CSS is a type tested and arc tested assembly comprising an enclosure containing medium voltage (MV) switchgear, distribution transformers, low voltage (LV) switchboards, connections and auxiliary equipment to supply low voltage energy from medium voltage systems. These substations are typically installed in locations accessible to the public and ensure protection for all people according to specified service conditions.

Electrical House (eHouse), also called Power House, is a prefabricated walk-in modular outdoor enclosure to house a medium voltage (MV) and low voltage (LV) switchgear as well as auxiliary equipment. It can be skid or wheel mounted and is ready to operate in the field with minimum installation, commissioning and start up time – as an alternative to traditional on-site building construction (concrete block, brick construction or similar).

Primary and secondary skid unit for indoor and outdoor applications
Skid-mounted, prefabricated solutions provide permanent or temporary power for wide range of segments, including e-Mobility, renewables and data centers.
