If well designed/manufactured, and if used within their ratings and in sensible environmental conditions, there's really no reason why a wire-wound transformer cannot last 'for ever'.
I have several power supplies, still working fine, which I build in the 60s using 'war surplus' transformers (of which there was then a plethora!) - hence now presumably at least 70 years old.
Kind Regards, John
