Electrically conductive materials
Flexible electrically conductive non-wovens and electrically conductive fabrics from KREMPEL are produced by impregnating non-woven or fabric materials with bonding agents containing electrically conductive particles. The concentration of these particles can be varied. Different types can also include zinc naphthenate as a catalyst. KREMPEL supplies rigid electrically conductive sheet materials for special applications as well.
Electrically conductive materials are used in high-voltage machines, high-voltage transformers and high-voltage cables in order to regulate the overall insulation, increase the reliability and to extend the service life. Depending on the application in question as banding material (KREMPEL electrically conductive non-wovens and electrically conductive fabrics) or slot filling materials (KREMPEL conductive sheets and glass fibre-reinforced plastic springs), these materials possess very specific mechanical, thermal and electrical properties.
