Best insulated by KREMPEL-GROUP Proven across the world Electrical insulation materials from the KREMPEL-GROUP have been used for many decades to solve insulation problems in motors, generators, transformers, capacitors and other electrical devices. All the leading companies in the global electrical industry are our customers and place their trust in our reliable quality and intensive application-based consulting competence. Everything for high-voltage machines Conductor and turn insulation: Main insulation: KREMICA.flex mica tapes KREMICA.therm Mica tapes for Resin-Rich technique...

Because the insulation system is the decisive factor for the functional capability and durability of electrical machines and devices, many electro-technical developments only became feasible thanks to our products. The KREMPEL-GROUP has lots of solutions from one source for this central electrotechnical problem in its extensive insulation materials range: from power generation to consumption. Everything for motors in all thermal classes Slot insulations, phase insulations, slot closures: KREMPEL presspaper KREMPEL multi-layer insulation materials for thermal classes 130 to ≥ 200 TRIVOLTON H...

Safety from the power generation to consumption Innovative, creative, service-intensive When developing future-oriented electrical machines and systems, particularly high demands are made of the electrical insulation materials. Because top quality products can only be realised using first-rate insulation materials that can cope easily with higher loads. The KREMPEL-GROUP has a broad production program in which special attention is also paid to subsidiary fields of electrical engineering that are often decisive for the functional security. Everything for dry-type transformers Layer and...

During the course of the intensive application-specific consulting, the insulation material experts of the KREMPELGROUP work together with the customer to find the best technical and economic solution. We will tell you what is important when selecting and using insulation materials. Many design problems can often be solved by modifying existing products or by developing new, tailor-made materials. Insulation materials from the KREMPEL-GROUP guarantee easy processing, a high level of functional security and best long-term durability. Everything for oil-filled transformers Layer and winding...

Presspaper and Pressboard Presspaper, pressboard, corrugated board Diamond dotted presspaper Ladders, ladder grids, ladder ducts Crepe paper tubes Presspaper and pressboard are proven insulation materials on a cellulose basis for the thermal class 105. Depending on the type of cellulose, fibre conditioning and machinery settings, the KREMPEL-GROUP supplies a variety of presspaper and pressboard types with very specific characteristics. These highly pure cellulose products are produced on special paper machines; we have one of the largest production systems for the continuous production of...

Multi-layer insulation materials Flexible multi-layer insulation materials Special multi-layer insulation materials Special films Flexible multi-layer insulation materials from the KREMPELGROUP are produced by laminating plastic films with presspaper, non-wovens, fabrics or plastic paper materials. The decisive know-how is contained both in the special lamination systems and also in the adhesive formulations that have been developed by our own technicians. Special lamination systems Multi-layer insulations are normally produced as three-layer combinations whereby the plastic film is in the...

Prepregs and resin-bonded insulation materials Prepregs Banding tapes & sealing tapes Insulation materials with cured resins KREMPEL-GROUP prepregs are produced by impregnating or coating a broad range of insulation materials with various resins which are still in the reactive B-stage. This means it is possible to attach the impregnation substance (resin) into the slots of electrical machines or windings of transformers at the same time as the insulation. There is no need for the complex impregnation process. Prepreg production Prepregs are produced at the KREMPEL-GROUP using a variety of...

Fibre-reinforced plastic profiles and components Pultruded plastic profiles Plastic sheets and moulded parts Injection mouldings Fibre-reinforced plastics have properties and application capabilities that conventional materials cannot offer. We have innovative products. We have complex production systems. We have extensive engineering competence in the fields of fibres, resins and processing technologies. And of course, we also help our customers design their fibre-composite components. Pultrusion production WACOSIT® plastic profiles can also be used in a variety of ways in electrical...

Mica and high-voltage products Mica tapes Electrically conductive materials Fibre-reinforced slot springs The insulation system for high-voltage machines comprises several components that need to be ideally matched to each other. Top quality mica products are used for the main insulation and conductor insulation. However, electrically conductive materials are required to control the whole insulation as these ensure safe potential equalisation. Finally, top ripple springs and conductive side ripple springs are required to fasten the rods. Mica products production Mica is a high-grade mineral...

Insulation sleevings and textile products Insulation sleevings Woven tapes Cords The KREMPEL-GROUP has a large pool of textile machines to weave, braid and knit woven tapes, insulation sleevings and cords. These textile products are required for electrical machines and transformers. Textile products production VIDAFLEX insulation sleevings can either be extruded from silicone elastomer compounds or braided/knitted using glass or polyester yarns. The fibre-based sleevings are then impregnated/coated with silicone, acrylic or polyurethane resins. Excellent protection against electrical,...
