Carte has a comprehensive product offering of three phase network transformers.  Carte is able to engineer-to-order unique transformers that meet demanding technical requirements.  Our products comply with IEEE and CSA transformer standards and are available in oil and FR3 filled options.



NetInstallOur network transformer typically include a primary network grounding switch (3 position or 2 position) and a range of switch interlock options are available.  A wide range of features and options are possible, including special gauges, network without grounding switches, sidewall mounted bushings and switches, dual voltage ratings, phasing tubes, and many more items.


All of our networks are made with thick gauge copper bearing steel. This includes the cooling panels.  Stainless steel tank options (304L or 316L) are common among network users with particularly wet vaults in corrosive environments and Carte is easily able to meet this tank steel requirement.
