Motors | KREMPEL

In medium and low-voltage motors, Krempel electrical insulation materials are part of our everyday lives although we may not be aware of them – whether in cars with combustion engines or alternative drive technology, in power tools, blinds or household appliances. And there are just a few examples – the list is in fact much longer.

Our multi-layered insulation materials, pressed paper, slot wedges, woven tapes and cords and other components are also essential for industrial applications such as traction, ventilation, industrial motors, forklifts, cranes, pumps and torques.

End-winding bracing

The perfect interaction of the individual components in the electric insulation systems forms the basis for the safety of electrical motors.

Thanks to our proven expertise and our strong reputation for quality and service, we enjoy long-term relationships in the field of energy and electrical engineering around the world.

One of our core competencies is to develop individual high-tech components for electric drives in close cooperation with our customers – such as our high-temperature solutions.

Automated manufacturing processes for inserting the windings go hand in hand with increased demands on the insulation materials used. In order to meet these requirements, Krempel insulation materials not only stand out for the outstanding electrical characteristics required, but also because of the following qualities:

High tensile strength
Flexibility and bending strength
High mechanical resilience
Ideal for folding and punching

Abrasion resistance
Flatness
High surface smoothness

Sheet pressboard, roll pressboard, kraft paper, corrugated board, pressboard with partial resin coating, mouldings, partial grid and full-surface pressboard mouldings.

FLEXIBLE MULTI-LAYER INSULATION MATERIALS

Technical laminates for motors and dry-type transformers with the very best electrical, mechanical and chemical properties.

Ripple springs

Electrically conductive side ripple springs and electrically insulating top ripple springs for high-voltage generators.

Kapton® films

Kapton® high-temperature films for extreme requirements. With excellent mechanical, thermal, electrical and chemical properties. Kapton® special films are further processed by us into laminates. As an authorised Kapton® dealer since 1989, Krempel has many years of experience, especially in individual applications.

Composite materials

Innovative materials, components and a comprehensive service provision.

Prepregs & UD-Prepregs

Prepregs from Krempel are semi-finished fibre products impregnated with reactive resins. Based on thermosetting resin systems, Krempel produces prepregs with all common fibre types, such as glass, carbon, basalt or aramid fibres. Natural fibres, nonwovens and papers as well as hybrid or combined structures round off the portfolio. These diverse possibilities make Krempel prepregs the ideal basis for lightweight and high-strength construction parts.
