Product catalog summary
Overview
The document outlines the electrical insulation materials provided by the KREMPEL-GROUP, focusing on their use in motors, generators, transformers, capacitors, and other electrical devices. It highlights the company's reputation for quality and innovation in the global electrical industry.

Insulation Materials and Applications
  • Presspaper and Pressboard: Utilized for insulation in motors and transformers, these materials are noted for their high breakdown voltage and oil impregnation capacity, standardized under IEC 60641, and capable of withstanding high heat loads.
  • Multi-layer Insulation Materials: Created by laminating plastic films with other materials, these insulations are tailored for specific temperature ranges and mechanical properties, used in various electrical applications such as slot and phase insulations.
  • Prepregs and Resin-bonded Materials: Employed in transformer and electrical machinery construction, these materials provide insulation and secure current-carrying parts, including banding tapes and sealing tapes for specific engineering tasks.

Product Specifications
  • High-voltage Machines: Products like KREMICA.flex mica tapes and TRIPREG-STABIL are used for conductor and turn insulation, while KREMICA.therm and KREMICA.por are used for main insulation.
  • Motors: Insulation materials are available for all thermal classes, with products like TRIVOLTON H and TRIVOLTHERM NKN designed for specific temperature ranges.
  • Transformers: The document details materials for both dry-type and oil-filled transformers, including PREPREG EVBD and KREMPEL-DPP for layer and winding insulation.

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 technologies....

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 insulating...
