Description
Freely configurable
block versions
Besides the standard panel blocks, the fully modular switchgear concept offers
the possibility to combine freely configurable panel blocks.
Up to four modules can be combined in one panel block. The position of the individual
modules is free, except for the bus sectionalizer modules.
The width and weight of the switchgear results from the addition of the configured
individual panels.
Personal safety • Safe-to-touch and hermetically sealed primary enclosure
• HV HRC fuses and cable sealing ends are only accessible when outgoing feeders
are earthed
• Operation only possible when enclosure is closed
• Logical mechanical interlocking
• Capacitive voltage detecting system to verify safe isolation from supply and phase
coincidence
• Feeder earthing via make-proof earthing switches
Security of operation and
availability
• Sealed primary enclosure
• Independent of environmental effects such as pollution, humidity and small animals
• Sealed for life: Welded switchgear vessel, welded-in bushings and operating
mechanism
• Operating mechanism parts maintenance-free (IEC/EN 62 271-1/VDE 0671-1)
• Operating mechanisms of switching devices accessible outside the switchgear vessel
• Switchgear interlocking system with logical mechanical interlocks
• Mechanical position indicators integrated in the mimic diagram
