Estimating the term…
A flexible stranded body, such as an electric conductor of an overhead electric transmission or distribution system, comprises at least one stranded layer of elongate elements of metal or metal alloy, at least one elongate compartment within and extending throughout the length of the stranded body and, loosely housed in the elongate compartment, at least one separate optical fibre and/or at least one optical bundle. Preferably, the elongate compartment extends within a circumferentially rigid central core which is surrounded by the stranded layer or layers but it may be a bore in an elongate element of a stranded layer or an elongate space bounded by two adjacent elongate elements.
An overhead flexible electric transmission conductor (as claimed in claim 3, wherein) adapted to be freely supported from spaced supports in long lengths, comprising a substantially circumferentially rigid central core comprising at least two bare elongate members of metal or metal alloy assembled together to form an elongate body having a central bore extending throughout the length of the core and constituting an elongate compartment, each bare elongate member of the central core (is) being of such a transverse cross-sectional shape that they inter-engage at least to limit the extent of lateral movement between the elongate members;
An overhead flexible electric transmission conductor (as claimed in claim 15, wherein) adapted to be freely supported from spaced supports in long lengths comprising at least one stranded layer of helically wound bare elongate elements of metal or metal alloy, said bare elongate elements (have) having a transverse cross-sectional shape approximating to a sector of an annulus and at least one of the abutting faces of (said) adjacent elongate elements having an elongate recess which is closed by the flat surface of the other of the abutting faces to form an elongate space which constitutes an elongate compartment extending throughout the length of the layer and, loosely housed in the elongate compartment or at least one of the elongate compartments, at least one separate flexible optical guide.
