Technical FAQs 4

What is a containerized mobile substation?

Containerized mobile substations are sheltered and address applications in challenging environmental conditions including areas with high pollution, high humidity, extreme temperatures or sand storms. Containers are easy to transport and fast to install, by reducing foundation works as well as installation and commissioning effort on site.

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.

Can a circuit breaker be controlled from a substation?

Our system supports remote control of the entire circuit breaker within low voltage cabinets and ring network cabinets, as well as the ability to access operational information from substations.

What is a medium / low voltage step-up transformer?

Medium / low voltage step-up transformers The transformers inside our container solution can be designed to meet various global and industrial standards. For instance, they can be manufactured according to different loss levels, including Tier 2 as per the EU’s ecodesign regulations.
