|power = cable|
|An insulated cable carrying electrical power, such as transmission or distribution cables located underground and undersea cables|
|Used on these elements|
|Status: de facto|
|Tools for this tag|
A cable is insulated and allows electrical power transmission or distribution in complex environments such as indoors, underground or undersea.
These heavier cables should not be confused with light-weight power distribution lines supported by poles, for which power=minor_line is more appropriate. For wires and cables used to communication data, voice or information, consider using communication=line. Overhead lines supported by pylons (power=tower) are tagged as power=line.
How to map
Draw a line along the feature path and tag it with power=cable. By default, cables are assumed to be buried underground or underwater and location=* can be used with appropriate value.
- Optionally add layer=* if needed to indicate the relative vertical alignment of different features.
- For cables mounted inside a man accessible self-supporting tunnel use tunnel=yes. Dedicated and accessible power tunnels are sometimes found in large cities like London
Cables, as power lines, are physical features mapped as ways which don't represent the flow of power.
- It is recommended, if known, to cut ways as often as cables are joined together. It is important to document differences (diameter, material and so on) between cable sections.
- Cables - like power lines - can be members of route=power relations corresponding to a whole power circuit between two substations.
|power||cable||It's a power cable, normally mapped as a .||Mandatory|
|voltage||<operating voltage>||The voltage at which the cable is operated||Recommended|
|location||<location>||The physical location of the cable, such as underground. See below for possible values. The default value is underground||Recommended|
|operator||<cable operator>||The name of the company which operates this power cable section||Recommended|
|cables||<number of cables>||The number of different phase conductors for this power cable section||Recommended|
|circuits||<number of circuits>||The number of different and separated electrical circuits built within this cable section||Recommended|
|frequency||<operating frequency>||The frequency given in Hertz at which the power cable is operating||Optional|
|name||<name>||The name of this power cable section.||Optional|
|ref||<reference>||The reference of this power cable section||Optional|
|location||underground||A cable buried underground (below terrestrial ground or undersea) going through ducts or not. This is the default value.|
|indoor||A power cable located inside a building or a way larger underground infrastructure|
|underwater||A power cable located on the sea/river/lake floor, which can be seen when diving without digging soil.|
|overground||A cable installed on the ground (it is possible since power cables are properly insulated and it makes the main difference with power lines).|
|overhead||A cable installed on poles. They can be seen in forests or narrow environments. This makes a strong difference with uninsulated power lines, more vulnerable to climate impacts.|
location:transition=yes may be used on nodes connecting two different cable sections with different location=*s. It is even better on the end node of a power line or cable disappearing underground without more knowledge.
How to detect an underground cable
Common tagging mistakes
|High voltage cables suspended on the walls of a technical tunnel underground|
|Overhead cables suspended on wooden poles|
As limited visibility features, cables are not rendered on the standard OSM Carto map. The following services do show cables:
- Open Infrastructure Map offers a Electricity distribution view (available globally). Power cables are shown as dashed lines.
- Maperitive power line rule set for rendering power lines, cables and substations in Maperitive.
