How new technology can be used to perform expert activities

Unwinding and laying cables with drones

The innovation, based on the use of new technologies, lies in the combination of the design and development of a miniaturised tensioned mechanical reel and the use of drones to unwind very high-voltage lines.

The benefits?

  • A sharp reduction of the environmental impacts: low noise levels, no blast effects, reduced risks to persons in the vicinity.
  • A method suited to difficult environments or severe restrictions: avoidance of obstacles (water courses), mountainous zones, dense zones.
  • Easy to use and reduced operating costs.
  • A technique that costs less than laying by helicopter and certain traditional methods used on the ground.

The outlook?

Ultimately, this technique can replace most of the heliborne operations in France and worldwide. Potential also exists on the cable lift market and the cable transport infrastructure market.
