A corrugated transformer tank manufacturing process requires advanced fabrication technology, strict quality control, and precise engineering to ensure long-term reliability of oil-immersed transformers.
As a professional corrugated transformer tank manufacturer, Radiastar provides OEM transformer tank solutions for distribution transformers and power transformers, including hermetically sealed corrugated transformer tanks with high corrosion resistance, excellent oil sealing performance, and customized designs.
Our corrugated transformer tanks are widely used for:
Manufacturing range:
A corrugated transformer tank is an oil-filled transformer enclosure manufactured with specially formed corrugated steel walls.
Compared with traditional flat transformer tanks, corrugated tanks provide:
The corrugated wall works as both:
This design is especially suitable for hermetically sealed oil immersed transformers.
The complete manufacturing process includes:
Each production stage directly affects the service life and reliability of the transformer tank.
Before manufacturing begins, engineers review transformer specifications and customer requirements.
Important design parameters include:
Radiastar supports:
High-quality steel is essential for transformer tank durability.
| Material | Application |
|---|---|
| Q235B Carbon Steel | Standard transformer tanks |
| Q345B Steel | High-strength applications |
| Cold Rolled Steel | Corrugated fin panels |
Material selection depends on:
Before production, materials are checked for:
Only qualified materials enter the production process.
Steel plates are processed using precision cutting equipment.
Main processes:
Advantages:
Typical components:
The corrugated forming process is the key technology of a corrugated transformer tank.
Special forming equipment creates uniform corrugated structures on steel sheets.
Steel plates are positioned accurately inside forming equipment.
The machine applies controlled pressure to create:
The formed panels are checked for:
✔ Improved cooling efficiency
✔ Higher mechanical strength
✔ Better pressure resistance
✔ Longer transformer service life
After corrugated panels and tank components are prepared, welding is performed.

Benefits:
Inspection includes:
Transformer tanks must maintain complete oil sealing performance.
Checks:
Ensures the tank can withstand:
Verifies:
Before painting, transformer tanks undergo surface preparation.
Sand blasting grade: Sa2.5
The process removes:
Benefits:
A transformer tank normally operates outdoors for 20–30 years, so coating protection is critical.
