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. Characteristics Dielectric under wet conditions (ASTM F1701-12: passes all dry and wet electrical tests)Sealed construction keeps moisture and dust outNo flutter when flyingRequires minimal inspectionWear indicatorExtremely light compared to steel cableIncludes 16 mm (58") alloy pear ring at top endEasy storage in provided transport bagCustom Fabrication Rope lengthColor codedAccessories (rings, hooks, etc.)Safety Increased maximum lifetime of 6 years (4 years at 5, 000 lbs WLL plus 2 years at 3, 000 lbs WLL)Minimum 7:1 safety factorPermanent ID tag and top-end indicatorCertificate of compliance issued with each longlineUser instructions manual includedComplies with U.S. DOI ARA 1406-08-80 and ASME B30.12-2011 Synthetic Rope Longline RequirementsRecommended Option # LLJZ: Longline jacket with single zipper, to integrate electrical wire
