Single phase transformers
TEI Type
Single phase transformers from the TEI type are used on energy systems either as security - isolation type transformer or step up - down transformer, in machine control panels, automation panels and etc. Depending on such factors as the specific transformer type, number of windings, core type, output voltage, etc., AST Engineering can provide Single phase transformers for a wide range of requirements.
