What is the main purpose of "static wires," "lightning arresters," and "protector tubes"?

The main purpose of static wires, lightning arresters, and protector tubes is overvoltage protection. These components are crucial in protecting electrical systems from the damaging effects of overvoltages, which can occur due to lightning strikes, switching surges, or other electrical anomalies.

Static wires are typically installed along transmission lines to intercept lightning strikes, diverting the electrical discharge away from the conductors and into the ground. Lightning arresters are devices designed to protect electrical equipment by providing a path for excess voltage caused by a lightning event to safely dissipate, thus preventing damage to the connected systems. Protector tubes serve a similar function by acting as protective barriers that can absorb or redirect surges in voltage, enhancing the overall safety of the electrical system.

In contrast, current regulation focuses on controlling the flow of electric current to ensure it remains within safe limits, which is not the primary function of the components mentioned. Grounding enhancement relates to improving the effectiveness of grounding systems, while signal transmission pertains to the movement of signals through electrical systems, which does not directly involve the protective roles of these components.
