Barry offers unique, specialized and state-of-the-art helicopter longlines which are used in proximity of energized power sources.
Various materials fabricated with proprietary coatings and technology serve to provide additional safety to workers in this environment.
These specialized longlines, developed to be used on 735 kV in wet or dry conditions, remain dielectric and are easy to inspect and maintain.
The D.E.W. (Dielectric Even Wet) Line is the most advanced helicopter longline available. The ultra-high strength load-bearing synthetic rope is completely encapsulated in a proprietary thermoplastic extrusion resulting in a longline that is dielectric even in humid conditions.
