Translation:
The transformer in the mast are moved inside the new station.
(main reason safety for the workers)
Rating 100 kVA double Y primary 22kV secondary 230V adjustable +/- 2 steps of 2.5 %. No load loss: 325W.

http://moretrafo.no/The transformer supplies an existing IT network, New networks would have been TN-C to customer, (TN-CS from there) If dual voltages are needed they may use an extra set of windings, but prefer 2 transformers to keep the load more controlled. In that case the station will be slightly bigger.
They do not use high voltage expulsion fuse due to risk of fire in dry summers. They usually use a spring loaded fuse and switch, or a full-range fuse of a type not blowing out hot gases.
