Core offering

Ganz Electric manufactures custom-engineered high-voltage power transformers (40 to 600 MVA at up to 800 kV), medium and high-voltage electric motors (500 kW to 15 MW), synchronous power generators (1,000 kVA to 50 MVA), and synchronous condensers (15 to 60 MVAr). Every unit is individually designed, manufactured, and tested in-house at the Tápiószele facility, complemented by in-house steel structure production at Szolnok, ISO/IEC 17025 accredited testing, and the GANZ Intelligent Solutions asset monitoring platform.

Product overview

GANZ ELECTRIC offers a portfolio of individually engineered high-voltage electrical equipment complemented by a proprietary digital monitoring platform and comprehensive lifecycle services. The core product portfolio consists of four categories of heavy electromechanical machinery — Power Transformers (40–600 MVA, up to 800 kV), Electric Motors (500 kW–15 MW), Power Generators (1–50 MVA), and Synchronous Condensers (15–60 MVAr) — all manufactured, tested, and supported in-house. These are backed by a dedicated Test Bays & Laboratories division (ISO/IEC 17025 accredited) and an in-house Metal Works division for transformer steel structures. The GANZ Intelligent Solutions platform, launched in 2022, overlays the entire hardware portfolio — available as a factory-fitted option or as a retrofit for third-party assets — providing AI-driven asset monitoring, the Expert System for predictive fleet management, and Retrofit Digitalization for legacy units. Lifetime Services divisions cover transformers, rotating machines, and gas-insulated switchgears, offering maintenance, repair, refurbishment, and monitoring integration globally.
