The two volumes of "Oberleitungen für hochgespannten Einphasenwechselstrom in Deutschland, Österreich und der Schweiz" ("High Voltage AC OLE in Germany, Austria and Switzerland" by Georg Schwach were published in December 1989. For many years they have been out of print. Today, twenty years later, we have the pleasure to give access to text, drawings and photographs in PDF format on Internet.
