BETA 500KVA/11/0.415V COPPER/COPPER WINDING TRANSFORMER
Produced within a power range between 10 – 100.000 kVA , up to 170 kV high voltage level, three phase or single phase, oil immersed, ONAN, ONAF, OFWF, with Off-Load or On-Load Tap Changer, used both external and internal.
Dimensions of transformer conservator are determined and designed after several heat calculations of the oil stored in expansion tank and oil level changes by heat.
Being open to atmosphere, oil pressure changes continuously in Conservator Type Transformers due to thermal effects and exchange of air is dehumidified via air breather silicagel.
