xSolAir - Modular solar power station

xSolAir is Eaton’s high-performance plug-and-play packaging solution for solar power plant. The medium voltage switchgear, liquid immersed transformers and low voltage assemblies are all in one enclosure. The substation is completely pre-assembled, saving the customer valuable time. On site only the cables need to be plugged in, all the rest is already in place. xSolAir is using a standard seaworthy ISO container, making delivery and logistics much easier.

SF₆-free switchgear

Using vacuum technology instead of SF₆ not only makes Xiria the best for the environment, but also minimizes maintenance, enhances operational safety, greatly increases the number of safe switching operations, and eliminates costly end-of-life disposal procedures. Eaton campaigns for SF₆-free switchgear to protect our environment. !!!low carbon impact, write something about oil - transformers
