MICAFIL, founded in 1918 and based in Zurich, Switzerland, established itself as technology leader in bushings through its manufacture of traditional types such as OIP (Oil Impregnated Paper) and RBP (Resin Bonded Paper) and insulation components.
1998 became a member of the ABB group. It developed the world’s first RIP bushings (Resin Impregnated Paper) in the 1960s, before producing the first 420 kV RIP bushings at the end of the 1980s and the first 550 kV RIP bushings in 1996. MICAFIL products helped ABB to expand its transformer bushings portfolio and to become the leading supplier of standardized and customized high voltage dry bushings.
ABB also offers a wide range of insulation components like laminates, fastenings and machined parts based on MICAFIL-competencies, well proven in demanding applications requiring dielectric, mechanical and thermal withstand capabilities.
