Marking of underground power lines with the use of warning tapes is of particular importance because of huge threat to the life of people in case of damage to a cable. Marking tapes used for underground power lines are manufactured in two colours:
- – BLUE for cables with the rated voltage of below 1 kV
- – RED for cables with the rated voltage of above 1 kV
Colours and thickness of tapes used for power networks marking is concordant with standards dependent from power network rated voltage. Raw materials and other materials used for manufacture of the tapes guarantee their highest possible quality and strength.
Table of Available Tapes::
CWS boards for cable protection:
|red board||12 – 30 cm|
|yellow board||12- 30 cm|
|red casing||11 – 12 cm|

Marking posts are intended for identification of underground systems route with the use of rating labels/plates. They can be installed in the crucial network points and can be used as the description of the rout. The marking post is made PVC/PE of high performance with the PMMA coating resistant to UV radiation and chalking. The post has a suitable bolt which stabilizes and protects the post from being pulled out.
