In addition to producing special drives and electronic ballasts, we have specialised primarily in the manufacture of protection devices for liquid-cooled and liquid-insulated appliances. Our decades-long experience in the development and manufacture of Buchholz relays in particular has enabled us to carve out a reputation as one of the leading companies in the sector. Our highly-qualified workforce, as well as our modern manufacturing and inspection techniques, ensure a high standard of production, with quality and precision as our watchword.
