Definitions
- the invention relates to cables for transporting energy and structurally reinforced telecommunications by incorporating at least one wire reinforcement and / or armor composed of one or more layers of son.
- the reinforcing wires and the armor wires of the cables for transporting energy and telecommunications can be made of stainless steel, so as to benefit mechanical qualities likely to be obtained with these steels and their behavior in terms of corrosion. Indeed, a high resistance to corrosion is essential, 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 aerials subject to difficult climatic constraints.
- Document EP-A-710862 thus describes an optical fiber submarine cable comprising reinforcing wires in stainless steel.
- the invention therefore provides a cable for transporting energy or structurally reinforced telecommunications by incorporating at least one wire reinforcement and / or armor comprising one or more layers of son.
- the cable comprises at least one wire reinforcement or armor made of a composite steel with a steel core, of a type standard, covered with a layer of stainless steel.
- the cable comprises at minus a layer of armor made of composite steel wires.
- the cable comprises at at least one reinforcing or armouring wire made of registered trademark 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 tube made of NUOVINOX registered brand composite steel.
- Figure 1 provides a cross-sectional view of an example of a cable telecommunications structure.
- Figure 2 provides a view of a section of an exemplary cable energy transport with reinforced structure.
- FIG. 1 The example of a telecommunications cable with a cross section is illustrated in FIG. 1, is an aerial fiber optic cable, called the guard cable optics, as implemented in high power distribution networks voltage for telesurveillance, telecontrol and / or telecommunications purposes. It is intended to be carried by the pylons of the electrical energy transport network and may therefore be subject to harsh climatic conditions.
- This guard cable comprises a central reinforcing wire 1 around which are arranged in cable tubes 2 each containing a group of optical fibers 3. the wired 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 cabled tubes 2 are arranged either parallel to the central reinforcing wire 1, or wound in a helix around it.
- Armor is placed around the retaining tube 4. It is here composed of two layers of 5, 6 contiguous wires whose diameters are different for the two layers.
- each composite steel wire has a 5A or 6A core of steel, standard type, which is covered with a layer 5B or 6B, in stainless steel. It is the same here for the reinforcement wire 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 registered trademark NUOVINOX, it is obtained from tubes made of stainless steel filled with crushed steel particles which are compressed under high pressure in the tubes. The billets obtained from these tubes are then placed in an oven brought to a temperature of 1250 ° C., then stretched in the form of wires whose respective sections correspond to those desired for the wires of reinforcement and / or armor.
- the stainless steel layer of the composite steel wire corresponds for example to a skin with a thickness of 0.5 mm.
- the hearts of the sons in composite steel may have higher mechanical strength to that of stainless steel, for example if this core is made of carbon steel high resistance.
- cables of telecommunications where it is possible to take advantage of the use of a steel composite for reinforcing or armouring wires and in particular cables for telecommunications comprising coaxial wires or waveguides of material electrically conductive for the transmission of signals in electrical form.
- Figure 2 shows an example of a distribution cable section of armored energy which comprises centrally three conductors with multiple strands of energy distribution 7, for example copper, each of these conductors being coated 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 a single layer, consisting of son 11, arranged in parallel or helically arranged around this tube.
- a sheath armor here a single layer, consisting of son 11, arranged in parallel or helically arranged around this tube.
- At least some of the armor threads are made of composite steel and preferably NUOVINOX, for the purpose of mechanical reinforcement, such as the armor of the telecommunications cable presented in figure 1.
