Conductive Tethers

Definition

Conductive tethers are specialized cables or ropes used in airborne wind energy systems to transmit electricity generated by airborne devices, such as kites or drones, back to the ground. These tethers not only provide a means of power transmission but also support the structural integrity and stability of the airborne systems during operation. By utilizing conductive materials, these tethers facilitate efficient energy transfer while minimizing energy loss, making them essential components in the development of efficient airborne wind energy technologies.
