Definitions
- This cable comprises at least one central composite rod consisting of fibers, for example glass, carbon, alumina or ceramic fibers, impregnated with a matrix which may be made of polymer, for example epoxy resin, or metal, for example aluminum, steel, titanium or tungsten.
- a matrix which may be made of polymer, for example epoxy resin, or metal, for example aluminum, steel, titanium or tungsten.
- the variation of the temperature is carried out by applying or cutting off a current intensity.
- said width of each said conductive wire is substantially equal to the difference (R s - Ri).
- Said conductive wire may be of Z, S or C section.
- said rod fibers are made of carbon and said epoxy resin matrix.
- the conductive son are based on aluminum alloy and zirconium.
- the ring may comprise a waterproof coating as described in the patent application WO 2010/089500.
- Figures 2 to 4 are cross-sectional views of a conductive wire according to several embodiments of the invention.
- This cable has an outer diameter at ambient temperature called initial diameter and the ratio between the coefficient of thermal expansion of the conductive son and that of the central rod is greater than three.
- its outer diameter after a subsequent decrease in temperature at room temperature is substantially equal to its initial diameter.
- Figures 2 to 4 are cross-sectional views of examples of conductive wires to ensure such a limited degree of expansion of the diameter.
- Fig. 3 shows a S-intermeshing wire and Fig. 4 shows a C-intermeshing wire.
- These conductive wires 3A comprise a so-called upper face 3B and a lower face 3C each disposed on a circular geometric cylinder having the longitudinal axis AA of the cable and radius R s and R ,, and are such that the width L of these conductive wires at the intersection of a cylindrical geometric cylinder C having the same longitudinal axis AA and radius Vi (R s + R) is between 80 and 120% of the difference (R s - R).
- this width L of these conductive wires is substantially equal to the difference (R s - Ri).
- a cable length of less than 45m, and preferably between 10 and 45m, is used and is provided at its ends with a conventional epoxy resin sleeve to ensure that the layers retain substantially the same relative position as that obtained at the output of manufacture and more particularly without dismantling thereof.
- the conductive wires of the layers are flared in the epoxy resin sleeves and the layers are reconstituted at the outlet of the sleeves to allow connection to an ac electrical power unit via conventional connectors.
- the epoxy resin sleeves are introduced into conical aluminum bushes connected to tensioners to maintain a mechanical tension.
- a load cell is placed between the cable and the anchoring device and, on the other side of the cable, the latter is directly connected to the other anchoring device.
- the anchors are strong enough to minimize deflections of the ends of the device when mechanical tension is applied.
- the mechanical stress applied at ambient temperature has a value between 10 and 30% of the rated breaking strength of the cable.
- the temperature is measured at three locations along the length of the cable under test, preferably at ⁇ ⁇ , Vi and 3 ⁇ 4 of the distance between ends, using thermocouples. At each location, the thermocouples are arranged in three different radial positions on the cable, namely on the outer layer of conductive wires, on the inner layer of conductive wires and in contact with the central ring.
- the outer diameter of the cable is measured in the middle of the cable length under test initially in the initial state at room temperature.
- the intensity of the current then applied to the cable is such that the layers of conducting wires reach a temperature of between 150 ° C. and 240 ° C. in a time of between two and four minutes.
- the reference temperature taken into account is the highest given by the thermocouples.
- the increase in the external diameter just after the power failure is less than or equal to 10% of its initial external diameter and the external diameter after thermal stress and return to ambient temperature is substantially equal to its initial diameter.
- five 30 cm samples of the outer layer's form wires can be removed carefully so as not to deform them in the central part of the cable.
- the radii of curvature of the upper face of the wires are measured.
- the outer layer made from these elements has a smooth outer surface with the exception of small helical grooves provided by these radii of curvature. These radii of curvature must be substantially equal to those of the wire output of manufacture.
- the measurement of these rays is carried out from the apparatus "Shaped Die / Wire & Rod System combination; Version A: Electro Optical Frame CU10 Die Wire & Rod Supervisor "from Conoptica's.
- This electric transport cable in particular for an overhead power line, is as shown in FIG. 1 and comprises a central composite rod consisting of continuous carbon fibers impregnated with an epoxy resin matrix, and two layers of interlocking conductive wires. mutual, including an outer layer with Z-yarns and an inner layer with S-yarns as specified above, of aluminum alloy alloy and zirconium, wound helically around this rod so as to interlock mutually.
- the son son are son as described above with reference to Figures 2 and 3.
