|Tools for this tag|
A power line is carried on power=towers. Three cables are one circuit (except power for train and HVDC). Every circuit has one voltage=* level on which it operate. Draw one way for all circuits connected to one power tower. All lines for 50 kV or more are power=line. For less voltage than this use power=minor_line on power=pole. Use power=cable with location=underground for undergound power supply. name=* should be used for name/number of the line (can be found on power towers).
Power towers have numbers and names on it. Tower numbers increase from start to end point. Names or Numbers for each systems can be found on power towers and are the same at each tower. These belong to the power=line and should be taged on the way itself. Use source=survey if you track them! Poles only carry power=minor_lines. Power towers can also carry power=minor_lines.
How to Map
Draw a way and add the power=line to it. The towers that support the power line can be mapped using power=tower. It is not necessary to tag power lines with a layer=* unless two lines cross over each other.
It is possible to connect power lines to power=portal inside power=substation using power=insulator on the connecting node.
power=terminal is also used at the connection with buildings without a dedicated power tower or portal to support the end of the line.
It is also possible to give some additional and advanced information about power lines :
- The number of wires=* per conductor.
- You may look at cables=* for the number of power-carrying conductor (bundles of wires) the line is composed of.
- circuits=* corresponds to the number of electrical circuits (logical bundles of cables). The tag may be used when the number of physical cables is unknown (often the case for underground cable connections) or when the number of circuits is different from cables=* divided by 3 (or by the number of phases of the line).

Since power lines cables aren't insulated, they can only be located overhead to protect them from grounding with external elements.
"wires" means the type of cable which hang on isolators. Possible values : single, double, triple, quad .. (table from User:Nahainec/PowerLine)
