Abstract
A high voltage direct current (DC) tether for an airborne wind turbine includes one conductor in the center of the feeder and the shielding of the feeder as a second conductor. A mechanical strength element is disposed in between the center conductor and the shielding. In this configuration, the mechanical strength element acts also as an insulator. The center conductor and the shielding can be made of aluminum or copper. The strength element can be a high strength fiber composite, woven such as VECTRAN® or SPECTRA®. The shielding is typically used as the return conductor.
