A corrugated transformer tank is a specially designed oil-filled transformer enclosure with corrugated steel walls that provide both:
Unlike traditional flat-wall transformer tanks, corrugated fin tanks use formed steel panels to improve cooling efficiency while reducing overall transformer size.
The corrugated structure allows transformer oil expansion and contraction caused by temperature changes, making it ideal for hermetically sealed transformers without conservators.
As an experienced transformer tank manufacturer, Radiastar provides complete production solutions from raw material preparation to finished tank assembly.
Transformer tanks are manufactured using premium low-carbon steel plates with excellent:
Common materials:
The corrugated panels are produced through precision hydraulic forming equipment.
Advantages:
Typical corrugation designs:
Radiastar uses advanced welding processes including:
