Furnace Transformers

Supplying arc melting furnaces places high demands on transformers: The windings must be sufficiently strong because they are exposed to a high degree of dynamic short circuit current forces and a large control broad regulating range is required. No problem for SGB!

• We have the necessary know-how and many years of experience in the design and construction of furnace transformers for ratings up to 80 MVA.

• Rated currents of up to 70 kA are not a problem.

• SGB furnace transformers can be constructed weighing up to 120 t.

Coupling units for audio-frequency remote control systems

Audio-frequency remote control systems are reliable and proven solutions for the remote control of devices in supply networks. We can supply coupling units for the serial and parallel supply of audio-frequency remote control systems in 110 kV and 20 kV supply systems.

Transformers with in-phase regulation and regulation in quadrature

System management often requires the interconnection of medium-voltage systems that are supplied from different high-voltage systems. In such cases, voltage that can be regulated in direct-axial and quadrature-axis components must also be generated at the interface. This problem is solved by our transformers with in-phase regulation and regulation in quadrature.
