Today’s papermaking process uses a lot of water and energy. Using foam as a carried fluid in papermaking process has two advantages: 1) the uniformity of the material is much more uniform compared to today’s technology, water-laid forming and 2) the solids content of material after the wet-press...

Cellulose is a common raw material in electrical insulation components. However, the production of high-quality products is labour-intensive and slow. Scientists are solving these problems by developing new processing solutions in the EU-funded Novum project. Significant improvements will also be ma...

Electrical insulation components are used in oil-cooled power and distribution transformers. The components are made to different three-dimensional shapes. The first step of the traditional way of producing these components is a common papermaking process. The resulting sheets are glued together and...

Power transformer is a key element of the power grid infrastructure and its reliability, safety and lifetime is strongly affected by the insulation system used, namely oil and cellulosic insulation. Cellulose is a common raw material for the insulation components due to its high purity, excellent di...

Within the NOVUM project, we have chosen to challenge ourselves across various disciplines in development of novel type of pilot line for manufacturing of electrical insulation components. Our raw material is cellulose, which is of course abundant, sustainable and already established in the end appl...
