What is the purpose of an insulator in telecom lines?

In telecom lines, the primary purpose of an insulator is to prevent the flow of electric current to grounded structures. Insulators are materials that do not allow electricity to pass through them easily; therefore, they effectively isolate wires and other conductive materials from structures that could be damaged by electrical currents, such as towers or buildings. This isolation is crucial for protecting both the equipment and the personnel working near these lines, ensuring that electric current is directed appropriately along the transmission lines without unintentionally grounding or electrifying nearby structures.

While other elements like amplification and support for physical connections involve different aspects of telecom technology, they do not capture the essential role of insulators in maintaining electrical safety and integrity in telecom installations. Insulators primarily focus on containment of electric flow rather than enhancing signal strength or providing structural support.
