Measures for mechanical protection
The following measures are recommended to protect bus cables from physical damage:
● When cable cannot be installed on a cable rack or similar construction, it should be
● In areas where the cable is subject to mechanical stress, install the cable in a heavy-
● When 90° bends are necessary and at the junctions between buildings (for example
● In areas where the cable is likely to be walked on or driven over in buildings or in
