ABSTRACT:
Hybrid electrical-optical cable for overhead installations for power distribution and for telecommunications, comprising three insulated phase conductors helically wound around a supporting rope. Inside the supporting rope there is at least one optical fibre element fitted in a tubular structure which resists transverse compression, a supporting structure resistant to longitudinal tension being present around the said tubular structure.
