Transformerboards: high performance insulation boards for transformers

In a short circuit, extremely high mechanical forces occur inside a transformer, placing significant stress on the transformerboards. High compressive strength and density, as well as dimensional stability, are essential properties for reliably withstanding these loads and stabilizing the transformer’s internal structure. These properties can only be ensured through high quality manufacturing processes featuring high pressing forces, simultaneous closing of the heating platens and constant process parameters.

Above all, high system availability—achieved through optimized setup times, combined with automated and robust manufacturing processes—enables high output volumes. Consistently high product quality with minimal scrap also plays a key role. At DIEFFENBACHER, this is achieved through—among other factors—high and uniform pressing forces, rapid dewatering of the boards, and gentle material processing and simultaneous closing of the press.
