In-house products

Beside the production of electrical machines based on technical data from our customers, we can also offer self developed synchronous generators for power generation.

With its comprehensive vertical integration and state-of-the-art machinery PARTZSCH offers ideal conditions and realises the entire manufacturing of the machines. PARTZSCH provides customised solutions in the field of special machine engineering for power ranges up to 20,000 kVA and voltages not exceeding 15,000 V. We specialise in the manufacturing, maintenance, repair and commissioning of generators for the following applications: hydro power, steam turbines, frequency converters and marine and stationary applications.

Hydro power

Hydro power has a huge potential for power generation and is becoming an increasingly important source of energy. It is one of the major sources of renewable energy. Hydroelectric power plants can be controlled and easily adapted to meet the demand for electricity. For this application PARTZSCH delivers horizontal and vertical generators up to a power range of 20 MVA.

Steam turbines

Steam turbines play an essential role in combined heat and power, in steam power plants and in several industrial applications. Furthermore, steam turbines are deployed in the field of renewable energies for biomass applications, waste combustion and applications for solar thermal energy. For this application PARTZSCH delivers generators up to a power range of 18 MVA.

Frequency converters

Rotating frequency converters are used for increasing or decreasing the mains frequency in isolated operation. Furthermore, the output voltage can be adapted. Rotating frequency converters are often used in civil and military applications as ground power units. For this purpose PARTZSCH delivers frequency converters up to a power range of 5 MVA.

Marine and stationary applications

PARTZSCH also offers generators for power generation for the on-board power supply of civil and military vessels as well as generators for stationary applications (onshore and offshore). For this purpose, we cooperate with established classification societies.

For these applications PARTZSCH delivers generators up to a power range of 20 MVA.
