Tank integrity is essential for reliability and long transformer life. To ensure a perfect fit to the application, Makitel designs all transformer tanks to high internal standards taking customer specifications into account. Hot-rolled, low carbon steel plates are  cut to critical tolerances then joined via submerged arc welding to ensure against cracked seams and irregularities.

Engineering Process

Тhe production of transformer tanks takes place in a dedicated workshop area, equipped with CNC machines for precise cutting and shaping of steel sheets.

• Each tank is made from high‑quality steel, ensuring mechanical strength and complete oil tightness through advanced welding techniques.
• For efficient cooling of transformer oil, we use corrugated fins and radiators, which provide excellent heat dissipation.
• Every tank undergoes pressure and leak testing, including inspection of welds and surface finishing.
