ABB TX 75 MVA Oil-Immersed Power Transformer
This liquid dielectric transformer from ABB has a power handling capacity of 75,000 kVA, used for stepping up voltage in utility substations. It falls under HTS 8504.23.0045 because it exceeds 59,999 kVA but not 100,000 kVA and uses oil as the dielectric medium. Designed for high-voltage transmission networks with robust cooling systems.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If power handling capacity is 40,000-59,999 kVA
Lower kVA range falls under the previous power capacity subheading within liquid dielectric transformers.
If capacity exceeds 100,000 kVA
Higher power handling moves to the next capacity bracket in the same liquid dielectric category.
If dry-type construction instead of liquid dielectric
Dry-type transformers use air cooling without liquid dielectric, classified under different subheading 8504.32.

Import Tips & Compliance
• Obtain IEEE/ANSI certification and test reports verifying power rating and dielectric fluid specifications to meet U.S. utility standards
• Ensure DOT compliance for oil-filled transformers including spill containment plans and proper hazardous material labeling
• Avoid misclassification by confirming exact kVA capacity via nameplate data; over 100,000 kVA shifts to 8504.23.0049
