The most common application of power transformers to connect AC/DC networks of difference voltage levels to allow power exchange between the, while all specified requirements of each individual network. Rating capacity up to 132kV and 70-80MVA.
Two kinds of transformers are offered to fulfill these needs:
1- Interconnection Transformers:
It’s a galvanic insulation between primary and secondary networks and high adaptability to expected levels of performance and/or site conditions. We ensure you that the design and rating of tertiary windings, coupling and arrangements are fully adaptable to the client needs and request.
Compared with interconnection transformers of equivalent power flow, the autotransformer presents a lighter and more economically optimized solution which is possible when the voltage ration is between 1 and 2. The Autotransformers are needed to lower or increase the voltages used in transmission lines, and to interconnect systems that operate at different voltage classes.
