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

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.

Cable fitting for a light waveguide cable, which is secured to a cable of a high-voltage overhead line

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.

Cable sleeve for light waveguide cables

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.

Cassette arrangement for cable sleeves or distributors with each

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

A plurality of light waveguides are conducted side-by-side through a coating arrangement that will surround the waveguides and supply them with a coating material for enclosing the light waveguides to form a ribbon conductor. The light waveguides are guided freely running both proceeding as in the coating arrangement so that they essentially come into contact only with the coating material. A drag flow or entrained flow of the liquid coating material contributes to a self-centering of the light waveguides and is produced by the longitudinal motion of the light waveguides in the coating material of the arrangement.

Method and apparatus for manufacturing an optical ribbon conductor

An optical cable comprising a carrier member extending in a longitudinal direction and having outwardly accessible chambers receiving light waveguides, each of said chambers being separated from one another by a web characterized by a depression being formed in each of said webs to enlarge the heat-emitting surfaces and to remove undesirable accumulation of material in the region of the carrier members. The depressions preferably have a V-shaped cross section, and are smaller than the channels and are able to receive additional elements, which may include waveguides, tensile elements or electrical conductors. Each of the V-shaped depressions can also e used as a gas channel when the optical cable is to operated in a gas-pressure monitored fashion.

Optical cable comprising a carrier member

In the processing of light waveguides, a method uses an overhead haul-off from a first supply reel to apply a pre-twist to the light waveguide, which is preserved during a tinting operation and while the tinted waveguide is wound in a tangential direction on a second supply reel. During further processing, in acordance with the present method, the waveguide is taken off by an overhead haul-off process from the second supply reel in a direction of haul-off which is opposite to the direction during the first overhead haul-off so that the twist produced by the second overhead haul-off is in an opposite direction and compensates for the twist produced during the first overhead haul-off operation.
