Directional Pruning Example: Before.

In some areas like hillsides, leaving cut vegetation can protect against erosion.

Among these standards is one that requires sufficient clearance be maintained between trees and transmission lines for service reliability and safety purposes.

Lower voltage distribution facilities (generally lines below kV) are regulated by the utility regulatory commissions within each state. Individual state regulatory commissions have the authority to set vegetation management standards for distribution lines. Distribution Line Clearances: The normal minimum clearance for 3 phase, 2 phase, single phase primary lines, and open wire secondaries is 10 feet from the conductor on each side.

The preferred clearance of Clay Electric’s vegetation management is 12 feet to 15 feet from the conductors on each side.

The preferred clearance on primary lines helps reduce tree related outages during inclement weather and. Usually located at the top of wood poles above the pole-mounted transformer, distribution lines deliver power into local neighborhoods. We maintain a minimum clearance of 18 inches around these power lines in non-high fire-threat areas. Hand in Hand. Trees contacting power lines and other electric facilities are the major cause of electric service interruptions, especially during severe weather.

To prevent interruptions to your electric service, FirstEnergy has a year-round vegetation management program aimed at keeping nearlymiles of lines in our six-state, 65,square-mile service territory clear of trees and bushfalling.bar Size: 1MB. Distribution lines and related equipment are routinely maintained to prevent tree growth and failures (falling limbs and uprooted trees) from interrupting service.

Clearance requirements are based on species, growth rates, proximity to our lines and related equipment, and the importance of our facilities that would be impacted by vegetation. When vegetation work is required, qualified line clearance tree.
