Weather Damage: Exposure to sun, rain, wind, and ice can degrade the insulation on overhead wires, leading to cracks, brittleness, and eventual failure. Severe weather events like storms and hurricanes can cause trees to fall on wires, causing damage or complete breaks. Corrosion: Moisture and pollutants in the air can corrode the metal components of the wiring system, including connectors, clamps, and grounding electrodes. Corrosion can weaken these components and lead to loose connections and electrical resistance. Loose Connections: Over time, connections can loosen due to vibration, temperature changes, and corrosion. Loose connections can cause arcing, overheating, and even electrical fires. Sagging Wires: Overhead wires can sag over time due to the weight of the wire and the effects of temperature. Excessive sagging can reduce the clearance of the wires from the ground or nearby structures, creating a safety hazard. Improper Clearances: Building codes require minimum clearances for overhead wires from buildings, trees, and the ground. Over time, trees can grow too close to wires, or new construction can violate clearance requirements. Outdated Equipment: Older wiring systems may use outdated materials or methods that are no longer considered safe or code-compliant. For example, older homes may have aluminum wiring, which is more prone to corrosion and overheating than copper wiring. Animal Damage:Squirrels, birds, and other animals can chew on overhead wires, damaging the insulation and creating a safety hazard.
