Project Description ：Construction of a complete power supply infrastructure for the new dairy barn project at the Teaching and Research Estate of the University of Munich (LMU) in Oberschleißheim. The scope of work covers the entire electrical connection from the existing medium-voltage system to the new cattle barn, including the construction of a new switchgear station, laying of medium and low-voltage cables, installation of a complete set of switchgear and transformers, and restoration of ground facilities.

Switchgear Station Structure ：1 concrete compact substation, consisting of 2 concrete chambers

Medium-Voltage Switchgear ：1 set, 4 bays, required to be SF6 gas-insulated (fluorine-free), including DC power supply and protection technology.

Emphasis: This is a core equipment of the project and must be supplied strictly in accordance with the technical specifications.

Transformers ：2 units, 630 kVA cast resin transformers

Low-Voltage Switchgear ：1 set, low-voltage main distribution board (NSHV), 5 bays.

Emphasis: This is a core equipment of the project, responsible for the internal power distribution of the farm.

Medium-Voltage Cables ：Approximately 1,000 meters (single-core)

Low-Voltage Cables ：Approximately 2,000 meters

Cable Pits ：Approximately 12 cable pulling pits

Protective Conduits ：Approximately 1,800 meters

Earthworks ：Approximately 800 cubic meters of cable trench excavation

New Switchgear Station Construction ：Construction of a compact substation consisting of 2 concrete chambers, including related excavation, foundation works, and grounding system installation.

Medium-Voltage Switchgear Supply and Installation ：Supply and installation of a 4-bay SF6 gas-insulated (fluorine-free) medium-voltage switchgear. This switchgear must integrate DC power supply equipment and complete relay protection technology.

Transformer Supply and Installation ：Supply and installation of 2 units of 630 kVA cast resin transformers, and completion of the primary-side (medium-voltage side) cable connection and wiring work for the transformers.

Low-Voltage Switchgear Supply and Installation ：Supply and installation of a 5-bay low-voltage main distribution board (NSHV) for the internal power distribution of the farm.

Cable Duct Construction ：Construction of a complete system of cable pulling pits and protective conduit pipelines for laying power and control lines. This system must extend from the new switchgear station to the connection point of the existing medium-voltage system on the estate.

Road Surface Restoration ：Upon completion of the works, all excavated asphalt road surfaces must be restored.

Fiber Optic Connection ：Laying of fiber optic lines to connect the new substation to the estate's central IT main distribution frame for communication and control.
