N. 61 Transformation cabins for the electrical grid

Description

The ambitious realization has the aim of increasing the electric grid in the Cuban capital.

The project has involved the carrying out and start-up of the following transformation centers with radial conjugation:

• Nr. 3 STC-Kiosk 24 13.8kV 100kVA nominal voltages on low-voltage side 220V
• Nr. 10 STC-Kiosk 24 13.8kV 150kVA nominal voltages on low-voltage side 480V
• Nr. 5 STC-Kiosk 36 34.5kV 150kVA nominal voltage on low-voltage side 480V
• Nr. 1 STC-Kiosk 24 13.8kV 500kVA nominal voltages on low-voltage side 220V
• Nr. 1 STC-Kiosk 24 13.8kV 500kVA nominal voltages on low-voltage side 415V
• Nr. 2 STC-Kiosk 24 13.8kV 400kVA nominal voltages on low-voltage side 220V
• Nr. 3 STC-Kiosk 24 13.8kV 400kVA nominal voltages on low-voltage side 480V
• Nr. 11 STC-Kiosk 36 13.8kV 500kVA nominal voltages on low-voltage side 220V
• Nr. 1 STC-Kiosk 36 34.5kV 750kVA nominal voltages on low-voltage side 415V
