Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If rated exactly 50-650 kVA
Precise kVA capacity determines specific liquid dielectric subheading.
If as replacement cores only
Cores without tank or bushings are transformer parts.
If dry-type with >1 kVA capacity
Dry insulation shifts entire classification regardless of size.
