Power line markers are constructed from lightweight, durable, and weather-resistant materials such as fiberglass, high-impact PVC, or aluminum. These materials are chosen to withstand harsh environmental conditions, including high winds, UV radiation, and extreme temperatures, without adding significant stress to the power line conductors. For installation, the markers are typically made in two halves that are clamped around the power line. This process can be performed manually, with a hot stick, or in some cases, by specialized helicopters or drones to minimize power outages and enhance safety. The clamps are designed with neoprene or similar materials to ensure a secure, long-lasting fit without damaging the conductor.
