A transition substation sometimes referred to as transition yard. This is not a real substation but a fenced-off area with cable terminals where underground cables connect to an overhead power line. It comprises no active components such as switches or transformers.
How to map
See guidelines from power=substation or pipeline=substation to get more information.
A fenced perimeter should be installed around the substation. If the cable terminals are located on the power tower itself or if the pieline goes underground (no fenced area on the ground) don't tag this as a substation. Use the attribute location:transition=yes on the tower or the pipeline junction node instead.
