The insulation system of high-voltage machines consists of components that have to be optimally matched to each other. High-quality mica products are used as main and partial conductor insulation. Mica is a natural mineral with very good electrical insulation properties. It is primarily used in high-voltage applications.
The range of mica products manufactured by Krempel includes carrier materials such as glass fiber fabrics, high-temperature foils and non-woven fabrics that are impregnated and reinforced with synthetic resins. The resin-rich KREMICA.therm mica tapes are processed in the so-called resin-rich process (= hot pressing), the low-resin, porous KREMICA.por mica tapes in the VPI process (= vacuum pressure impregnation).
At Krempel, mica paper and mica shavings are processed on specially designed, state-of-the-art production facilities.
