We provide specialized manufacturing solutions for hermetic oil-filled tanks used in high-voltage instrument transformers, based on precision welding, high sealing performance, dimensional accuracy, and long service life.

In transformer tanks, process safety and product quality are directly related to welding quality, surface preparation, flange precision, and sealing performance. Accordingly, we plan and carry out our manufacturing processes in line with the requirements of OEM projects with high quality expectations.

Our manufacturing capabilities include:

• Large-diameter tank manufacturing,

• Deep-drawn or dished cover and bottom applications,

• Thick flange machining and precision connection surfaces,

• Welded fabrication in accordance with dimensional tolerances,

• Leak-tight design suitable for hermetic construction requirements,

• Manufacturing suitable for helium leak test infrastructure,

• Project-based quality control and traceability processes.

With the manufacturing experience gained through long-term OEM projects, we develop tank solutions that meet the precision, repeatable quality, and reliable sealing performance required for high-voltage equipment.
