Uninsulated 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. High voltage electricity cables are tagged with power=line.
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.

How to Map
Draw a 
way following the path of the cables, adding a node at the location of poles. You can, additionally, then give each of those nodes the tag power=pole. It is not necessary to tag power lines with a layer=* unless two lines cross over each other.
Tagging
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.
- ref=*
- name=*
- operator=*

Rendering
Mapnik renders these as a light gray line at high zooms. Osmarender uses a dashed line with a higher frequency of dashes than a normal power line, again only at high zooms.
