| +/- power=minor_line
Minor power cables, supported by poles and not towers/pylons.
Power lines carried on poles physically smaller than the high voltage pylons/towers, are tagged as power=minor_line. Mostly supported on single wooden poles, although sometimes the poles can have several supporting beams.
Minor_lines may be anything from a 20 kV line powering a small suburb, to a single cable running from a street lighting pole to the next one. Be careful not to mistake aerial telephone cables (or the like) for power lines.
There isn't yet any definitive criteria, but 45 kV (and higher voltage) lines are virtually always no longer minor. Also, if the cables are doubled (see wires=*), it is most likely big enough to be better tagged as power=line.
When known, you can also add at least these tags to further define the line:
- voltage=* Nominal voltage (in Volts), for example 20000 or 400
- cables=* Number of the cables carrying currect; Likely values are 1/3/6. The possible lightning protection / shield wire higher than the other cables is not included.
