PREIS has many years of experience as producer of transformer tanks for power transformers. The product range covers small radiator units through medium voltage transformers to the biggest and most complex power transformers like HVDC-systems.
In addition to standard steel tanks, we have gained many years of experience in the production of special projects such as “Brückenmittelstücke” – compact high-power transformers for semi-autonomous rail transport, phase-shifters and, more recently, transformers for off-shore applications.
To complete the package, we offer our customers a range of extra services such as preparation of production documentation, identification of cost-reduction potentials and technical expertise in areas such as welding and corrosion protection according to ISO 12944 standards.
