Description: Contract notice – Sector Directive, standard regulation negotiated procedure with prior publication of a call for competition/negotiated procedure (construction work) Uw Berliner Straße Project description substation Berliner Straße The structure is being built on a 2,095 m² plot of land and is structured as follows: The cables are introduced into the building in the basement. From there, they are led directly into the 20 kV switchgear on the ground floor and via an open shaft into the 110 kV switchgear on the first floor. The two 110 kV transformers provided are arranged on the ground floor, while the oil drip pans for these transformers are located in the first basement. The building has a staircase in the southern area that provides access from the basement to the roof. A freight elevator will also be installed that reaches up to the first floor. The structure extends over a depth of approx. 22.5 m and a width of approx. 48.8 m. On the southwest side, a shaft approx. 2 m wide is planned, which serves the forced cooling of the two 50/63 mva transformers. The total building height is approx. 15.3 m including a parapet of 1.4 m. The civil engineering includes a well foundation for the foundation and the construction of a Berlin shoring with rear anchoring to secure the excavation pit. Furthermore, the building must be provided with a predefined expanded metal facade with corresponding substructure all around. The 110 kV switchgear on the first floor is to be designed as a gas-insulated double busbar variant with an alternative gas to SF6 that meets the current requirements of the F-gas regulation. This switchgear comprises seven panels with the following division: transformer 1, feed-in network 1, longitudinal separation, cross-coupling, feed-in network 2, transformer 2 and reserve panel. The busbars and panels are to be designed for 2500 A and a short-circuit current of 40 KA for 3 seconds. The standardized protection and control cabinets are housed in a separate adjacent room. A 110 kV E-coil is to be installed on the first floor and connected to the 110 kV star points of the transformers. The isolators to be supplied are located in the E-coil room. All required connections are to be taken into account in the scope of the project. The 20 kV primary switchgear and the star-point switchgear are located on the ground floor. The primary switchgear is to be implemented as an air-insulated double busbar with a nominal current of 2500 A and a short-circuit current of 25 Ka for 3 seconds. It comprises 42 panels, two of which are to be provided as space reserves. The switchgear is divided into three busbar sections that are connected to one another via two longitudinal couplings. Sections 1 and 3 also contain cross-couplings. The star-point switchgear is to be implemented as an air-insulated single busbar, comprises 11 panels and can be connected to one another via three longitudinal couplings. It is to be designed for a nominal current of 1250 A and a short-circuit current of 20 Ka for 1 second. Two 20 kV E coils, a grounding transformer and the 20 kV star points of the transformers provided are to be connected to this system. All required connections are to be taken into account in the scope of the project. The AC and DC switchgear and the batteries for the DC supply are located in the first basement. The DC switchgear is to be designed redundantly and includes two batteries, each with 200 Ah at 220 Vdc. The AC switchgear includes six panels, including a feed panel for the 400 kVA auxiliary winding of the grounding transformer, a feed panel for a 400 A house connection and one for the emergency power system. In addition, three fans are installed in the basement for ONAF operation of the 110 kV transformer rooms. All technical components are to be designed in accordance with the current standards and regulations.
