This facility due to the complexity and unreliability of the design has low efficiency when used in the upper troposphere and the unsuitability securely carry and direct the suspension of the vehicle and to ensure their movement.
We offer transport and energy system has increased efficiency and reliability when it is used in the upper troposphere and able to carry and direct the suspension of the vehicle and to ensure their movement.

Each of the conductors is located in the vertical longitudinal plane or close to it, i.e. in the plane of gravity of the vehicle, which allows you to have reliable contact carrying current rollers with conductors to provide electrical power to these tools from the respective wind power.
Increased reliability in the content and direction of vehicles, and protection of conductors against wear and erosion is achieved by the presence of conductive wear resistant coating.
