Request written termsCheck this transformer against your project
Compare the complete winding arrangement and condition evidence before requesting a quote. A matching voltage ratio alone does not establish suitability.
- Compare 138/34.5 kV transformers
- Match MVA, voltage, impedance, taps and winding connections
- Review seven transformer condition risks before purchase
