Manufacturing & Quality Standards (AS/NZS, IEC)

At Circle C Transformers, quality is not just a goal — it’s the foundation of our reputation. Every transformer we produce is built under strict manufacturing and testing procedures that meet and often exceed Australian (AS/NZS) and International (IEC) standards.

Our production process follows a disciplined approach — from the careful selection of raw materials to advanced winding, vacuum drying, impregnation, and precision assembly. Each stage is monitored by qualified engineers to ensure consistency, safety, and superior electrical performance.

Before leaving our facility, every unit undergoes comprehensive routine and type testing, including insulation resistance, ratio, polarity, temperature rise, and high-voltage withstand tests. These procedures guarantee reliability even in the most demanding industrial and environmental conditions.

Circle C is committed to continuous improvement and quality assurance, supported by detailed documentation, calibration systems, and inspection protocols. This dedication ensures that every transformer we deliver provides long service life, minimal maintenance, and unwavering performance — true to the highest industry standards.
