Electrical Insulation
Insulation coatings are becoming increasingly important in modern machine and plant engineering.
Increasing performance requires thermally or electrically insulating functional coatings, which can be achieved with ceramic-based plasma or detonation coatings.
We produce high-performance insulation coatings for electrical insulation, which is used not only in electrical engineering but also in mechanical engineering.
Insulating shaft connections effectively prevent damage.
