Electrical Insulation

For safe and reliable electrical insulation. From energy generation through to consumption.

Electrical insulation materials are the key factor when it comes to the functionality and service life of generators, transformers, electric motors, energy storage systems and charging stations. We count all major companies in the global electrical industry amongst our customers and trust in the reliable quality of our electrical insulation materials and our intensive technical application advice.

For many decades, Krempel electrical insulation materials have been synonymous with safe and reliable insulation of generators, transformers, electric motors, energy storage systems and charging stations. The electrical insulation system is the key factor in ensuring perfect functionality and longevity. More precisely, it is the optimal interaction of the individual components. We take care of the fundamental matching of the insulation components for you and advise you on what is crucial for your specific application.
