Schniewindt GmbH & Co. KG

We are the world market leader for braking resistors in electrical drive technology for medium voltage in the maritime sector.

Founded in 1829, the company has been producing electrical high-voltage resistors since 1902, making it one of the first suppliers of electrical equipment for power distribution. In 1964, Schniewindt supplied the first voltage divider for the world’s first high-voltage direct current transmission at the Cabora Bassa dam in South Africa. In 2003, the development of the first braking resistors for medium voltage for use in the maritime sector started, making Schniewindt the world market leader today. Since the foundation of a subsidiary in Shanghai, China, in 2009, Schniewindt has increasingly opened up the Asian market. Worldwide representations strengthen the international orientation of the family-owned company, whose business is managed by Dr. Sarah Schniewindt.

Schniewindt is one of the leading manufacturers of high-power electrical resistors and devices and systems for electrical heating technology for industrial and commercial purposes. This knowledge is also used to equip modern transport technology. On the one hand, heating systems for preheating diesel engines in marine and railroad technology and, on the other hand, braking resistors for electrical drive technology in the maritime as well as in the industrial sector are sold. As the world market leader for braking resistors in the use of DC systems on board offshore supply vessels, tugs, ferries and yachts, the company helps to reduce fuel consumption and emissions.

Of 200 employees, around 180 work at the Neuenrade site in the Sauerland region. The annual turnover is around €28 million, 42% of which comes from exports worldwide. Production takes place at the headquarters in Neuenrade and at the site in China for the Asian market.
