Compact circuit breaker 3AP1 DTC

air-insulatedSF6 gas-insulateddead-tank

The 3AP Dead Tank Compact (DTC) switchgear for 145 kV and 245 kV applications is a compact arrangement of several functions needed in a substation. The hybrid concept combines SF6-encapsulated components and air-insulated components. It is possible to arrange the components in a variety of ways depending on your substation configuration. Flexible solutions according to your substation configuration - CB with single- or three-pole operating mechanism - Disconnector, earthing switch, high-speed earthing switch - Current transformer, voltage transformer and voltage detection system - Cable connections possible at various positions - Bushings available as porcelain or composite insulators - Additional separation of gas compartment, with SF6 density monitor on request - Double breaker modules for ultra-compact substation designs - Possibility for stand-alone components, e.g. disconnector module with VT - Flexibility in confined spaces and extreme environmental conditions - GIS components ensure the highest availability and safety at minimum maintenance effort - Optimized investments acc. to individual substation requirements - Minimum design work for various applications thanks to predefined modules
