Engineered for Oil-Immersed Transformer Applications

• Why It Performs Reliably in Oil-Filled Transformers

Polyvinyl Acetal coated flat aluminum wire is specifically suited for oil-immersed transformer environments due to its strong insulation characteristics and stable operational behavior.

Its performance is defined by dependable electrical insulation, consistent thermal stability, resistance to corrosion, enhanced dielectric strength, flexibility during processing, reduced skin effect, and chemical compatibility.

Performance Benefits

• Flexible & Easy to Process

The PVA coating allows the flat aluminum conductor to remain flexible, enabling smooth bending and precise winding during coil and transformer manufacturing.

• Enhanced Insulation Strength

The Polyvinyl Acetal layer improves dielectric strength, which is essential in high-voltage environments to minimize electrical breakdown and maintain insulation integrity.

• Strong Coating Adhesion

The insulation bonds securely to the aluminum surface, ensuring durable protection and long-term performance stability.

• Chemical Durability

PVA insulation resists chemical exposure, helping safeguard the conductor when it comes into contact with substances that could otherwise affect insulation quality.
