The invention concerns a method for securing cables or elongate hollow sections in duct or pipe systems for flowing media, and a cable network in a duct or pipe system. The cable or elongate hollow section to be laid is anchored by high-tensile-strength elements between anchoring points. The high-tensile-strength element may be a separate element or an element incorporated in the cable sheath or in the hollow section. Furthermore, the invention concerns the reduction of sags.

Method for securing cables in duct or pipe system

To protect a waveguide or cable in an installation channel, a protective profile is inserted into the channel and has a substantially U-shaped cross-section when installed. To install this in the channel, an apparatus having a drum with a profile wound thereon has the profile unwound and guided by guide rolls to a press roll, which presses the profile into the channel to the desired depth. The profile can have a center portion provided with embedded reinforcing elements or even optical or electrical leads.

A cable network with a light waveguide cable which is introduced in the pipeline of an existing pipeline system. The light waveguide cable is arranged along a line, preferably at the vertex of the pipeline, and is provided with a protective layer so that a smooth transition exists between the wall surfaces of the pipeline and the cable.

The insulator is constructed in two parts and can, therefore, also be fastened to an already-laid ADL cable. The two glued insulator halves, which are reinforced by sleeves that are pushed on at the end, are each made of a half-pipe having transverse and longitudinal stability, as well as an insulator element that partially surrounds the half-pipe. A casting resin brought into the cylindrical hollow space of the insulator connects the half-pipes sealed at the end with silicone stoppers, the GFK rod, and the cable to form a stable unit.

A method for drawing a cable which inherently lacks tensile strength into cable channels or cable pipes includes providing a tensile yarn skin on the end of the cable before the step of drawing the cable into the channels or pipes. The yarn skin can either be a net hose or a spin-wrap applied onto the cable. One application of the method is the connection of the cable incoming at a terminal tower to a switching center or exchange.

The invention provides a cable fitting which receives light waveguide cables, which are supported by high-voltage overhead lines, or their light waveguide splices and excess lengths. The light waveguide cables are secured to a ground cable or a phase cable of a high-voltage overhead line by a bracket and are decoupled from the high-voltage via an insulator on a down-lead to the cable fitting.

A method of installing an optical cable on a conductor of a high-voltage line comprises helically wrapping the cable and conductor with an adhesive tape.

A cable sleeve for light waveguides is constructed as a flat plate member in which a circular groove extends and has inlets extending tangentially from the groove. The cable sleeve can receive excess lengths of the cable as well as splices which excess lengths and splices are received in the circular groove.

A cassette arrangement for cable sleeves or distributors is composed of a plurality of cassettes for light waveguides. Each cassette is mounted for pivotable movement between a storage position and a working access position. Each cassette has a pair of deflection elements with circumferential channels for receiving the excess lengths of the light waveguides which are stored in the cassette.

A method and device for on-site producing a cable at the location for placing the cable includes a mobile device supporting an arrangement for forming a protective sheath of the cable and an arrangement for inserting the optical fibers or electrical leads into the sheath and then discharging the sheath into a cable laying position. The device may include an arrangement for forming a trench for receiving the cable, an arrangement for inserting a filling compound into the interior of the sheath as the leads or fibers are introduced therein and means for supplying a filling material for filling the trench subsequent to insertion of the cable therein.

Method and device for producing a cable

A process and apparatus for introducing a cable into a channel, which is formed into a heated surface of solid ground, such as asphalt, displaces the material to form a channel, inserts the cable and then reintroduces the displaced material back into the channel to refill the channel.

Process and apparatus for introducing an optical or electrical cable

An optical cable comprises at least one bundle composed of a plurality of light waveguides which are preferably wrapped as a layer on a cable core. A non-hardenable filling compound is provided on the inside region of the light waveguide bundle between the layer of waveguides and core and the outer surfaces of the layer of optical waveguides is coated with a hardenable compound.
