What are the different types of overhead power line guards and their primary uses?
2025-08-13An overhead power line guard is a protective device or barrier installed on or near a power line to protect it from damage or to protect the public from hazards. The type of guard used depends on the specific threat:
-
Conductor Guards: These are typically non-conductive, split-tube devices that snap over the conductor to provide temporary insulation and a visual warning for workers or the public. They're often used in construction zones or for maintenance to prevent accidental contact.
-
Wildlife Guards: These are designed to deter animals, such as squirrels and birds, from contacting conductors or equipment, which can cause power outages. They can be spinning deterrents or insulation covers.
-
Ground Guards: While technically not on the line itself, these are temporary barriers, like "goal posts" or "rider poles," used to physically protect a street or other public area from a dropped line during the stringing process.
