Abstract

A cable network in a duct or pipe system for flowing media has a cable anchored by high-tensile-strength elements between anchoring points in the duct or pipe system. The high-tensile-strength element may be a separate element on which the cable is attached or an element incorporated in the cable sheath. The method includes providing anchoring elements on the interior of the ducts or pipes of the system, and either securing a cable with a high-tensile-strength element to the anchoring elements or securing the high-tensile-strength element to the anchoring elements and then fastening the cable to the tension element.

Claims

1. A communication cable network in a system having ducts and pipes for flowing media, said network comprising anchoring elements at spaced anchoring points in the ducts and pipes of the system, means for securing a high-tensile-strength element to the anchoring elements, and means for fixing a communication cable to the high-tensile-strength element so that the communication cable extends through the ducts and pipes of the system.

14. A cable network according to claim 1, which includes a contact-pressure means being arranged between the anchoring points within the system which can be spread or pressed against the inner wall in such a way that the cable is additionally fixed.

15. A cable network according to claim 14, wherein the contact-pressure means is an expandable and is a glass-fiber-reinforced plastic hose which is provided with an adhesive.

16. A cable network according to claim 14, wherein the contact-pressure means is designed as an expandable ring.

17. A cable network according to claim 14, wherein a removable inflatable sac is arranged within the contact-pressure means in order to spread open the latter and press it on the wall.

2. A communication cable network in a system of pipes and ducts for flowing media, said network comprising a communication cable having an elongated hollow section with at least one high-tensile-strength element secured thereto, anchoring elements being spaced along an interior of the pipes and ducts to form anchoring points, said high-tensile-strength element being secured to the anchoring points by means of the anchoring elements so that the communication cable with the high-tensile-strength element extends through the pipes and ducts of the system.

3. A cable network according to claim 2, wherein a cable is introduced within the elongate hollow section.

4. A cable network according to claim 2, wherein fiber-optic cables, microcables, comprising a small tube and optical waveguides introduced loosely therein, optical-waveguide maxibundles, optical-waveguide strips or electrical cables are arranged in the hollow section.

5. A cable network according to claim 2, wherein at least one high-tensile-strength element is arranged within the cable.

6. A cable network according to claim 2, wherein at least one high-tensile-strength element is arranged outside the cable.

7. A cable network according to claim 2, wherein at least one high-tensile-strength element is arranged in a recess in the cable.

8. A cable network according to claim 2, wherein the cable has a round cross section.

9. A cable network according to claim 2, wherein the cable has a planar or oval cross section.

10. A cable network according to claim 2, wherein a plurality of anchoring units are arranged so that they run parallel.

11. A cable network according to claim 3, wherein the anchoring elements are pegged onto or driven into the anchoring points.

12. A cable network according to claim 2, wherein the anchoring elements are secured on a spreading element, the spreading element being arranged in an inlet location of the system.

13. A cable network according to claim 2, wherein a receptacle for excess cable and/or optical waveguide lengths is arranged in the inlet location, for example within a clamping ring.
