Transformers

R

Transformers are generally more cost effective than generators. On average, transformers cost 40-50% less to operate than generators and run 24 hours a day, maintenance free, naturally green, mostly without an operator, and are virtually twice as quiet!

R

Our transformer rental stock contains all sizes of transformers from small Buck/Boost-Standard step down units – specialty isolation shielded units – to large substation studio units. Almost all of our transformers come with primary and secondary switches, roll bar protection, and either dolly or skid/trailer mounted

An extensive list is provided under product specifications.  Call us if you don’t see what you need, please ask, as we’re constantly adding to our rental stock.
