design=donau_inverse

I'm using this tag for the donau-type, where the wider arms are on the top with two insulators and one insulator on the bottom arms. One system in shape of a 'v'. So another possible name/symbol would be 'w' or 'vv' for two systems. Here is a good example:. 292829257 292829257 see ESRI or Bing background. --Bahnpirat (talk) 14:37, 28 September 2021 (UTC)

Didn't know about such a design. Could you check if I drew the icon right? Donau: , inverse donau: . Enzet (talk) 05:33, 28 September 2021 (UTC)

The symbol is fine and fits good. I know only 3 lines with this design. All in Thuringia, Germany. More regular (but only on short distances) would be a two-level-tower with top level 2x 3-phase 110 kV, 50 Hz and the lower level would be 2x 2-phase 110 kV, 16.7 Hz to supply energy to trains. (substation=traction). The design looks the same. Thanks. --Bahnpirat (talk) 14:37, 28 September 2021 (UTC) There is also one tower in Brazil in the State of São Paulo and it has line_management = transpose.Owen C 200 (talk)

Slovak "Macka" tower and it's design

Tower design informally called "mačka" is pretty common in Slovakia (also saw few of them in the Czech Republic). It is carrying one circuit with conductors at two levels and in triangular arragment - suspension, anchor tower. How should I tag this design? design=two_level, design=triangle (conductors only at two levels) or design=y-frame (there is a horizontal cross-beam between top structures). --Chiak (talk) 16:33, 30 April 2022 (UTC)

two poles through-bolted

How to tag two poles that are bolted together and then have an arm https://westnordost.de/p/92284.jpg I don't think it counts as H frame (pi pole) because there's no gap between them but maybe that's okay. It's basically like a pole but there are two so I guess it should be power=tower? Thanks TrekClimbing (talk) 22:18, 8 September 2022 (UTC)

Separating the "guyed" tag

I would suggest we move guyed to a separate tag. Simply guyed=yes. Reason being almost any tower design can use guy wire to support them if ground condition is poor or the angled tension is to great. There is already quite a few designs that start with "guyed" so it would simplify this list. Gazer75 (talk) 07:42, 2 June 2024 (UTC)

It's quite chaotic. The ~5k guyed=* listed on Key:design#Poles is already used on power=pole , but Proposal:Power pole extension didn't cover power=tower , causing this situation.
I support separating *=guyed_* from both here, and tower:construction=* , especially because both tower:construction=lattice and tower:construction=freestanding (should be tower:construction=tube instead to match tower:construction=guyed_tube in the first place) are free-standing. Furthermore, man_made=cross and natural=tree are mentioned in in Tag:man_made=guy_wire , but without such an attribute.
I suggest using support=* somehow, although that is quite messy now. Or start reinforcement=* / reinforced=* , if there is a need to show additional supporting structure outside the original thing. This allows supports other than wires to be added.
