Line marking

Overhead line: Radar markers, warning spheres

Underground: Signpost, terrain marking, info column

In the overhead line area, markers in the form of usually orange spheres are placed. Some of these also contain radar reflectors (radar markers). They are usually placed on the poles and grounding cables.

High-pressure gas pipelines always have signalization, which is also visible from the air (periodic aerial flight).

Signs will be placed on important armatures in service areas for ease of location. Not only piles, but also buildings, hydrants, etc. serve as installation sites. Designations are signpost, info columns, etc. The attached signs are sometimes also called signs.
