Amorphous Low-Loss Transformers

Achieve 3% energy savings compared to traditional transformers

Maximise efficiency, minimise energy losses

With 70-80% lower core losses than standard transformers, modern amorphous cores offer unbeatable energy efficiency and carbon reduction. Priced similarly to CRGO (Cold-Rolled Grain Oriented Steel), they are a clear and cost-effective choice when looking to upgrade your ageing fleet or enable electrification upgrades.

Why upgrade from CRGO?

For decades, transformer cores have been made from CRGO steel. While reliable, these cores are less efficient – they consume energy even when the transformer isn’t supplying power, resulting in high no-load losses. Amorphous Steel is a modern alternative that offers lower core losses, especially when machinery is in low load or idle. Our Low-Loss Amorphous transformers are ideal for renewable energy integration, energy-efficient buildings and smart grid deployments, helping to maximise energy efficiency while reducing environmental impact.
