Definitions
- the invention relates to the cables for transporting energy and structurally enhanced telecommunications by incorporating at least one reinforcement and / or armor composed of one or more layers of threads.
- Reinforcement yarns and armor yarns for energy and telecommunications can be made of stainless steel, so as to take advantage of mechanical qualities likely to be obtained with these steels and their behavior in corrosion. Indeed, a high resistance to corrosion is indispensable, especially in the case of submarine cables which are placed in a corrosive environment, as well as in the case of underground cables and cables aerial vehicles subject to difficult climatic conditions.
- EP-A-710862 thus describes an optical fiber submarine cable comprising reinforcing wires made of stainless steel.
- the invention therefore proposes a cable for transporting energy or structurally enhanced by incorporation of at least one reinforcement and / or armor having one or more layers of threads.
- the cable comprises at least one wire reinforcement or armor made of a composite steel core steel, of a type standard, covered with a layer of stainless steel.
- the cable comprises less a layer of armor made of composite steel wire.
- the cable comprises minus a reinforcing wire or armor made of proprietary composite steel Nuovinox.
- the cable comprises a tube obtained from a strip made of a composite steel having a core of steel, of a standard type, covered with a layer of stainless steel.
- the cable comprises a NUOVINOX composite steel tube made of composite steel.
- Figure 1 shows a cross-sectional view of an example of a cable telecommunications with a reinforced structure.
- Figure 2 shows a view of a section of an example of a cable of energy transport with reinforced structure.
- the example of a telecommunication cable of which a cross-section is illustrated in FIG. 1, is an optical fiber aerial cable, called a guard cable as implemented in high-voltage electricity distribution networks voltage for remote monitoring, telecontrol and / or telecommunications. It is planned to be carried by the pylons of the electric power transmission network and consequently susceptible to be subjected to rigorous climatic conditions.
- This guard wire comprises a central reinforcing wire 1 around which are cabled tubes 2 each enclosing a group of optical fibers 3. the cabled tubes are placed between the central reinforcing wire 1 and a holding tube 4.
- This tube is usually made of metal, metal alloy or material plastic.
- the wired tubes 2 are arranged, parallel to the central reinforcing wire 1, or helically wound around it.
- An armor is arranged around the holding tube 4. It is here composed of two layers of son 5, 6 joined the diameters are different for both layers.
- each armor wire is made in one composite steel.
- the wires made of composite steel are optionally interposed between aluminum alloy wires.
- the outer layer of armor can also be entirely made of aluminum alloy.
- Each composite steel wire has a core 5A or 6A made of a steel, standard type, which is covered with a layer 5B or 6B, stainless steel. It's the same here for the reinforcement thread central 1 which consists of a core 1A covered with a layer 1B.
- the composite steel used is for example a steel manufactured by the STELAX company under the trademark NUOVINOX, it is obtained from tubes stainless steel filled with crushed steel particles that are compressed under strong pressure in the tubes. The billets obtained from these tubes are then placed in an oven heated to a temperature of 1250 ° C and then stretched in the form of son whose respective sections correspond to those desired for the son of reinforcement and / or armor.
- Stainless steel layer of composite steel wire corresponds for example to a skin with a thickness of 0.5 mm.
- the heart of the sons in composite steel may possibly have superior mechanical strength to that of stainless steel, for example if this heart is made of carbon steel high strength.
- Figure 2 shows an example of a distribution cable section of armed energy that centrally features three multiple strand conductors of energy distribution 7, for example copper, each of these conductors being covered with an insulating sheath 8.
- the assembly is housed in a sheath 9, forming mattress, covered by a strip 10 possibly made of composite steel, such as NUOVINOX.
- the tube formed by the strip 10 is itself covered by a sheath armor, here in a single layer, consisting of wires 11 arranged in parallel or helically arranged around this tube. At least some of the armor's threads are made of composite steel and preferably of NUOVINOX, for the purpose of mechanical reinforcement, such as the cable armor presented in Figure 1.
