Used Koopmann Transformatoren for sale (14)

Condition: as good as new (ex-display), We have our own extensive stock of approx. 210 oil and cast resin transformers in a wide range of power and voltage ranges, some of which can be made available immediately or with very short delivery times. These devices can be called up via our online database with individually printable data sheets. The database has an internal search function and is updated on a daily basis. Thanks to our close contacts with various transformer manufacturers, we can also offer you new transformers at optimized prices and delivery times. Furthermore, as former employees of the TRO Berlin (Oberschöneweide transformer factory), we deal with the overhaul and repair of oil transformers in the power range from 50 kVA to 63000 kVA, at a voltage level between 6 kV and 110 kV. We also offer our customers the conversion of transformers from Dehner design to hermetic design. In this context, the complete transformer is overhauled, i.e: - Drying of the active part and the transformer oil, - New paint structure of the boiler, Dksdpfx As A H U Ued Nsl - new tensioning of the active part, - conversion to Elastimold plug-in bushings on request, - Renewal of all seals, - Final test (winding resistances, ratio measurement and insulation resistances) in our own electrical test bay, including voltage run
