Transformatorenhaus, Technology museum in Lohr am Main, Germany
The Transformatorenhaus is a technology museum in Lohr am Main housed in a former electrical transformer station from the early 20th century. It displays over 6,000 insulators across two floors, documenting the history of power transmission infrastructure.
The building was constructed in 1920 as a transformer station and converted to a museum in 2004 to document the evolution of electrical infrastructure. This repurposing preserved the original structure and made its technical history publicly accessible.
The collection displays porcelain and glass insulators from many countries, showing how power transmission evolved throughout the 20th century. Visitors see handcrafted pieces alongside modern industrial products and understand the practical demands of this hidden infrastructure.
The museum has limited opening times and typically requires advance notice for visits. It helps to check opening days ahead and contact directly if interested in visiting.
The collection ranges from tiny insulators for fences to massive units for high-voltage lines reaching 380 kV. These size differences reveal the varying demands of low to high voltage systems within a single collection.
