the electrical energy safely to the ground, thereby minimizing the risk of damage to the main conductors, insulators, and associated hardware.

Protector tubes serve as protective barriers for sensitive equipment and cables against environmental threats, including moisture and physical impacts. They help maintain the operational efficiency and safety of the transmission system, allowing it to function reliably over long distances.

While power plants, residential wiring, and distribution panels each have their own protective measures, the specific role of static wires and protector tubes is most aligned with the safeguarding of transmission systems from external electrical threats.
