You need customized transformer solutions?

Power and industrial transformers represent the top class of transformer technology. When transforming infrastructural currents, a high degree of reliability in the development and manufacture of transformers must be ensured. SIK Industries supplies transformers that meet the highest safety requirements and offer outstanding efficiency.

What the power supply unit does when charging household appliances such as laptops or mobile phones, our large transformers implement for entire industries: They transform voltages up or down by a multitude of your output voltage. In the process, they develop maximum voltages of several megavolts.

Let us realize your project together!

We are your contact for large components, machines and devices for all industrial applications, whether they are to be developed in stages or newly.

Transformers from SIK Industries can be used as mains transformers, matching and autotransformers or transformers for power converters.

Solutions for different
Fields of application

Ofentransformator mit extrem hohen Leistungsspitzen

Furnace transformers

A common use of converter transformers for industrial applications is to provide a reliable power supply for arc and graphite furnaces in heavy industry.

Power up to 200 MVA
In this area, the transformers are required to provide high performance up to overload. Our furnace transformers have an output of up to 200 MVA and offer good compensation for temporary overloads and load changes under the toughest conditions.

HGÜ Transformator für maximale Zuverlässigkeit

HVDC transformers

Transformers for high-voltage direct current transmission are also called HVDC transformers. They have a particularly high transition power between the primary and secondary side.

Highest reliability
The purpose of the transformation is to ensure low-loss transmission of the electricity in the high-voltage grid. Due to the grid supply function of this transformer type, SIK Industries develops the most reliable HVDC transmission transformers on the market.
