The Role of Core Material in Transformer Efficiency
A transformer's energy efficiency is largely determined by its core material. The core directs the magnetic field and directly impacts energy losses. A standard core type transformer uses grain-oriented silicon steel. While effective, this material has inherent hysteresis and eddy current losses.
An amorphous metal transformer provides a high-efficiency alternative. The amorphous alloy has a non-crystalline structure that significantly reduces no-load losses, often by 70% or more compared to silicon steel. This feature results in lower lifetime operating costs. For specialized applications, we design custom power transformers to meet specific client requirements. Our engineers can develop a high voltage power transformer using either core material, depending on the project's performance targets and budget.
