Available languages — Key:pole:type
This tag describes the functional type or role of the transmission tower, such as anchor tower. Please note that the tower:type=* tag has other meanings when used in combination with man_made=tower.
||A tower which supports the conductors vertically using suspension insulators. This is the default type and need not be tagged. However it may be useful to tag a suspension tower if it is used as an angle tower (an anchor tower would normally be expected here)
||A tower where conductor sections terminate at strain insulators. It is normally built stronger than suspension towers. Mostly used as angle tower when the line changes direction.
||A tower with strain insulators used at the end of a line, for example at a substation or at the transition to an underground cable (add location:transition=yes). Designed to resist the full one-sided tension of the conductors.
||A line branch starts at this tower. If the branch line is a cable then add location:transition=yes. The branching can take different forms which can be indicated by the following tags.
- branch:type=tap The conductors of the branching circuit(s) are electrically connected to the 'through' circuit(s).
- branch:type=split The circuits arriving at this tower continue in different directions.
- branch:type=loop A circuit departs in the branch direction and another circuit arrives from the same direction to continue in the 'through' direction. Typically used for 'looping' one circuit into a nearby substation.
- branch:type=cross Two otherwise unrelated power lines intersect here and use this tower as a common support.
