Hi all, tower:type=suspension means that conductors or lines (not specific to power) are just linked by vertical insulator. Like this : https://wiki.openstreetmap.org/wiki/File:Einebenenmast.jpg
It is opposed to tower:type=anchor which means that conductors or lines are stopped on the tower Like this : https://wiki.openstreetmap.org/wiki/File:Verdrillmast_Oberwoehr.jpg It is documented here for now, but would deserve a specific wiki page https://wiki.openstreetmap.org/wiki/Tag:power%3Dtower#Tower_type As the use of ":type" is a poor idea and this may not be specific to tower or power, I think about a support:function key to make things clear. We do have poles with anchor, suspension or line termination, for power or telecom wires also. support:function is consistent with support=* used to define any kind of support (pole, pedestal, wall...) for a particular feature. Finally this would be a useful split with values like tower:type=communication which doesn't deal with line attachment at all How do you fell ?
