These tall towers may carry four or more circuits.Ī y-shaped tower having a horizontal cross-beam between the two top structures. Similar tag values may be used for other designs having an additional lower level.Ī tower having cross-arms at four or more levels. This tag better describes the design than just using "three-level". This tower type is usually used as an angle tower.Ī 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. The tower typically has no or only rudimentary crossarms. It has cross-arms at three levels providing a triangular arrangement of the conductors.Ī sub-type of the asymmetric tower. It is characterized by the middle level cross-arms being longer than the upper and lower cross-arms giving the conductor arrangement a barrel-like shape.Ī two- or three-level tower carrying only one circuit and having the conductors arranged in an asymmetrical layout.Ī sub-type of the asymmetric tower. The "Donaumast" is widely used in central Europe.Ī tower having cross-arms at three levels.Ī common sub-type of the three-level tower. It is characterized by having one conductor on each side at the upper level and two conductors at each side on the lower level. See examples with suggested values below.Ī tower having cross-arms at a single level only supporting a 110 kV line.Ī tower having cross-arms at two levels supporting a 150 kV line.Ī common sub-type of the two-level tower supporting 400kV line in Denmark. Cross-arms which only serve as support for earth wires should not be considered. The main parameters are the number and positions of cross-arms. This tag describes the design of the tower. The name of the company that build the tower. Particular arrangements of line bundles supported by the tower The colour(s) of a painted tower e.g., colour=red/white for tower painted red and white to make it better visible to pilots.Īny particular topology pattern occurring around the support for supported lines. The height in meter of the tower if known. The reference of the tower as seen on ground. The name of the company operating the pole (the one who comes after storms to make some repair for instance). For wooden or concrete towers the default is solid. For steel towers (or if no material tag is specified) the default value is lattice. This tag describes the construction type of a tower. The material of which the tower is mainly composed. You can add additional information about the tower using the following tagging scheme. To mark towers where the line is connected to an underground cable use line_management= transition and/or location:transition= yes. The power= line or lines which are supported by the tower should share the same node. You can add a ref=* as well if the tower has a number. It does not store any personal data.Add a node at the centre of the tower and add the power= tower tag.
