Current transformers of the TФУМ series

Current transformers of the TФУМ series

   Current transformers of the TFUM series are manufactured for a voltage of 330 kV.

External insulation of transformers - porcelain cover. The main internal insulation is oil-paper, capacitor type, located on the U-shaped primary winding. The number of secondary windings is four. The design is sealed.

  The series is characterized by reduced material consumption. The advantages of transformers are: a wide range of products in terms of rated primary current and accuracy class (0.2; 0.5; 0.2S; 0.5S; 5P; 10P); the ability to manufacture products with any combination of accuracy class and rated secondary load; high reliability and measurement accuracy.

  Our factory produces the following transformers: ТФУМ: ТФУМ 362 (ТФУМ 330А).

   Transformers are designed to transmit a signal of measuring information to devices for measurement, protection, automation, signaling and control in electrical circuits of alternating current with a frequency of 50 Hz or 60 Hz manufactured for supply within the country, to the CIS countries and for export to countries with a temperate climate.

   The plant uses software, computer-aided design and production preparation systems, which makes it possible to drastically reduce the production time of products and improve their quality.
