The EnergieBlock TEB-S can be used as a housing for transformer protection or in connection with a medium and / or Low voltage switchgear as (load substation stations).  The EnergieBlock is connected to the medium voltage, and the resistance to arc faults (IEC 62271-200) is thus achieved.  The EnergieBlock TEB-S is tested with 31.5 kA / 1 s. 

The removable housing comprises of a torsion-resistant cabinet system.  The rear and side elements can be replaced with doors or covers to allow for the subsequent installation of transformers or maintenance activities.  These doors and covers are designed to interlock, enabling the housing to achieve a high level of compressive strength.

These elements are equipped with ventilation gratings for venting the transformers.  This housing is designed for use in both AN and AF operation.  Either an extractor fan or a centrifugal fan will be installed for AF operation.

The necessary control elements for monitoring the transformer and controlling the airflow can be integrated into a recess in the low voltage installation.    

All parts installed are either galvanised, chrome-plated or powder-coated. 

The customer is able to select the top-coat paint from a selection of RAL colours.
