Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If downsized versions under 10MVA
Liquid dielectric transformers split by power threshold at 10,000 kVA.
If core and coil shipped separately from tank
Incomplete assemblies without bushings or liquid system classify as parts.
If precision rectifier transformers for industrial rectifiers
Transformers designed primarily for DC rectifier service have separate classification.

Import Tips & Compliance
• Provide IEEE C57.12.00 compliance certification; US utilities require ANSI standards
• Oil samples must meet ASTM D3487 Type II specifications; declare PCB-free status explicitly
• Coordinate port crane capacity (typically 500+ ton lift) and route permits for oversized loads
