Moisture Protection of Insulation Material
Transformer manufacturers are well aware of the effect humidity has on insulation material, whether it is made of cellulose or aramid fibers. Changes in the water content of the material leads to shrinkage and swelling respectively. During the winding process, winders have noticed deformation between the strips at the upper end of the vertically wound […]

Through simulations design configurations were validated. Simple, inexpensive and counterintuitive solutions can be found for complex problems. For all the details click here.
weiterlesenBTS@Weidmann – Rings
The world’s largest transformers demand the world’s largest components. At high voltages, especially in HVDC projects, the quality of components and adherence to strict tolerances is also essential. Weidmann manufacture the world’s largest Shield Rings at both European and American facilities. But how are these constructed? And how are such large components shipped safely and […]

"Save cost – buy quality" was a Weidmann slogan many years ago. Since then the cost pressure in the industry has increased dramatically; yet the slogan remains true to its word. Stakeholders in the transformer industry are under substantial cost pressure, which in turn is passed on to suppliers. Participants in the supply chain do their best to minimize costs and present an [...] weiterlesenCase Study III: Forces under double inrush condition
Through co-simulation (FEM and circuit system simulator), forces under inrush condition in complex configurations are computed; correcting measures can be put in action to prevent failures. For all the details click here.
weiterlesenTUF-Flex®
Developed to insulate low voltage windings in distribution transformers, TUF-Flex® is a thin paper that replaces thicker papers. It combines excellent mechanical strength with electrical characteristics and aging behavior. Using the highest quality raw materials, TUF-Flex® is manufactured following design processes that achieve the optimal electrical characteristics. The paper is produced on multi-ply machines that [...] weiterlesenAnd the winner is…..Weidmann!
Each year, the Croatian Association of Exporters organize the ‘Golden Key‘ gala event to highlight the achievements of Croatian companies and award the best exporters. The awards are a very prestigious affair, with the Prime Minister of Croatia and other cabinet members in attendance. We are proud to announce that this year Weidmann Izo-Prod was […]

Through simulation, tank hot spot areas are located, their formation is understood, effective solutions to prevent overheating are found and therefore the upgrading of the unit is possible. For all the details click here.
weiterlesenLaminated Transformerboard
Transformerboard is manufactured in accordance to IEC standards, in a single sheet and in a thickness of up to 8 mm. The thickness range can be extended up to 150 mm by laminating Transformerboard T4. In America and Europe Weidmann use liquid adhesives, usually polyester, however depending on the customer specification, may also use casein. […]
