[0026] The following specific embodiments illustrate the implementation of the present invention, and those familiar with the technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0027] See also Figures 1 to 6 The utility model provides an optoelectronic integrated bundled cable for an intelligent power station, comprising an electric unit 1, an optical unit 2, a radio frequency unit 3 and a network cable unit 4 arranged in a matrix, the outer sides of the electric unit 1, the optical unit 2, the radio frequency unit 3 and the network cable unit 4 are all covered with an outer sheath 5, and a hinge 6 is connected between adjacent outer sheaths 5. The electric unit 1 comprises a plurality of conductors 11, an insulation 12 coated on the outer side of the conductor 11, and a braided layer 13 covering the plurality of insulations 12 together; the optical unit 2 comprises at least two composition modes; the radio frequency unit 3 comprises a conductor 2 31, an insulation 2 32, a semi-conductive layer 33 and a shielding net 34 arranged in sequence from the inside to the outside; the network cable unit 4 comprises a cable core, a sheath 43 and a shielding layer 44 arranged in sequence from the inside to the outside.

[0028] The utility model forms an optoelectronic bundled cable by combining an electrical unit 1, an optical unit 2, a radio frequency unit 3 and a network cable unit 4, which has the characteristics of small size and convenient laying. When needed, the above four units can be flexibly combined in different ways to meet different needs. By adding a braided layer 13 to the electrical unit 1 and a semi-conductive layer 33 and a shielding net 34 to the radio frequency unit 3, the anti-interference and anti-noise capabilities of the communication power line and the radio frequency line are further improved, which can be applied to the communication and power supply needs between smart grid equipment, and can also be used for power supply and multi-purpose communication transmission between warships, ships, and underground tunnel communication equipment.

[0029] The optical unit 2 is composed of a plurality of tight-buffered optical fibers 211, an inner sheath 213 sleeved outside the plurality of tight-buffered optical fibers 211, and aramid 212 filled between the tight-buffered optical fibers 211 and the inner sheath 213. The tight-buffered optical fiber 211 is a protective sleeve sleeved outside the optical fiber 221, and the protection of the sleeve reduces the influence of external stress on the optical fiber 221, thereby reducing the static fatigue of the optical fiber 221 and extending the service life of the optical fiber 221; the setting of the inner sheath 213 can further protect the tight-buffered optical fiber 211, has the functions of waterproofing and moisture-proofing, and can increase the tensile, compressive and bending resistance of the optical unit 2; the aramid 212 has the characteristics of high strength, low expansion coefficient, and chemical corrosion resistance, and can effectively fill the inside of the tight-buffered optical fiber 211, thereby improving the durability and tensile strength of the optical unit 2.

[0030] The second composition of the optical unit 2 includes a central reinforcement member 224, a plurality of PBT tubes 223 and a core filling 226 closely arranged on the periphery of the central reinforcement member 224, a water-blocking layer 227 coated on the outside of the PBT tube 223 and the core filling 226, and a cable paste 225 filled between the PBT tube 223 and the core filling 226; a plurality of optical fibers 221 and a fiber paste 222 filled between the optical fibers 221 are arranged in the PBT tube 223.

[0031] The central reinforcement 224 is provided to increase the overall mechanical strength of the optical unit 2 to prevent damage by external forces during the laying process. The PBT tube 223 has a certain flexibility and is corrosion-resistant and wear-resistant, and can well protect the internal optical fiber 221. The optical unit 2 has strong water absorption during the construction process, which may cause water penetration and damage to the optical unit 2, affecting its normal use. Therefore, a water-blocking layer 227 is provided to ensure the normal use of the optical unit 2 and increase the service life of the optical unit 2.

[0032] The cable core is formed by twisting four groups of insulating cores, each of which is formed by twisting two insulating cores, and each insulating core is composed of a conductor 41 and an insulating core 42 wrapped around the outside of the conductor 41. When the transmission line is long, since the loop area formed by each pair of insulating cores is too large, the crosstalk and external interference between the insulating core pairs are very serious. In order to reduce the crosstalk and external interference between the pairs, only the "cross" technology can be used, that is, each pair of insulating cores for parallel transmission are twisted with each other according to a certain degree of tightness, so that the loop formed by each pair of lines can be divided into several small loops, and the induced crosstalk and interference in each loop can offset each other to a certain extent, thereby achieving the effect of reducing crosstalk and interference, thereby maintaining the stability of the transmission network.

[0033] The number of the electrical units 1 is 1-3; the conductor 11 is a copper conductor; the material of the insulation 12 is polyethylene, cross-linked polyethylene or low-smoke halogen-free flame-retardant polyolefin; the material of the braided layer 13 is copper wire.

[0034] The braided layer 13, the shielding layer 44 and the shielding net 34 in the present application are made of copper wire. The current path of the copper wire is shorter, so the output heat is also less. The number of the optical units 2 is 1-3; the number of the tight-buffered optical fibers 211 is 1-48 cores; the material of the inner sheath 213 is polyethylene or low-smoke halogen-free flame-retardant polyolefin.

[0035] The central reinforcement 224 is FRP or phosphating steel wire; the number of the optical fibers 221 is 1-144 cores; the material of the water-blocking layer 227 is water-blocking tape. The number of the radio frequency units 3 is 1-3; the conductor 2 31 is a copper conductor; the material of the insulation 2 32 is polyethylene or cross-linked polyethylene; the semi-conductive layer 33 is a semi-conductive plastic composed of a mixture of carbon black and polyolefin, and the volume resistivity of the semi-conductive plastic is not greater than 100Ω·m; the material of the shielding net 34 is copper wire.

[0036] In the present application, conductor 1 11, conductor 2 31, and conductor 3 41 are all copper conductors. Copper has good electrical conductivity and a very high conductivity. Copper also has good corrosion resistance and ductility and can be easily processed and formed. The semi-conductive layer 33 can exert a uniform electric field and, when combined with the shielding net 34, can effectively eliminate the generation and mutual influence of weak electrical interference signals caused by the internal structure of the cable.

[0037] The number of the network cable units 4 is 1-3; the conductor 3 41 is a copper conductor; the material of the insulation 3 42 is polyvinyl chloride, polyethylene or flame-retardant polyolefin; the material of the sheath 43 is a polyester tape; the material of the shielding layer 44 is a copper wire. The insulating material in the present application has good insulation and flame retardant properties, is not easy to burn in the event of a fire, and can play a role in fire prevention; the setting of the sheath 43 can prevent multiple insulated wire core groups from being loose, and can prevent data signals from being affected.

[0038] The outer sheath 5 and the hinge 6 are made of polyolefin, specifically one of flame-retardant polyolefin, low-smoke halogen-free flame-retardant polyolefin, and flame-retardant polyethylene; the outer sheath 5 and the hinge 6 are extruded simultaneously. During use, one or more hinges 6 can be torn open as needed to form one or more groups of parallel bundled cables, which can be laid in parallel as needed, laid in place in sequence, and save space, and have the characteristics of simple installation and low maintenance cost.

[0039] The utility model structure is a multi-purpose photoelectric integrated bundled cable for communication and power supply between smart grid equipment, and can also be used for power supply and multi-purpose communication transmission between warships, ships, and underground tunnel communication equipment. The utility model has a flexible unit combination mode, and can be bundled and laid after different unit combination processing according to the actual use needs of the equipment. At the end, one or more hinges 6 can be removed according to the spacing between the device sockets to facilitate wiring. It can be laid in a variety of ways such as pipelines, along walls, and bridges, saving space, and can be laid in place at one time, with a low overall cost.

All equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
