The space saver from Oerlikon: innovations in urban substations

The challenge 

A modern substation needed to be built in Zurich’s Oerlikon district that was not only aesthetically pleasing, but also space-saving and environmentally friendly. The existing design required a significant reduction in size in order to free up valuable building land and maximize capacity.

The solution 

PFISTERER has developed an innovative plug-in transformer connector that connects up to four cables in a vertical and highly compact way for the first time. This solution makes it possible to reduce the substation’s footprint by 70 %, making it a showpiece of modern urban industrial architecture.

Products used 

Plug-in CONNEX 4-way transformer connection part

Special features 

The new substation only requires 30% of the original space. The use of vertical connection technology enabled 5,200 m² of valuable building ground to be freed up. The space-saving encapsulation and the option of earthing accessories also allow work to be carried out without additional barrier screens, which further simplifies installation and optimizes the space.
