Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If power capacity exceeds 100 kVA up to 650 kVA
Higher kVA rating shifts to next capacity subheading in liquid dielectric transformers.
If uses dry-type insulation instead of liquid
Dry-type transformers fall under separate subheading regardless of kVA capacity.
If imported as incomplete assembly without full tank
Parts of transformers are classified separately from complete units.
