Technical FAQs 4

What is a containerized mobile substation?

Containerized mobile substations are sheltered and address applications in challenging environmental conditions including areas of high pollution, and humidity. Customers requiring shorter overall delivery times and minimal on-site work have been the main drivers for Hitachi Energy's development of pre-fabricated indoor substations.

How to energize a photovoltaic plant?

Using the fully pre-assembled and tested xSolAir substation, all it takes to energize a photovoltaic plant is to connect the medium voltage cables to the medium voltage switchgear. Covering every aspect of power management xEnergy Main low voltage system Xiria SF 6

What types of container solutions does Eaton offer?

Eaton offers several types of container solutions with metallic and concrete housing and full and semi-covered options. The first is a complete containerized solution that accommodates all the equipment inside, including the transformer, ring main unit and low voltage board. Benefits of the container design shown below:

What is an e-house substation?

E-houses substations are equipped with medium- and low-voltage equipment, AC-UPS and DC systems with batteries installed in a separate battery room. The integrated HVAC system maintain the indoor temperature even at -39°C and the split-systems are supporting peak cooling during summer.
