Elektrolites power offers disconnectors, which serve for mechanical isolation of systems and also act as safety devices. In the open position they provide a visible isolating distance. These disconnectors are able to open or close a circuit if either a negligible current is switched or if no significant change occurs in the voltage between the terminals of the poles. These disconnectors are applicable in many of the usual switchyard layouts of high -voltage outdoor application. For earthing and short circuiting of switched out options of the installation, the incorporation of one or two earthing switches are possible on each disconnector. The advantages of these disconnectors are that they need very less maintenance and they are insensitive to extreme external influences like earthquakes, short circuits, storms, etc.
