For over two decades, MGM Transformer Company has been a reliable source for quality secondary unit substation transformers. Our standard designs cover the full range of requirements from 5kV to 34.5kV, 500kVA to 10,000kVA, in both liquid and dry type. As an engineering oriented transformer company, we maintain a large engineering staff. Our experience in working with various switchgear manufacturers enables us to design the high voltagelow voltage switchgear interface, assuring the proper match in the field. Flex connectors can be supplied. Non-standard substation designs are also available for special situations such as failed unit retrofitting or PCB replacement. All manufacturing processes are done on the premises.This advantage, along with
a large inventory of electrical steel and wire, assures our customers of the industry’s shortest standard lead times, regardless of the interface
requirements.
