Three Phase Distrubution Class Transformers

B & B Transformer builds 3 phase oil-filled distribution class transformers. We build sizes from 30KVA up to 2500KVA. We can build to any specification, voltage and any configuration.  We build to our customers specs, ANSI specs and 2016 D.O.E. specs. We can fabricate any type of unit you are looking for. 

One of B & B Transformer's foremost strengths is that we can build units very fast. We are small enough where we can move our production schedule around to meet our customers needs. In emergency cases, we have been know to make 3 phase transformers in a week or less.  We offer a full 3 year warranty.
