した時の把持力が不足し、一体化が不十分となる。FIG. 1 is a perspective view of a specific example of a low-voltage drop-in line with optical fibers formed by the method of the present invention. In the drawing (
I) is a low-voltage power drop-in line with polyvinyl chloride on the conductor,
Consists of one core of insulated wire with an insulating wave M layer made of polyethylene, ethylene propylene rubber, etc., or a multi-core insulated 7-inch wire made by twisting multiple of these insulated wires.(2)
is an optical fiber cable attached to the above-mentioned low-voltage power drop-in line (1). (3) is a spacer that has an inner diameter smaller than the composite outer diameter of the optical fiber cable (2) attached to the power low-voltage drop-in line (1) and has a continuous spiral cut (4). For example, it is a spacer made of polyethylene, It is formed by making a continuous spiral cut (4) in a pipe obtained by molding a plastic material such as polyvinyl chloride, polypropylene, ethylene vinyl acetate, etc., and the spiral cut allows it to be opened. . Also, the inner diameter of this spacer (3) is preferably in the range of 50 to 90% of the composite outer diameter; if it is smaller than this, it will be difficult to attach it to the composite cable, and if it is larger than this, the gripping force will be insufficient when it is attached to the composite cable. However, the integration becomes insufficient.

2) and attach it to the rack, or attach an optical fiber cable to the low-voltage power drop-in line (1) and attach it in parallel. After that, the spacer (3) is opened from the outside of the cable in the composite state along the spiral cut (4),
The low-voltage power drop-in line (1) and the optical fiber cable (2) are integrated at appropriate intervals.

果的でる。In addition, the spacer has a continuous spiral cut, making it easy to attach to electric wires, especially when installing new optical fiber cables required by customers for existing low-voltage power drop-in lines. It is extremely effective in such situations.
さらに、スペーサの内径は複合されたケーブルの外径よ
