Prefabricated electrical substations (E-House)
The E-House concept (Electric Container/Shelter) defines a prefabricated Low Voltage (LV) and/or Medium Voltage (MV) Substation, carried out in compliance with the environmental requirements and the processes of the system it serves, designed and built to shelter and interconnect Panels and electrical equipment in various configurations and sizes.
Electroalfa produces a wide range of Medium Voltage/Low Voltage Shelter types and sizes, both in typical versions, as well as derived models, adapted to the required applications and to the site location. The dimension of the electrical substation (E-House) is in most cases constrained by the transport and handling conditions until the final destination. In compliance with the environmental and site safety conditions, the prefabricated substations could be built and delivered in a modular system, with the components assembled on site and fastened to the foundation by welding or threaded fasteners.
By their mobility and versatility, the prefabricated substations (Containers/Shelters) provide a competitive advantage in terms of logistics and work agenda, preserving the functionality, quality and operational safety of a typical electrical substation, directly built at the place of use.
The prefabricated substations (E-House) are employed in electricity distribution networks of the urban, rural, industrial areas, building sites, mining, oil platforms, agriculture etc. or in case of power plants operating with coal, gas and/or steam and renewable energy power plants.
The AlfaHouse metallic shelters can be executed in two versions with regard to envelope:
- AlfaHouse Compact – with walls of corrugated steel, continuously welded to the structural frame of the Shelter, covered with sandwich-type thermo-insulating metal panels;
- AlfaHouse Panel – walls made by sandwich-type thermo-insulating metal panels.
As regards the possibility of assembling several containers, Electroalfa can produce the two types described below:
