1 GDS Pole Mounted Disconnectors Up to 52kV

2 General Information The switch for every application The GDS range is a modern switch system with components for different isolation and switching applications in overheadlines and substations. The system is characterised by a high degree of flexibility in order to meet different national standards as well as to meet various customer specifications. The base in the switch system is the phase element. To this component can different accessories be added for having the requested disconnector or switch specification. The switch can be installed in all different pole types, wood, concrete, steel poles or substation structures. Different insulator alternatives The GDS can be supplied with a wide range of different insulators in order to meet different isolation philosofies, enviromental conditions and different standards. The components of the switch system allow for different insulators to be used due to the design with parallel insulators without affecting the base and contact components. As standard can porcelain, outdoor epoxy resin and silicon rubber insulators be offerd. Beside the standard material can also insulators according to customer specifications be used. 2
