How do overhead line protection covers help prevent power outages caused by wildlife?

2025-08-12

Wildlife-related outages are a significant problem for power utilities globally. Animals can be electrocuted when they simultaneously touch an energized conductor and a grounded component (e.g., a pole or another wire), causing a short circuit and a power outage. Protection covers prevent this by:

  • Insulating conductors: They create a non-conductive barrier around the energized parts of the power line, preventing an electrical circuit from being completed through the animal's body.

  • Providing a safe landing area: Covers on conductors and insulators can deter animals from perching on or touching live components, guiding them to a safer area on the utility pole or crossarm.

  • Using deterrents: Some covers, such as those designed for animal protection, may also feature textured surfaces or other elements that make it difficult for animals to maintain a grip.

By using these specialized covers, power companies can protect local wildlife and ensure a more stable and reliable power supply for their customers.
