  2. 1. Cellulose-based electrical insulation materials : Dielectric and mechanical properties

    Author : Rebecca Hollertz; Lars Wågberg; Markus Biesalski; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose; dielectric materials; electrical insulation; nanocellulose; nanoparticles; streamer; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The reliability of the generation and distribution of electricity is highly dependent on electrical insulation and is essential for the prosperity of our society and a ubiquitous part of our everyday life. The present study shows how some important material properties affect the electrical properties of cellulose-based electrical insulation systems which are used together with mineral oil in high-voltage transformers.

    Abstract : Due to climate change and plastic pollution, there is an increasing demand for bio-based materials with similar properties to those of common plastics yet biodegradable. In this respect, cellulose is a strong candidate that is already being refined on a large industrial scale, but the properties differ significantly from those of common plastics in terms of shapeability and water-resilience.
