AegisEcoTec Ring Main Unit
Our new AegisEcoTec Ring Main Unit (RMU) offers the same outstanding performance and applications as our existing Aegis range of MV RMUs but with greatly improved environmental credentials. The AegisEcoTec uses synthetic air as the insulating medium, which means a global warming potential (GWP) of zero.
AegisEcoTec uses synthetic air bringing environmental advantages for medium voltage (MV) switchgear. For load break switching, a new architecture is necessary.
AegisEcoTec uses a small load break vacuum interrupter (VI) shunted across the main current-carrying contacts. This shunt VI breaks the load current, ensuring there is no arcing of the main current-carrying contacts.
The AegisEcoTec range is designed to be smaller and more efficient, while maintaining compatibility with standard installation requirements. As a result, the EcoTec range provides the same set of solutions for substations as conventional equivalents, but in a more compact and optimised package.
Across the AegisEcoTec range, operator safety is paramount with integral interlocking at the forefront of its innovative mechanism design. With a clear, unambiguous mimic and 100% padlockable human-machine interface (HMI), this solution is straightforward and secure.
To ensure the high industrial and operational reliability NZ’s networks need, AegisEcoTec 12kV RMUs use the same core mechanism design as the hugely successful Aegis RMU range which is installed worldwide.
