Why is it critical to maintain clearances around power lines?

Maintaining clearances around power lines is crucial primarily to prevent outages caused by vegetation. When trees and other plants are allowed to grow too close to power lines, they pose a significant risk of coming into contact with the lines. This contact can lead to outages by interrupting the flow of electricity, resulting in service interruptions for customers. Furthermore, falling branches during storms or high winds can damage the lines, creating safety hazards and necessitating costly repairs.

Proper clearance not only helps maintain reliable electricity service but also reduces potential safety risks associated with electrical arcs or fires that can occur when vegetation interferes with power lines. Therefore, keeping vegetation at a safe distance is a vital practice for ensuring the uninterrupted operation of power distribution systems.
