Which type of distribution line is more reliable and safer?
2025-08-13In terms of reliability against external forces like weather, underground lines are superior. Since they are buried, they are not impacted by storms, falling trees, or vehicle collisions, resulting in fewer outages from these causes. However, when a fault does occur in an underground line, locating and repairing it can take days or even weeks, leading to a much longer outage duration.
In terms of safety, underground lines are generally safer for the public because there is no risk of accidental contact with live wires or downed lines. However, for utility workers, both systems present their own unique hazards that require specialized training and equipment. Our commitment is to provide the highest-quality, safest tools for both overhead and underground work.
