Key:pole:type

This feature has been labeled as deprecated. The recommended replacement is: line_management=*.
The reason is documented in Deprecated features. You are still free to continue to use or interpret this tag as you see fit since OpenStreetMap does not have “banned features”.
Under no circumstances should you (semi-)automatically change “deprecated” tags to something else in the database on a large scale without conforming to the automated edits code of conduct. Any such change will be reverted.

This tag describes the functional type or role of a power pole, such as a dead-end (anchor) pole.

See also line_attachment=* to state how the supported line is bound to the support.

Key	Value	Description
pole:type	termination	A pole 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.
pole:type	branch	A line branch starts at this pole. 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.
