(Field of Industrial Application) The present invention relates to a power cable that can be combined with optical fiber cables used for power distribution in factories and buildings, power transmission and distribution in power generation and substations, etc. (Prior Art) Demand has recently increased for optical/power composite cables that combine power cables and optical fiber cables. A conventional optical/power composite cable is a combination of an optical fiber cable and a power cable at the time of cable manufacture in a factory, as shown in FIGS. 3A and 3B. Figure 3A is an example of a common sheath type optical/power composite cable, in which a power cable core C 1 is provided with an insulating layer 2 made of polyethylene, cross-linked polyethylene, etc. on a conductor 1.
The optical fiber cable 7 is circularly twisted together with an inclusion 6 such as a plastic fiber, and then a plastic sheath 5 made of polyethylene, polyvinyl chloride, etc. is applied. Figure 3 (b) is an example of a triplex type optical/power composite cable, which has an insulating layer 2 made of polyethylene, cross-linked polyethylene, etc. on the conductor 1, and a plastic sheath 3 made of polyethylene, polyvinyl chloride, etc. on the outermost layer. It is constructed by twisting three cable cores C2 and an optical fiber cable 7. (Problems to be Solved) The conventional optical/power composite cable described above has the following problems. At the time of terminal processing for cable termination or connection, in order to ensure extra length, which is essential for work such as optical fiber connections, and to provide slack in the optical fiber cable to prevent excessive tension from being applied, the optical fiber cable is It is necessary to allow longer extra length for terminal processing than for power cables. In order to secure the extra length for terminal processing of this optical fiber cable, the power cable must also be lengthened by that amount, which is uneconomical. If a failure occurs in either the power cable or the optical fiber cable, the entire composite cable must be replaced, which is uneconomical, even if the other cable is sound. Even if it becomes necessary to increase the number of optical fiber cables after the composite cable has been laid, the entire composite cable must be replaced, making it difficult to upgrade the optical system. (Disclosure of the invention) The present invention solves the above-mentioned problems and provides a power cable that can be combined with an optical fiber cable.
This invention is characterized in that the optical fiber cable running pipes are twisted at a pitch that is 15 times or more the diameter of the twisted layer cores. Note that the layer core diameter herein refers to the diameter of a circle passing through the center of each of a plurality of power cable cores. FIG. 1A shows a cross-sectional view of an example of a common sheath type power cable according to the present invention, and FIG. 1B shows a cross-sectional view of an example of a triplex type power cable according to the present invention. In Figure 1A, C 1 is a power cable core with an insulating layer 2 made of polyethylene, cross-linked polyethylene, etc. on the conductor 1, and an internal semiconducting layer on the conductor 1 and an external semiconducting layer on the insulating layer 2 as necessary. Of course, a semiconducting layer or a metal dielectric layer can be provided. A plurality of such power cable cores C 1 and one or more pipes 4 such as polyethylene pipes, polypropylene pipes, etc. for running optical fiber cables are twisted together in a circle with an inclusion 6 such as plastic fibers. A power cable is constructed by extruding a plastic sheath 5 made of polyethylene, polyvinyl chloride, etc. thereon. In addition, in Figure 1B, there are a plurality of power cable cores C2 with a plastic sheath 3 made of polyethylene, polyvinyl chloride, etc. applied over the power cable core C1 in Figure 1A, and at least one power cable core C1. A triplex power cable is constructed by twisting the optical fiber pipes 4. When the power cable described above needs to be combined with an optical fiber cable, the desired light can be obtained by pulling an optical fiber cable having the necessary number of cores and an extra length for terminal processing into the wiring pipe 4. / If a power composite cable can be obtained and the number of cores of the optical fiber cable after installation is desired to be increased, the purpose can be achieved simply by replacing the cable in the wiring pipe 4. In addition, it is better to shorten the twisting pitch between the power cable and the optical fiber cable passage pipe to prevent the core from coming apart when handling the cable and when short-circuiting electromagnetic force (repulsion force) occurs, but it is not too short. and optical fiber cable wiring (using the air-blow fiber construction method, for example, compressed air is used to connect a pipe for optical fiber wiring).

[Table] (Example) An optical fiber cable running pipe composite 6600V cross-linked polyethylene insulated vinyl sheathed power cable having the structure shown in FIG. 2 was manufactured as a prototype. The outline is as follows. Number of power cable cores 3 Conductor Nominal cross-sectional area 80mm 2Outer diameter (approx.) 10.8mm Insulation layer Cross-linked polyethylene insulation thickness (including internal semiconductive layer) (approx.) 4.0mm Shiny annealed copper tape thickness (approx.) 0.1mm Power cable core outer diameter (approx.) 19.0mm Optical fiber pipe outer diameter 19.0±0.5mm Vinyl sheath thickness (approx.) 3.2mm Approximate weight 3720Kg/Km (Effect of the invention) The power cable of the invention described above According to this, the following effects can be achieved. Since the terminal processing of the power cable and the optical fiber cable can be performed independently, there is no need to add extra length to the power cable core, which is economical. If a failure occurs in either the power cable or the optical fiber cable, only the failed cable can be replaced, and the other healthy cable can continue to be used, which is economical. If it becomes necessary to increase the number of cores of the optical fiber cable after the cable is laid, it can be easily done because only the optical fiber cable in the wiring pipe needs to be replaced. Since the optical fiber cable running pipe is twisted at a pitch that is 15 times or more the core diameter of the twisted layer, the length of the optical fiber cable running through the pipe must be made as long as possible for practical use. It has now become possible to provide a power cable that satisfies the two contradictory needs of preventing the wire core from coming loose during cable handling and during short-circuit electromagnetic force.
