SGB Czech Trafo history<\/h2><\/div>SGB Czech Trafo was established in 2016, when it followed on the production of dry-type distribution transformers using the Gravity Line technology, which was originally located in the Regensburg, Germany factory. SGB Czech Trafo thus continues to develop the long-standing experience in transformer manufacturing of its sister companies, SGB Regensburg and SMIT, which have been manufacturing transformers since 1947, respectively 1913 in the case of SMIT. Our factory, with a production area of 7,600 m2<\/sup>, is located in Olomouc, Czech Republic, and employs approximately 80 employees.<\/p>\n<\/div><\/div><\/div>![](\"data:image\/svg+xml,%3Csvg%20xmlns%3D%27http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%27%20width%3D%272560%27%20height%3D%271766%27%20viewBox%3D%270%200%202560%201766%27%3E%3Crect%20width%3D%272560%27%20height%3D%271766%27%20fill-opacity%3D%220%22%2F%3E%3C%2Fsvg%3E\" "\\"20180606_105523\\"")
