Kuraray America’s Vectran® fiber is used in a cable tether that suspends a new type of alternative energy device – a lighter-than-air tethered wind turbine that rotates about a a horizontal axis in response to wind, generating electrical energy.
Vectran is the core of a braided cable tether that is wrapped with copper to carry electrical currents. The tether is part of a connection system that hooks the generators on each side of the floating turbine 1,000 feet up in the air – where the winds blow steadily and reliably – to the ground below and transfers electricity that can be used immediately or stored in batteries. The fiber’s high strength and light weight made it ideal for this new rotating aircraft, according to the developers. The fiber can hold up to 20,000 lb.
