This range of products covers standardized resin casted current and voltage transformers in block design up to 72 kV as well as cable current transformers. All products meet the specifications for various indoor and outdoor applications in power stations and power distribution systems.
Instrument transformers for low voltage applications are produced according national and international standards. The current and voltage transformers can be calibrated for different countries and delivered with the corresponding certificate.
We believe in Switzerland and Germany as locations that are centres of excellence for development and production, and the manufacturing facilities in Turkey and Brazil for the local markets. We are convinced that sincerity, innovation and performance are the building blocks for lasting success.
We take our responsibility as an employer and industrial enterprise seriously – our success is based on committed staff. We offer good working conditions and expect high levels of motivation from our employees. These features set us apart and form the basis of our partnership relationships with customers and suppliers.
