How Should a Transformer Be Transported and Handled?
Quick answer — Large transformers are transported with the tank either full or under vacuum/nitrogen, on a specialised transport frame or flatbed or barge, with impact and inclination recorders to detect rough handling. Shock, vibration, excessive tilt and humidity must be managed, and the unit inspected (and often the DGA/oil tested) on arrival before it is lifted into place.
What must be considered when transporting a large transformer?
Transport method
The unit travels by road, rail or barge depending on size, often on a special low-loader with a transport frame. Shipment may be oil-filled or with the tank under vacuum/nitrogen for very large units.
Monitoring
Impact and tilt recorders are fitted so any excessive shock or inclination is detected, and the unit must be kept within the manufacturer tilt and handling limits.
On arrival
Inspect for transit damage, oil leaks and moisture ingress; record the impact history; and perform insulation/DGA checks before installation and commissioning.
