HSP and Trench Bushing Group
High voltage equipment and bushings
HSP Hochspannungsgeräte GmbH – known as HSP – has a long history and a well known reputation in manufacturing bushings and high voltage equipment. Over 120 years ago it was founded as a division of Meirowsky & Co., was then taken over by Dielektra AG and later by Felten &Guilleaume Energietechnik AG (F&G). Since 1989 HSP is an independent company. In 2007 HSP inaugurated the most advanced and technically developed factory and test hall for condenser bushings near Cologne, Germany.
