At the same time, it is also possible to preserve the protective effects of cable conduits, which compensate for a considerable part of the voltages induced by the influence of cables in the heterogeneity zone, thus ensuring enhanced security of the communication line.

The invention relates to electrical engineering, in particular, to mounting elements of ship electrical equipment, and can be applied during the installation of a cable network of ships built using a modular-modular method. (The purpose of the invention is to increase the installation capacity and manufacturability while increasing the operational characteristics by reducing the curvature and bending of cables in the area of connecting to the connecting devices. Fig. 1 shows cable wiring; Fig. 2 is the same, top view; Fig. 3 - section A-A in Fig. 1; in Fig. 4 - cable wiring with detachable electrical connectors, cross-section. Cable wiring consists of a bundle 1 belonging to the block module, on which the Cable connection node is located, and a bundle 2, pr proper bundled block module. The bundles 1 and 2 of the cables are located in a common path, in particular in two layers, in the suspensions 3. The cross section of the beam 1 gradually decreases along the path, the cross section of the beam 2 gradually increases along the path with a constant total cross section. the paths of the beams 1 2 are located at least in one set of connecting devices, for example, detachable electrical connections 4 or direct contact connections 5 placed in the casing 6 filled with sealant 7. The casing 6 is located under the route of the beams 1 and 2 in a particular case they may be made of separate sections. The ends 8 of the connected cables are removed from the beams 1 and 2 in the diverging directions and are connected to the connecting devices, for example, the contact connections 5, with opposite sides by a loop 9 covering at least a part of the beams 1 and 2 along the helix 10 The detachable electrical connector 4 or other connecting devices, for example, splicing couplings that do not require additional sealing, can be placed adjacent to any surface on the perimeter of the cable route - side, upper in some: particular cases, if the articulation is easy, then on the surface from the side of the bulkhead. When a block module is installed, through which a bundle of cables passes through, a casing 6 is installed in which the ends of 8 cables are placed in a row. The ends 8 connected to the articulated parts of the detachable electrical connectors 4 are left suspended. When docking an adjacent unit-module, the ends of 8 cables of beam 2, starting from the shortest, alternately lay on cable hangers 3, bring them to fill and evenly pull the cables from the route, connect them to each other with connecting devices - detachable electrical connectors 4, directly splicing using contact connections 5 or in other ways. Contact joints 5 are sealed from the environment by pouring sealant 7 into case 6. When reassembling, sealant 7 is removed from case 6, contact connections 5 are dismounted, for example, unmolded or cut them, pressurized sections, dismount detachable electrical connections 4, break off suspensions 3 and remove bundle cables

2. Similarly, assemble the cables of the new block module. Since the ends of the cables approach the connecting devices in a spiral with smooth parallel loops, almost adjacent to the bundles of the connected cables, which are only at a distance that provides technological reserve for supplying the tool when performing contact termination or for gripping the counter parts of detachable electrical connectors when joining and breaking up, this ensures a small curvature and the absence of kinks in the intersecting planes at the ends of the connected cables. Due to this, extremely high density is ensured; other types of cabling are unattainable; installation density and reduced cable consumption, while maintaining access to all contact connections for accepting work (prior to sealing,) and, if necessary, for diaphragmics and maintenance. Due to the smoothness of the bends and 3 simplicity of laying in a spiral (practically, wrapped around cable bundles, laying at a fixed angle to the track) of the connected cables, the mounting quality is high, especially when connecting powerful power cables. The absence of sharp bends of cable ends and small radii of curvature excludes the occurrence of increased mechanical stresses on the cable sheaths and on the conductors of external surfaces, leading to the occurrence of defects during operation. Due to this, the electrodynamic stability of short-circuit currents in the ship electric power system also increases, since there are no sharp (by 180) turns that change the direction of the current passing through the cable to the opposite and causing repulsion of conductors similar to the connecting device. At the same time, it is also possible to preserve the protective effect of the layers of the wires of the cables, which compensate a significant part of the voltages that are induced by the influence of the cables to a non-uniformity, thus providing enhanced security of the communication line. In the same way, the VSWR value is reduced, which allows to place transmitters and ship radio antennas in adjacent block modules. The invention makes it possible to reduce the size and increase the technical character of the cable connection unit in the case of modular building of ships, and consequently, to expand the field of application of means of electrical installation of electrical equipment in relation to the specifics of building ships for various purposes. Claims of a ship built by a modular-modular method containing cables belonging to adjacent block modules, formed in pairs of parallel beams with a section of one beam gradually decreasing along the route and a section of another beam gradually increasing along the route, fitted with elements for attaching cables to hull structures m and connected to each other by means of connecting devices installed at least in one row along the cable route, so that To increase the density and manufacturability of the installation while simultaneously increasing the performance characteristics by reducing the curvature and cable nepeiib in the area of supplying to the connecting devices, the ends of the connected cables are pulled out of the beams in diverging directions and brought to the connecting devices from opposite sides of the loop, along an envelope along at least part of the surface of the bundled cable bundles.
