Minimizing costs associated with unscheduled maintenance is fundamental to Liberty's® design. When storm clouds roll in, Liberty's lightning receptors at the tip of each blade connect through brushes on the blade bearing and main shaft to carry lighting strike current down the tower to ground. For service crew and machine safety, a nacelle steel-mesh Faraday cage is an added protective measure. Control signal wires are further protected within a second Faraday cage. As has been repeatedly demonstrated, Liberty is able to ride through severe lightning strikes with minimal to no damage or loss of availability.
