Informationcablenetwork in a duct or tube system primarily used for other purposes

摘要

The communication network is based on cables consisting of a flexible core (7, 8, 9, 10) and a shell (11) whose stiffness is such that the maximum cable deflection between two adjacent fixing points distanced at 2000 mm from one another is less than 20 mm. In the region of shafts of the channel or piping system, the cable shell is distanced from the cable core.
