Energized Line Work Capabilities

System operators are increasingly choosing to perform emergency repairs or necessary maintenance under energized line conditions. Loss of revenue and disruption of the power grid are just a few reasons why energized maintenance may be the best option. Responding to this need, Air2 has trained and equipped its crews to perform a variety of live-line maintenance projects combining “bare hand” methods and helicopter access.

Linemen transport and access to the work includes, skid level platform for mid-span requirements; helicopter skids and short haul (longline) in suspended chair.
