Product Description

A Transformer core of Grain-Oriented Silicon Steel – The Core of Transformer Excellence

At the heart of every high-performance transformer lies a critical component: the core. And at the heart of core lies Grain-Oriented Silicon Steel (GO) —a material engineered for precision, efficiency, and reliability.

1. Unmatched Magnetic Orientation

2. Superior Energy Efficiency

3. High Magnetic Induction

4. Excellent Mechanical & Dimensional Consistency

5. Low Magnetostriction for Quiet Operation

6. Advanced Insulation Coatings

7. Tailored for Modern Applications

8. Sustainable & Future-Ready

By Insulation & Cooling Medium – Coating Compatibility, to define transformer cores

Oil‑Immersed

Most common for power and distribution. GO requires insulation coatings resistant to hot transformer oil (thermal stability up to 120°C+), high interlaminar resistance, and hydrolysis resistance.

Dry‑Type

Air‑cooled, used indoors or in fire‑sensitive areas. Coatings must withstand higher temperatures (class F/H insulation) and, for open environments, enhanced corrosion protection. Low‑loss GO maintains efficiency without liquid cooling.

Common Coating Need

Both benefit from insulation coatings that preserve low core loss after stress‑relief annealing.
