接鉛被覆したものが知られている。Conventionally, the optical unit of an oil-filled power/optical composite cable (a composite cable of an OF cable and an optical cable) consisting of power lines and optical units twisted together has a plurality of cables each having a fiber-reinforced plastic coating (hereinafter referred to as FRP coating). A twisted body of optical fiber core wires and high-tensile strength wires wrapped in paper and further coated with lead, or a twisted body of multiple optical fiber core wires and high-tensile strength wires with a stress buffer layer made of silicone resin, etc. After filling with a gel-like filling system made of silicone resin etc. and molding the whole into a circular cross section, FRP':
It is known that the wire is covered with four layers and wrapped with paper, or directly coated with lead without wrapping with paper.
ところが鉛被覆を施した光ユニットを電力線と撚り合わ

、機械的強度が著しく低下する。The lead coating is very sensitive to external pressure, and when twisted with the power discharge line, it can easily be crushed, or in the worst case, it can be torn, which can have a negative impact on the internal optical fiber core. In order to prevent it from collapsing, it is necessary to eliminate the gap between the lead coating and the stranded body consisting of multiple cored optical fibers and high-tensile wires, etc. We have no choice but to pack in enough interventions. However, if the gap is eliminated in this way, when the power lines are twisted, not only will the external pressure be applied directly to the internal twisted body, but also the internal twisted body will not be able to move locally. When twisting,
Alternatively, this optical unit can be used to alleviate various stresses such as tension, side bending, bending, etc. when installing an oil-filled power/optical composite cable, resulting in deterioration of the characteristics of the optical fiber core wire. Prevents from sticking. In oil-filled power/optical composite cables, after the power lines, optical units, oil supply pipes, etc. are twisted together, they are dried at high temperatures for a long time to dry the paper, but the conditions are that they are left at a temperature of several tens of degrees Celsius for several tens of hours. Under these conditions, the lead coating undergoes thermal deterioration and its mechanical strength is significantly reduced.

、長期間油に浸っている場合は信頼性の保証はない。If the lead coating is torn due to this decrease in mechanical strength or due to the above-mentioned crushing, oil will infiltrate inside. Although the internal optical fiber core has an FRP coating layer, there is no guarantee of reliability if it is immersed in oil for a long period of time.

There is also less worry about losing airtightness. Furthermore, since there is a sufficient gap between the aluminum tube 7 and the 6 layers of paper tape, the internal optical fiber core 2 can move in the cross-sectional and longitudinal directions of the aluminum tube 7. It is possible to relieve stress against lateral pressure and tensile force generated during twisting, or tensile force and bending during laying.

Not only does it have an RP break, but it is also protected by a Teflon protective layer 5 that is rich in heat resistance 1' and 1-, so it will not deteriorate due to heat. In addition, even if the aluminum tube 7 is torn and oil enters from the inclusion 17, 1) the internal optical fiber core 2 will be Also protected from oil.
