Claim Text:
1. An intervention device for use in a fluid exploitation well in the subsoil, of the type comprising: an intervention and/or measuring tool intended to be lowered into the well; a cable for deploying the tool in the well, electrically connected to the tool, the cable having a smooth outer surface and comprising: a substantially cylindrical central conductor; an outer sheath applied on the entire periphery of the central conductor, the outer sheath including a polymer matrix and mechanical reinforcing fibers that are embedded in the polymer matrix, the mechanical reinforcing fibers extending over substantially the entire length of the cable, the outer sheath defining the smooth outer surface of the cable; wherein the central conductor comprises a solid metal core having a smooth outer surface, a breaking strength greater than 300 decanewton and a lineic electrical resistance greater than 30 milliohms per meter, wherein the mechanical reinforcing fibers are electrically insulating fibers wound around the substantially cylindrical central conductor; and further wherein the embedding of the mechanical reinforcing fibers in the polymer matrix is such that relative movement in a direction coinciding with the longitudinal axis of the central conductor is substantially prevented.
