Transformers

Energetic transformer reparation and maintenance program includes all types of dry transformers powered by 1600 kVA of standard performances and voltage level up to 20 kV.

Energetic transformer with power of 4000 kVA and voltage level of 35 kV on servicing, filtering and diag­nostic of transformer oil dielectricity.

This program also covers all types of oil transformers with power of 16000 kVA and voltage level up to 110 kV.

Rewinding of energetic transformers for electrical locomotives with power of 5060 kVA and voltage level of 25 kV
Rewinding of energetic transformer on diesel - electrical locomotive with replacement and testing of transformer oil dielectricit

Apart from general reparation of energetic transformer, filtering, drying and testing of transformer oil is also included.

Machine with filtering capacity of 200 liters per hour is being used for oil filter­ing, and testing of it's dielectricity is being performed by testing machine.
