Dogbone is a staple in transformer core winding, delivering the perfect combination of rigidity, insulation, and geometric uniformity needed for efficient, repeatable winding. Complementing the Dogbone profile, our broader family of duct-stick shapes—spacers, channels, rectangles, and more—helps manufacturers optimize core cooling paths, maintain alignment, and improve long-term transformer performance.
At GRT Genesis, we support your designs with high-capacity manufacturing and deep inventories across multiple standard and custom Dogbone and duct-stick profiles. Every profile is pultruded to demanding specifications and qualified for temperature classes up to Class H, ensuring dependable performance in even the most demanding electrical environments.
