The TRIDELTA Group Of Companies

The Tridelta group of companies with its two production sites in Hermsdorf and in Dortmund has its roots in three fields of special competence:

-technical ceramics
-sintering technology.

It was in Hermsdorf in 1890 that Tridelta Überspannungsableiter GmbH (resp. its predecessor company) was founded as the first member of the group. Based on the ceramic tradition of the Saale-Holzland County the production of porcelain insulators for electricity distribution was started . In 1961 the product range was enlarged by offering also surge arresters in porcelain (and later in silicon) housing; quickly arresters up to 420 kV were produced, followed later by arresters up to 800 kV system voltage.

Meanwhile, in the early 1950s, TRIDELTA GmbH, today the group’s parent company , had developed and commenced production of soft and hard ferrites, another area of ceramic manufacturing. Since that time the company has grown to become one of the biggest ferrite producers in Europe. The company mission of TRIDELTA GmbH is the speedy and cost-efficient development and production of innovative products and solutions for their customers. For this end TRIDELTA GmbH has its own R&D department, but also uses its close connections to technical universities and the Hermsdorf Institute Of Technical Ceramics.

In 1997 the group acquired Thyssen Magnettechnik GmbH in Dortmund as a way to widen its range of magnetic products. This company, which operates under the names of Tridelta Magnetsysteme GmbH and Tridelta Siperm GmbH, today looks back to more than 50 years of production and considers itself one of the most experienced providers of magnetic materials, components and magnetic systems as well as sintering products.

Tridelta Magnetsysteme GmbH on its part provides and produces special solutions for magnetic problems of their customers based on its profound knowledge “around magnetism”, while Tridelta Siperm GmbH offers specific products for their clients’ filtration-, fluidisation- and noise-reduction needs based on its long experience in the sintering of porous materials.

The recent award “Supplier of the year” by an internationally renowned company emphasizes the high professionalism of the group , its high quality and reliability standards as well as its clear customer focus.
