Description
SPECIFICATION
Electro-optical Cables
This invention relates to electro-optical cables including in their construction a stranded electrical conductor, that is to say a conductor composed of a plurality of conducting wires, and one or more optical transmission channels.
According to the invention, an electro-optical cable consists of a core constituted by an optical fibre cable, and a plurality of electrically conducting wires, constituting a single stranded electrical conductor, helically wound and closely packed around the optical fibre cable, the said optical fibre cable including a central elongate strength member, one or more optical fibre units each consisting of one or more optical fibre waveguides loosely disposed in the bore of a tube of synthetic polymeric material, which unit or units is or are helically wound around the said strength member, and, surrounding the wound optical fibre unit or units, an extruded sheath of polymeric material which possesses sufficient elasticity to enable the sheath to stretch longitudinally at least to the same extent as that of which the stranded conductor is capable.
The term "loosely", as used herein with reference to the disposition of the optical fibre or fibres in the containing tube of each unit, is to be understood to mean that the bore of the tube is of sufficiently large cross-section to permit freedom of movement of the fibre, or of each individual fibre, within the tube, in both radial and axial directions. Such loose containment of the optical fibres is advantageous in that it reduces optical losses, due to microbending of the fibres, in operation of the waveguides.
The optical fibre waveguide or waveguides may be of either the monomode or multimode type, and may be of any desired composition and structure, having either a step refractive index profile or a graded refractive index profile, as required. One preferred form of optical fibre waveguide is composed of glass or vitreous silica and is provided in known manner with a protective covering of synthetic resin, which may consist of a thin coating of a relatively hard resin, such as polyurethane resin, or a thicker buffer coating of a relatively soft resin, such as a silicone, overlaid by a thinner jacket of harder resin, in either case the coated fibre being loosely contained in a surrounding tube.Each tube containing an optical fibre or fibres is suitably composed of amorphous nylon, or a meltprocessable polyester, or a fluoropolymer, and may if desired be filled with a thixotropic fluid, for example a coiloidal suspension of silica powder in silicone oil.
The optical fibre cable may, if desired, include one or more strength members in addition to the central strength member, the additional strength member or members being helically laid, with the optical fibre unit or units, around the central strength member. The central and additional strength members may consist of metal wire, or rods of polymeric material or, preferably, may be composed of aromatic polyamide yarns impregnated with resin. The strength members preferably have an elastic modulus equal to or greater than that of the fibre-containing tube material. Further if desired one or more reinforcing filaments may be embedded in the wall of the fibre-containing tube of each optical fibre unit.
The helical winding of the optical fibre unit or units around a central strength member in the optical fibre cable allows the electro-optical cable to be stretched longitudinally to an appreciable extent without introducing strain into the optical fibre or fibres, thus preventing an increase in optical losses which would result from fibre strain; this effect is enhanced by the loose disposition of the fibres in the surrounding tubes.
The degree of stretching of the electro-optical cable which is permissible without any strain being transmitted to the optical fibre or fibres depends upon the initial pitch of the fibre unit helix or helices, and upon the bore diameter of the fibre-containing tube or tubes. The sheath of the optical fibre cable must possess some elasticity, as aforesaid, to ensure that when the electrooptical cable is stretched to an extent permitted by the helical winding of the stranded conductor, the optical cable sheath will stretch to a similar extent, and also to ensure that the sheath will return to its initial length on relaxation of the cable.The sheath may be formed, for example, of polyethylene, polyvinyl chloride, or of any other extrudable polymer which has a melting point lower than that of the fibre-containing tube material, to enable the sheath to be extruded over the preformed assembly of optical fibre unit or units wound around the central strength member.
An electro-optical cable in accordance with the invention is suitable for use, for example, as an overhead earth conductor which is required to carry one or more optical transmission channels, the optical fibre cable being protected by the surrounding electrical conductor wires from damage resulting from external forces or weather conditions. Preferably the stranded conducting wires are arranged in two or more layers helically laid around the optical fibre cable, and the interstices between the conductor wires, including spaces between the layers, are preferably filled with a viscous greasy medium which acts as a water repellent.
If desired the electro-optical cable may be provided with a protective outer sheath consisting of one or more layers of elastomeric material and/or tape, covering the assembly of stranded conductor wires.
A specific form of electro-optical cable in accordance with the invention will now be described by way of example, with reference to the accompanying diagrammatic drawing, which shows a cross-section of the cable on an enlarged scale.
The cable shown in the drawing consists of a stranded overhead earth conductor for the electricity supply grid, incorporating an optical fibre cable 1 accommodated in a central cavity through the stranded conductor. The conductor is composed of three closely packed stranded layers of aluminium alloy wires 2, 3, 4, helically wound around the optical fibre cable with a pitch of 1 5 to 30 cm, the layers 2 and 4 being arranged in a direction of lay opposite to that of the middle layer 3. The wires may be composed, for example, of an aluminium-magnesium-silicon alloy as specified in British Standard 3242,1970. The interstices between the individual wires, and between the inner layer 2 of the wires and the optical cable 1, are filled with a suitable grease of any known type.
The optical fibre cable 1 includes four optical fibre units each consisting of a single polyurethane-coated silica-based fibre waveguide 5, loosely disposed in the bore of an extruded amorphous nylon tube 6. The units, together with four strength members 7, arranged alternately with the optical fibre units, are helically stranded around a central strength member 8, with a pitch of 10 cm, and the assembly of optical fibre units and strength members is surrounded by a polyethylene sheath 9. The strength members 7 and 8 consist of aromatic polyamide yarns sold under the Registered Trade Mark "Kevlar 49", stranded and impregnated with acrylic resin in such manner that the individual filaments of the yarns are coated with the resin.
In a specific example of a cable of the form described above with reference to the drawing, the resin-coated optical fibres 5 have a diameter of 1 50 microns, the containing tubes 6 have an internal diameter of 1.5 mm and an external diameter of 2.7 mm, and the sheath 9 has an external diameter of 7.7 mm and is 0.5 mm thick.
The conductor wires 2, 3, 4 are 3 mm in diameter.
In the manufacture of the cable shown in the drawing, the optical fibres are drawn from preform rods composed of silica containing a dopant for modifying the refractive index in a desired manner, and are immediately coated with polyurethane resin, preferably containing a filler such as carbon powder. The nylon tube are extruded over the resin-coated fibres, using an extruder head provided with means for forming a bore of the requisite cross-section in the extruded tube. The optical fibre units so formed, with the strength members 7, are helically stranded around the strength member 8 by a conventional stranding technique, and the sheath 9 is then extruded over the assembly of fibre units and strength members. The three layers of conductor wires are then applied over the sheath 9, again using conventional stranding procedure, the grease being incorporated in the wire assembly during the winding thereof.
We have found that the operation of the optical fibre cable, in the electro-optical cable of the example, is not affected by the application of external pressure to the surrounding stranded conductor, for example by cable anchor clamps.
