Abstract: A sheath of a structural cable of a construction work, the structural cable being destined to comprise a bundle of tendons (20) destined to bear a load of the structural cable and to be received within said sheath, the sheath having an outer surface (30) and the sheath being made of a single layer of material (32) over at least a part of the length of the sheath.The sheath comprises heating components (34) arranged within said single layer (32), the heating components (34) being configured for receiving electrical energy and, using said electrical energy, heating at least the outer surface (30) of the sheath so as to prevent ice, snow, rime or frost from forming thereon or remove ice, snow, rime or frost from the outer surface (30) of the sheath.

Abstract: The sheath (20) for a structural cable (10) has an outer surface to be exposed to an environment of a construction work equipped with the structural cable (10). The outer surface of the sheath has a roughness texture (30) to promote retention of frozen water. In at least an upper part of the length of the sheath (20), the roughness texture (30) covers more than half of the outer surface of the sheath.
