A cable is often insulated and allow power transmission or distribution in complex environments and even underground or undersea.
Use power=cable for any voltage.
These heavier cables should not be confused with light-weight uninsulated power distribution lines supported by pylons and poles, for which power=line/power=minor_line are normally more appropriate. For wires and cables used to communication data, voice or information, consider using communication=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.
Use power=line when they are above ground level and composed of bare conductors without insulation. Optionally, use layer=* 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 (provider, diameter, material and so on) between cable sections.
When mapped as such, ducts and support infrastructure hosting the cable can be deducted more easily from OSM data : power junctions may be made inside chambers while cables are going through ducts.
Cables - like power lines - can be member of route=power relations corresponding to a whole power circuit between two substations.

Location
| Key | Value | Comment |
|---|---|---|
| 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 | |
| undersea | A power cable located on the sea 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 forrests 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.

Services
As limited visibility features, cables are not rendered on the standard Mapnik 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.

- power=minor_line For small power lines supported on poles, in particular those having a voltage below 50 kV.
