Submersible pit type transformers

These transformers can be installed in underground chambers or pits where there is flooding risk, as it has been foreseen that they may remain submerged in water. They are completely airtight, bathed in mineral oil, without conservator and have a dry nitrogen upper chamber to absorb oil expansion. The medium voltage external connection is made with plug-in connectors on-load operated, with control-rod. All the external surface of the machine has a bituminous-epoxy paint protection.


They are manufactured in accordance with IEC 76 and Complementary Standards.
