USSR No. 525832 (publ. 25.08.76), made in the form of two cassettes, in each of which there are inserts tightened on a line, and the inserts are trapezoidal, and each subsequent insert is deployed with a small base to a larger base of the previous one.

This design is difficult to manufacture and operate, low-tech.

The holder for fastening cables and tires according to ed. testimonial. No. 970530 (publ. 30.10.82), containing a base, insulating elements in the form of cylindrical rollers, movably fixed along its longitudinal axis, each of which is made with a groove on the side surface and an end protrusion with parallel flats interacting with the base groove, and fixing bolts installed in the insulating elements, each insulating element on the side opposite to the base is made with two diametrically arranged additional protrusions perpendicular to its end, in which no axial grooves are provided, the flats of the first protrusions are oriented perpendicular to the axis of the grooves, and a fixing bolt is installed in the grooves of each two additional protrusions of adjacent parts.

The holder does not provide reliable clamping of cables having different diameters, which creates inconvenience when working with cables of various sizes.

A known method of laying a cable, described in the book by A.A. Kopteev “Installation of cable networks”. M .: Higher school, 1983, p. 52-53, which consists in combining routes, cables are combined into common streams that are placed on common structures. Depending on the installation method and the number of cables to be laid, single and block constructions of racks and shelves or racks and embedded suspensions are used: wall, ceiling one-sided and double-sided.

Due to the fact that the cable is laid in a common flow - this is a heap of lines on each other, it is difficult to determine in this mess which cable needs to be replaced or removed.

A known method of cable laying is described in the book of L. P. Smirnov “Installation of cable lines”. M .: Energy, 1968, p. 79, which consists in laying the cable flows along the tray, and dividing partitions are installed to separate the cable stream.

The cable is laid in a common stream, which leads to inconvenience in operation.

The cable laying method described in the book by V. M. Chumakov “Wiring and Lighting Electrical Installations” is free from this drawback. M .: Energy, 1967, p. 39, which consists in the routing of the cable.

Laying the cable in rows, without fixing it, is possible only in trays, which limits the application of this method.

There is a method of cable laying, described in the "Directory of the builder of cable communication facilities" authors Baron DA, Gershman B.I., Grodnev I.I. et al. M .: Communication, 1979, p. 322-323, the cable with open laying on brick and other walls is fixed with plate clips or figured clips (brackets).

This mounting method is low-tech, time-consuming.

The proposed method solves the problem of energy saving, manufacturability of installation, ease of operation, the throughput of the structure can be easily changed without prejudice to the process, the attachment of the fastening of the structure can be changed according to circumstances, the shape of the supporting structure can be any, as applied to the terrain.

To obtain such a technical result in the proposed method of laying the cable, communication lines, the base of the device on the supports is attached at any angle to the support and to the subsequent base, and the cable, communication lines relative to the base can be laid at any angle, the base of the devices can be interconnected in different combinations.

Distinctive features of the proposed method are laying the cable, communication lines on the devices, and the base of the devices on the supports is attached at any angle to the support and the subsequent base, and the cable, communication lines relative to the base can be laid at any angle, the base of the devices can be interconnected in various combinations.

To achieve the technical result, the device comprises a base and insulating elements movably fixed along its longitudinal axis, interacting with the base groove with fixing bolts installed in the insulating elements, each insulating element being made in the form of a parallelepiped, and grooves are made in two opposite planes in its middle part trapezoidal shape with the upper base to the center of the parallelepiped, and the insulating elements are made using materials once egg color and they can be made fluorescent.

Distinctive features of the proposed device from the above, closest to it, is that each insulating element is made in the form of a parallelepiped, and in two opposite planes in its middle part grooves of a trapezoidal shape are made with the upper base to the center of the parallelepiped, the insulating elements are made using materials of different color, as well as insulating elements can be made fluorescent.

Due to the presence of these signs, the reliability and convenience of fastening the cable, communication lines are increased, reliable cable fastening of various diameters, communication lines is provided, the complexity of installation work is reduced, and ease of operation is ensured.

The proposed design is illustrated by the drawings in figures 1-12.

A device for attaching a cable, busbars, communication lines contains a base 1 (Fig. 1), which can be made, for example, in the form of a profile with perforation, and insulating elements 2 (Fig. 2) that are movably fixed along its longitudinal axis. The insulating elements 2 (Fig. 3) are made in the form of a parallelepiped with a groove in two opposite planes, in its middle part grooves of a trapezoidal shape are made with the upper base to the center of the parallelepiped, which makes it possible to fasten the cable 3 of different diameters. The insulating element is attached to the base with a bolted connection. The device for fixing the cable, communication lines can be installed on any surface: wall, floor, ceiling, horizontally or vertically. The device makes it possible to place the cable, communication lines in any plane, as well as smoothly switch from one plane to another, which allows you to efficiently and technologically lay cable lines, communication lines along any surface, even despite the difficult terrain. Groups of cables of various brands, types and designs (for example, power, computer, etc.), communication lines can be laid directly under each other, on one device. The possibility of confusion between different cables (and, accordingly, cable groups), communication lines is excluded. In addition, it is easy enough to track the direction of laying of any cable lines, communication lines and, if necessary, quickly and conveniently replace, dismantle or add the desired cable, for this the insulating elements can be multi-colored, as well as with a fluorescent coating.

The method of laying the cable, communication lines is that the cable, communication lines are fixed on the base using insulating elements, and the cable, communication lines are laid on the bases of devices that are mounted on supports at any angle to the support and to the subsequent base (Fig. 4-5), and the cable, communication lines relative to the base can be laid at any angle, the base of the devices can be connected to each other in various combinations (Fig.6-12).

The proposed method is carried out in the following sequence. First, a base is attached to the surface, insulating elements are attached to it, after laying the cable, communication lines, the insulating elements are fixed with tie bolts. The bases of devices on the surface can be mounted differently, depending on the surface topography and the presence of various types of utility networks. The bases of the devices can be interconnected in various combinations (Fig.6-12) and installed along the walls of the premises, suspended from the ceilings, beams and other building elements. The cable and communication lines can be attached to the device’s base from two sides, thereby increasing its throughput. With this laying method, all fire and technical safety rules and PUE are also observed. Cables are cooled by natural ventilation, i.e. The method solves the problem of energy conservation. When using this method, there is no need for transition elements: angular, rotary, planar, moreover, a complex surface topography, special constraint of engineering networks, equipment are not an obstacle for cable laying.

Using this device, you can build trays of any configuration at any distance from the surface (Fig.6-12). The shape of the supporting structure can be any spatial.

When using this device, the reliability and convenience of cable fastening is increased, reliable cable fastening of various diameters, communication lines is provided, the installation work is reduced, this method also allows you to lay more cables, communication lines on a smaller area, and the reliability and ease of use of cable routes increases. Convenience in operation is explained by the fact that the cables according to their functional accessories (power, control, computer, etc.), communication lines are either located on their base, or are indicated by the corresponding color of the insulating element, which makes it easy to trace the circuit from the source to the consumer. The throughput of the structure during operation can be easily changed without compromising the process. The binding of the fastening of the structure can be carried out according to the circumstances: floor, ceiling, wall, column.
