4 06 Skema s Modular Substations can be used for a wide variety of applications including LV/MV/HV packaged substations, local equipment rooms, control rooms, generator power plant rooms, personnel refuges and as general process or utility buildings. They are fully assembled and rigorously tested within Skema facilities before being shipped to site, by land, sea or air, ready for rapid installation and commissioning Local equipment room Fabrication yard Ravenna Italy
