Cable network in a system of ducts and pipes having a flowing media and a method of securing the network in the system

The invention relates to a method for securing cables in a duct or pipe system for flowing media, such as gas, waste water, rain water or mixed water. 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.
