3AP1 DTC Dead Tank Compact - the versatile
For 145 kV and 245 kV applications
The hybrid concept on which the 3AP1 Dead Tank Com-pact (DTC) is based combines SF6-encapsulated components and air-insulated devices. The application of gas insulated components increases availability of the switch-gear. According to CIGRE analyses, gas-insulated components are four times more reliable than air insulated components. Furthermore, safety can be enhanced by separating gas compartments, e.g. between the circuit breaker and disconnector.
The DTC circuit breaker is a compact arrangement of several functions needed in a substation. The elements of this Siemens compact switchgear is a dead tank circuit breaker, fitted with one or two current transformers, one or more disconnectors, earthing switches and bushings as applicable for connection to the bus bar system. And of course, based on our modular design, the core components are adopted from our high-voltage circuit breakers, disconnectors and GIS product family. Due to the compact design and the flexible use of predefined modules, different layouts can be realized with a minimum of engineering effort.
The level of encapsulation and the design of the DTC module can be defined in accordance with the requirements of the individual substation layout and the system operator’s project budget. This leads to optimized investments and greater success for our customers’ businesses.
The 3AP1 DTC offers you:
l Proven SF6- and air-insulated components that can be combined in new and different ways
l Optimized investments according to the requirements of your individual substation layout
l Gas insulated components ensure the highest availability at minimum maintenance effort
l Flexibility in confined spaces and extreme environmental conditions, e.g. low temperature applications
