Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is directed to the installation of electric wires and cables other than electric power systems at the bottom of utility poles over which high-voltage overhead lines and/or low-voltage distribution lines are installed. Regarding how to.

(Prior technology) Up until now, it was common for telecommunication and power use to be separated and installed on separate utility poles.However, in recent years, the power and communication use have been separated. Due to the lack of clarity and the pursuit of economic efficiency, communication cables, TV public listening cables, L
Electrical wires and cables other than electric power systems that form various communication information networks, such as AN or cable broadcasting wires, have come to be spanned.

The current state of the wiring of these wires and cables to power utility poles is that high-voltage overhead wires are strung across the arms at the top of the utility poles, low-voltage distribution lines are strung below them, and Electric wires and cables other than the power system are strung across the area. This is due to the fact that the electric power company provides the support for the poles, and it is natural to ensure safety such as preventing electric shock.

However, since the wiring of various electric wires and cables other than those mentioned above under these electric power system wires is carried out by different companies, they can be strung as they please, and in severe cases, There are even cables that are strung directly onto utility poles without the use of armrests, which is not desirable in terms of aesthetics, and this tendency is particularly evident in downtown areas and densely populated residential areas.

[Problem to be solved by the invention]

In view of the above, the present invention provides a zone in the span direction for housing the various electric wires and cables other than the power system under the utility pole on which high-voltage overhead wires and low-voltage distribution lines are strung, and in this zone, the electric wires and cables are stored. This is an attempt to beautify the installation of electric wires and cables on poles by storing cables all at once.

[Means for solving problems]

In order to solve the above problems, the electric wire/cable spanning method of the present invention includes a mensenger wire enclosed in both extension side edges, the inner part of the mensenger wire can be opened adjacently, and the bottom part is spaced appropriately. This is a method in which a wire/cable storage tube with holes drilled in it is strung between utility poles, and wires/cables other than the power system are stored in the wire/cable storage tube.

[Effect]

The extended side edge of the electric wire/cable storage cylinder strung between utility poles can be opened adjacent to it, making it easy to store and take out electric wires/cables, and various electric wires/cables other than power systems can be stored all at once. . Further, by perforating the bottom of the wire/cable housing cylinder at appropriate intervals, it is possible to drain the inside of the wire/cable housing cylinder in a stretched state (curved state).

〔Example〕

First, the electric wire/cable storage cylinder used in the spanning method of the present invention will be explained based on FIGS. 1 to 3.

In Fig. 1, a wire/cable storage cylinder 1 is formed by extrusion molding into a cylinder 2 with both extended side edges 2a and 2b that can be opened, and mensengers are attached to both extended side edges 2a and 2b. The wire 3 is covered with a coating. Both extended side edges 2a2b can be opened adjacent to each other, so that electric wires and
The cable can be stored or taken out by expanding both extended side edges 2a and 2b. Therefore, the cylindrical body 2 is made of a material that is elastic or flexible at room temperature.

Drain holes 4 are bored at appropriate intervals in the bottom of the electric wire/cable storage cylinder 1 (on the opposite side of the measuring wire 3). The purpose of this water drain hole 4 is to prevent water from entering the inside of the electric wire/cable housing cylinder 1 when it is strung over a utility pole or the like. Therefore, it is preferable to drill the drain holes 4 at intervals that can prevent water from entering even in the bridged state (curved state). The method for forming the cylinder body 2 into a cylinder body with open side edges is as follows: - First, a sheet-like material with the mesh wire 3 coated and enclosed on both extended side edges is extruded, and then it is transformed into a cylinder body. There is a method to solidify it.

In FIG. 2, the wire/cable storage cylinder 11 is the cylinder 1.
2 is molded into a necked cylindrical body with open side edges, and both extended side edges 12a, 12b of the neck portion 15 are covered with a messenger wire 13. Both extended side edges 12a, 12b and neck 15 can be opened adjacent to each other, and electric wires/cables can be connected to both extended side edges 12a, 12b and neck 15.
5 can be expanded for storage and removal.

Further, similar to the electric wire/cable storage cylinder 1 shown in FIG. 1, drain holes 14 are bored at appropriate intervals in the bottom thereof. When the electric wire/cable storage cylinder 11 having the neck portion 15 is installed on a utility pole, it is easy to attach a clip or a hanging fitting to the mesosenger wire 13 portion.

In FIG. 3, the electric wire/cable storage cylinder 21 is replaced by the cylinder 2.
2 is formed into a necked cylinder with open side edges and a spaced interval "L", and a messenger wire 23 is coated and enclosed on both extended side edges 22a and 22b of the neck portion 250. Both extended side edges 22a22b and the neck portion 25 are integrally adjacent to each other and can be opened, and electric wires/cables can be connected to both extended side edges 22a,
22b and neck 25 can be expanded to allow storage and removal. Further, like the electric wire/cable storage cylinder 1 shown in FIG. 1, drain holes 24 are bored at appropriate intervals in the bottom thereof.

Next, a method for spanning electric wires and cables will be explained using the electric wire and cable storage cylinder 11 shown in FIG. 2 as an example. As shown in FIG. 4, the electric wire/cable storage cylinder 11 is suspended from the arm 32 of the telephone pole 31 by means of a hanging fitting 33. Then, both adjacent extendable side edges 22a, 22b and the neck portion 25 of this electric wire/cable storage cylinder 11 are pushed open and electric wires/cables 34 other than the necessary power system are inserted. This insertion work can be performed before or after hanging the cable from the utility pole 31.

Furthermore, the branching method of the inserted electric wire/cable 14 is explained in the fifth section, taking the electric wire/cable storage cylinder 11 shown in FIG. 2 as an example.
This will be explained using figures. At the part where branching is required, the neck part 15 is cut in the length direction, and the screws 38 and 39 of the clamps 37a and 37b installed upright on the base plate 36 are loosened at this part, and both extended side edges 12a12b are stored as they are, and the extruded body 12 is inserted through the bushing 40, and the rod 41 that maintains the clamp interval is passed over the top of the clamps 17a and 17b, and the screw 38 is inserted.
．． Tighten 39. A terminal block 42 is attached to the base plate 36.
The electric wires and cables that are provided and branched are branched at a terminal block, and a branch line 43 is drawn out from the lower part of the terminal block.

Side plates 44 are fitted to the front and rear of the base plate 36, and the side plates 44
A through nozzle 45 is provided where the cylindrical body 12 and both extended side edges 12a and 12b pass through, and a vertical slit is provided in this nozzle 45 so that the cylindrical body 12 and both extended side edges 1 pass through each other.
2a and 12b expand this slit and push it in. There are dovetails and dovetail grooves on the opposite side of the slit, which engage and become integrated. A cover 46 is placed over the tops of the clamps 37a and 37b, and the inner surface of the cover, the side plate 44, and the base plate 3B are engaged with each other at dovetail grooves and are integrated to form a terminal box.

In addition, as shown in FIGS. 1 and 3, if both extended side edges or the cylindrical body cannot be held as they are, the shape of the clamp, etc. may be changed.

〔Effect of the invention〕

The present invention includes a messenger wire in both extended side edges,
The electric wire/cable storage tube with the inner part of the wire/cable that can be opened next to each other, and the bottom part is perforated at appropriate intervals, is spanned between the utility poles, and electric wires/cables other than the power system are bundled inside the electric wire/cable storage tube. Since it is stored, it is possible to achieve beautiful installation of electric wires and cables on poles. In addition, by reopening the Mensenja wire internal packaging, it is possible to store electric wires and cables.
Since it is easy to take out and drainage is possible through appropriately spaced perforations in the bottom of the storage cylinder, construction such as bridge work can be done easily and drainage can be ensured.
