  1. ArcelorMittalTechnotron s.r.o. Cores of magnetic circuits – transformer cores 2008 Confidential

  2. Production range: ArcelorMittal Technotron s.r.o. • Wound transformer cores: • Toroidal cores • Cut cores • Unicores • Laminations

  3. Transmission transformers. Instrument transformers. Measurement transformers. Voltage transformers. Current transformers. Supply transformers. Power transformers. Low loss applications. Inductors. Converter. Suppression technology Regulatingtransformers. Pulsetransformers. Specialtransformers. Rectangularcurrent transformers. Transformers up to approximately 10 MVA. Single-phase and tree phase distribution transformers. Single-phaseand three phase chokes. ArcelorMittal Technotron s.r.o. Application possibilities

  4. Benefits: Closed flux path Low magnetic leakage Low noisiness of transformers Compact dimensions Low weight of transformers Type ofToroidal Cores: With chamfered edges With air gap Special shapes With protective coating ArcelorMittal Technotron s.r.o. Toroidal Cores

  5. Benefits: Electrical energy savings Low humming Saving in quantity of used copper for winding Saving in work costs exert for transformers assembly Cut surfaces of there cores can be round, oval and rectangular ArcelorMittal Technotron s.r.o. Cut cores

  6. Cut C cores single-phase According the DIN 41309 norm – SG, SU, SE, SM According to he IEC 329 norm – Q, R, M, U According to the ArcelorMittal Technotron internal norm - C Cut C cores three-phase According to the DIN 41309 norm – S3U According to the IEC 329 norm – 3U ArcelorMittal Technotron s.r.o. Cut Cores

  7. Benefits: Electrical energy saving. Saving in quantity of used copper for winding. Saving in work costs exert for transformers assembly. Low humming. Better use of coils scope. Easier windingof wire on a circular coil. ArcelorMittal Technotron s.r.o. CruciformCores

  8. UNICORE advanced technology leads to low specific losses Benefits of Unicore: Low specificlosses Easy assembly Favorableprice Saving in quantity of used copper The banding of cores is not necessary Short deliverytime Uncut Unicore Due to advantages oftheir construction Uncut Unicore are apt to replace almost allconventional uncut C cores andrectangular toroidal cores. Cornerangle can be 45 of 90 degrees. Application possibilities: Rectangular currenttransformers. Voltage transformers. ArcelorMittal Technotron s.r.o. Unicore

  9. ArcelorMittal Technotron s.r.o. Uncut Unicore

  10. Application possibilities: Single-phase transformers. Three-phase transformers. Power transformers. Current transformers. Measuring transformers. Instrument transformers. Transmission transformers Regulating transformers. Types of construction ArcelorMittal Technotron s.r.o. Duo Unicore

  11. ArcelorMittal Technotron s.r.o. Butt Unicore Is a core suitable for chokes; its front surface is superposed thus enabling conventional C core replacement. Application: single-phase chokes three-phase

  12. ArcelorMittal Technotron s.r.o. Step Butt Unicore • The air gap is designed as steps. Step butt Unicores can be annealed to reduce loss and make assembly easier. • Benefits: • Lower core losses than comparable C cores. • Higher transformer output. • Lower transformer weight.

  13. Belongs to the group of STEP BUTT Unicore. The gaps are on the opposite sides of the core. So the gap is on every other packet in the one leg. Thanks to this we can achieve reduction of losses and noise. ArcelorMittal Technotron s.r.o. Combi Step Butt Unicore

  14. DGAP core Application: Low loss applications Transformers up to approximately 10 MVA Benefits: The lowest core losses Higher transformer output Lower transformer weight Saving in quantity of used copper ArcelorMittal Technotron s.r.o. DGAP core

  15. All above mentioned types of UNICORE we are capable to manufacture in cruicy form. This means you can get all advantages of UNICORE even if your transformers are made of cruicy form C-cores. ArcelorMittal Technotron s.r.o. Cruicy form Unicore

  16. ArcelorMittal Technotron s.r.o. Manufacturing capacities: • Toroidal cores 40 t/month • C-cores 60 t/month • Unicores 20 t/month
