Driescher outdoor-switches in the 1- and 3-pole design are specifically designed for high supply reliability and comply with the specifications in accordance with EN 62271-102. The switches can be used for a rated voltage range of Ur 12 kV up to 38.5 kV depending on the design and for a rated current of Ir 400 A, 630 A and 1600 A. Switch design: For the vertical assembly (wall mounting), the disconnector with a switching angle of 90° is prefered. To ensure an independent closing in the horizontal mounting (pole mounting), switching angle of 110° is required on the actuating shaft. The disconnector blade set is directly actuated with the insulators by the actuating shaft. The baseframe as well as all steel parts are provided with a galvanized surface protection acc. to DIN EN ISO 1461 or stainless steel, which provides excellent corrosion resistance. The live parts are of electrolyte copper with elector silver plating in compliance with QTL 0200. For insulation to earth the insulators of cycloaliphatic cast resin are used, which has proved itself over the decades. For rated voltage of 12 kV and 24 kV, a pollution degree of PD 3 (25 mm / kV) and for 38,5 kV a pollution degree of PD 2 (20 mm / kV) is specified as standard. (Higher pollution degree on request.)
