cast resin transformer in outdoor enclosure (UK)
(OP)
I need to spec and buy a transformer to supply a new plant that we are putting in a remote corner of an existing site. All existing transformers on site are dry types, and site engineers prefer to keep this new one similar. I have looked at GRP enclosures (plus suitable IP rated enclosure around tx)as used by the UK utilities for unit substations, but these seem to use oil transformers inside (but curiously I can't see any oil bund on their foundation drawings). I guess utilities use oil transformers due to cost? None of the suppliers I've approached so far have been able to offer tx and enclosure. So, can a cast resin tx go in this type of enclosure? I've put them many times into rooms with louvred external walls, and this doesn't seem much different. Tx is 1600kVA, 11/0.433V. TIA, Brian

There are others who could offer this, as Scotty said. Also try Brush at Loughborough
As an aside, we are moving over to Midel (KNAN), midel is a flame resistant, biodegradable liquid.
We have nothing against cast resin units, only that you have no pre warning of failure.
