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.
