The Lohr switchgear station is the main power supply for the Lohr am Main urban area and needs to be renewed and expanded to ensure the security of supply for the urban area and industrial companies. As part of the new construction of the medium-voltage switchgear, it is planned to replace the existing switchgear with a new SF6 gas-insulated double busbar switchgear. The challenge is to ensure a prompt and smooth process from the technical clarification to the commissioning of the switchgear in order to hand it over ready for operation as quickly as possible.

• New 20-bay medium-voltage switchgear NXPLUS C double busbar.  
• Back-to-back installation (duplex).  
• New SIPROTEC 5 (7SX85) protection technology. 
• Pressure diversion channel and therefore no pressure load on the building in the event of a fault and additional maximum personal safety for operating personnel.  
• Type approval 26th BImSchV, HS-TE test.  
• Parameterization and commissioning.

Expansion and renewal of the Lohr substation.
