Royal SMIT develops, manufactures and installs transformers, phase shifters and reactors between 100 and 1,200 MVA and up to 765 kV.
More than 100 years of expertise and experience combined with the latest equipment provide an important basis for Royal SMIT‘s further optimisation of its production processes.
Royal SMIT tests its products in a laboratory setting with equipment which can be considered ”state of the art”
Royal SMIT uses air cushion transport for the internal movement of both individual components and complete units. The company has relationships with specialist international shipping companies for the transport to customers.
During installation the transformer is assembled and given a full oil treatment. Limited tests are carried out. Customers often carry out these activities with their own employees, but always under the supervision of an expert from Royal SMIT.
We have our own service department in the form of ”SMIT Transformer Service”, which provides repairs, preventative maintenance and service on Royal SMIT’s own transformers and those of other manufacturers.
STATE-OF-THE-ART TRANSFORMER DESIGN
Royal SMIT Transformers B.V. has an ongoing engineering evaluation process for continuous improvement and upgrade of its design programs. Royal SMIT engineering is making full use of a high end 3D-CAD system for the complete transformer design. Active parts and tanks can be combined in one model allowing the best possible check on correct dimensioning. The introduction of 3D-CAD technology was thoroughly prepared over the past years. A team of experts worked fulltime on the required tank- and active part models.
CLAMPING OF WINDINGS
The windings are clamped independently from the core, so no stresses are transferred to the core steel material, resulting in improved core losses in service.
SMIT STYLE WINDINGS
As there are no pressboard axial spacers present in the winding, there is less axial shrinkage of the windings, so that the winding clamping pressure is maintained throughout the life of the transformer, resulting in improved short-circuit withstand capabilities.
The tank design may be optimised in terms of cost and weight, reducing the overall shipping dimensions and weight.
The vibration levels on the tank surfaces can be greatly reduced, giving increased reliability in service.
