|Tools for this tag|
Minor power lines carried on poles physically smaller than the high voltage pylons/towers and used for power distribution, are tagged as power=minor_line. Mostly supported on single poles, although sometimes the poles can have several supports, or may use towers when crossing obstacles where sufficient clearance is required. High voltage electricity lines used for bulk transmission are tagged with power=line.
Minor lines may be anything providing power distribution, from interconnected 20,000 volt lines powering a small suburb, to a single cable running from a street lighting pole to the next one. This tag will apply mostly on the lines that form the distribution grid.
How to map
Draw a way following the path of the cables. The poles that support the minor line can be mapped using power=pole. It is not necessary to tag power lines with a layer=* unless two lines cross over each other.
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. Ground wires are not included. Neutral is not usually counted, other than lines connecting to the end customers.
- power=line For high-voltage power lines, used for bulk transmission, carried on towers (pylons).
- power=cable For insulated underground or sea cables.
