Electricity pylon DSCI0402.jpg
design asymmetric A two- or three-level tower carrying only one circuit and having the conductors arranged in an asymmetrical layout.
60 kV tower (Denmark)
design triangle A sub-type of the asymmetric tower. It has cross-arms at three levels providing a triangular arrangement of the conductors.
60 kV angle tower (Denmark)
design flag A sub-type of the asymmetric tower. All conductors are located at one side. The tower typically has no or only rudimentary crossarms. This tower type is usually used as an angle tower.
design donau;one-level A three-level combination tower effectively being a Donau tower having an additional lower level, often used for circuits of a lower voltage than those at the upper levels. This tag better describes the design than just using "three-level". Similar tag values may be used for other designs having an additional lower level.
Pylon Shenzhen.jpg
design four-level,
A tower having cross-arms at four or more levels. These tall towers may carry four or more circuits.
150 kv tower (Denmark)
design delta A y-shaped tower having a horisontal cross-beam between the two top structures. All conductors are attached to the cross-beam. It is mostly used for a single circuit.
150 kV tower (Netherlands)
design delta_two-level
Delta tower having two or three cross-beams. Suitable for three circuits.
400 kV tower (Denmark)
design y-frame Similar to delta tower but there is no horisontal cross-beam between the two top structures. The middle conductor is supported directly by the top structures.
design x-frame A variation of the y-frame tower having two legs. It is suitable for carrying a second lower voltage circuit on a crossbeam below the joint.
60 kV wooden tower (Denmark)
design h-frame A tower type having two (or more) separate pylons or poles connected by a beam to which the conductors are attached. The cross-beam extends beyond the vertical structures such that not all conductors are located between the vertical structures. The portal tower is mostly used for a single circuit.
33 kV wooden tower (UK)
design h-frame_two-level
Designs like the h-frame tower, but having cross-beams at two or three levels.
design guyed_h-frame A guyed version of the h-frame tower supported by guy wires, common in e.g. Scandinavia. Compared to the self-supporting h-frame tower this design normally has non-vertical legs. This detail is useful for distinguishing self-supporting towers from guyed towers in aerial imagery etc, since the guy wires are usually too thin to be directly visible in such imagery.
Portal tower at Kassø substation (DK)
design portal A tower type having two (or more) vertical structures connected by a horisontal cross-beam. All conductors are supported between the vertical structures (unlike the h-frame tower). This design is mostly used as termination tower at substations.
design portal_two-level,
Two and three level versions of the portal tower.
735 kV tower (Quebec)
design guyed_v-frame A guyed tower type that is mainly used for ultra-high voltage lines e.g. in North America.
380 kV Wintrack tower
design bipole A pair of closely spaced but non-touching pylons. The conductors are typically mounted between the pylons. There are no cross-arms. Known as 'Wintrack' in the Netherlands. The bipole should be mapped as a single tower.
400 kV anchor towers (Denmark)
design monopolar A tower having no cross-arms, with insulators mounted on the tower itself. Mostly used as an anchor tower at very high voltage, but also used as both suspension and anchor tower carrying all three phases on urban high voltage lines. Towers of this design can be either lattice or tubular steel, wood, or concrete.

This tower type is typically used in groups of three, with each carrying one phase, but may carry all phases in one tower. There are two recommended options for mapping such a group. Either map all three towers and connect the power line to the middle tower. Or map only one tower and add the attribute triple_tower=yes to the tower.

design:name * When the tower design has been given a specific name by its designer it can be indicated by this tag, such as Wintrack (The Netherlands), Eagle (Denmark).
150 kV tower (Denmark)
design:incomplete yes An incomplete tower carries less conductors than the design is capable of. Sometimes the unused cross-arms are omitted (but can be retrofitted if an extra circuit is to be mounted)


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.

Picture Key Value Description
Elbekreuzung 2 traversen crop.jpg
tower:type suspension 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)
tower:type anchor 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.
tower:type termination 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.
Branch tower
tower:type branch 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.
Verdrillmast Oberwoehr
tower:type transposing A tower in which the conductors exchange positions in order to balance the capacitance and impedance of the conductors.
Bosphorus Crossing
tower:type crossing A special tower used at river crossings etc where a very long span or a large clearance is required. These towers may be very tall and are therefore significant landmarks.
Sindelfingen Gesockelter Mast 2007 by-RaBoe 03.jpg
location:transition yes This attribute denotes that one or more circuits transition to an underground cable in this tower. The cable terminals are located in the tower itself (no fenced area on the ground). The key location:transition=* replaces the values tower=transition and tower=air_to_ground which should no longer be used.
For fenced transition stations with cable terminals on the ground use power=substation and substation=transition
