OUR BUSINESS: electrical insulation products

For more than 70 years, we design and develop, design and produce and offer a complete range of our electrical insulation products for dielectric insulators intended for a clientele of motor manufacturers, transformer manufacturers, automotive equipment suppliers (alternators, electronic modules ..), winders, and other manufacturers of electrical components.

With a perfect control of the whole production line, we have a solid experience both on flexible insulators, and on liquid insulators, and on the fertility between the two, with our liquid insulators applied on our flexible insulators.

We supply our electrical insulation products to the largest players in the energy, rail and automotive equipment industries. We adapt our production to adapt to the demands of the largest groups, such as those of very small businesses or SMEs.

To complete our range of insulators, we also offer our range of products and materials for the repair of electric motors.
