Insulators are devices which protect a power line from grounding when connecting (suspension or anchorage) it to a building or a portal.
We also can find them hanging between two towers.
Power insulators can be tagged with power=insulator. Here is a non-exhaustive list of applicable situations:
- Portals : On large portals, it can be useful to use insulators to map the link between the power lines and the corresponding to the portal. It's mandatory to do so as for distinguishing suspension vs anchor on several lines linked to the same portal.
- Any man made structure : As mentioned on Talk with the Cologne Bridge example, insulators may be useful to link power lines to uncommon supports, like bridges arms.
Power insulators can be mapped with nodes or ways depending on their size or length. You may tag them as follow:
|power||insulator||It's a power insulator linking an overhead line to another (grounded) infrastructure||mandatory|
|operator||operator||The power insulator operator's name.||recommended|
|line_attachment||Line attachment||Means by which the line is bound to a support||optional|
|ref||Insulator reference||Power insulator reference as seen in situation||optional|
|height||height||The height of the insulator from the ground||optional|
|France||Support : Insulators are used to anchor the power line on a concrete portal
|France||Not a support : Insulators hanging between two massive power towers
|Germany||Support with insulator on a Cologne bridge|
