Design Parameters

The transformer substations are to remain unchanged in their technically optimized form. A cladding system is proposed that will be used for both existing and future transformer substations.

Surface Design

Starting with a mirrored stainless steel sheet, a CNC-controlled perforated metal milling process is carried out according to a predefined motif. Historical images of the installation site can be obtained from the city archives, for example. In the next step, the sheet is folded to resemble the cooling fins of the transformer inside and twisted in the rhythm of a sine wave of the alternating current.

The desired effect is the combination of the historical motif (perforated metal) and the reflection of the current surroundings in the mirrored points. As one walks past, a diverse and ever-changing image emerges, a blend of the historical view of the site (motif in the perforated metal) and the current surroundings (reflection in the polished points). At the same time, the mirrored surface dematerializes the transformer station, allowing it to blend into its surroundings.

The fanned and perforated surface is designed to make the transformer stations less attractive to graffiti.

Green Roof

A second cover, incorporating extensive greening, is placed on top of the existing concrete cover and can also be removed if necessary. The greenery provides an attractive view from above and can contribute to improving the urban climate.

Practical Installation

The substructure is mounted directly to the concrete walls of the transformer stations using brackets. Both the fixed sheet metal elements and the hinged, openable sheet metal elements are attached to these brackets. The green roof can be lifted off; eyelets for the necessary crane hooks are already integrated into the tubular frame.
