Types of GOES We Supply

 

1. Conventional Grain-Oriented (CGO)

Used in general-purpose transformers, offers balanced cost and performance.

2. High Permeability Grain-Oriented (HGO)

Improved magnetic induction and lower core loss, widely used in energy-efficient and low-noise transformers.

3. Laser-Scribed GOES (Hi-B / Ultra HGO)

Enhanced domain refinement for ultra-low loss applications; enables compact and efficient transformer design.

Processing & Surface Coating

GOES is supplied with insulation coatings suited for transformer manufacturing:

  • C-5 (Fully Insulated) – High resistance, heat-resistant coating

  • C-9 (Semi-Insulated) – Balance between insulation and weldability

  • Phosphate or Organic Coatings – For specific lamination bonding applications

We provide both un-slitted coils and ready-to-stack laminations.
