Siemens is supplying thyssenkrupp with state-of-the-art electrical equipment consisting of 8DA10 (gas-insulated) and NX-AIR (air-insulated) medium-voltage switchgear, transformers, low-voltage energy distribution, Sinamics SL 150 and Sinamics S150 frequency converters as well as low-speed synchronous motors with a nominal power of 5.5 mw and smaller squirrel cage induction motors. The delivery also includes pre-assembled ?E-Houses? for installing the equipment as well as power factor correction and harmonic filtering equipment. To fulfill the requirements of the underground environment, the dimensions of those ?E-Houses? were reduced to an absolute minimum.

The transport system consists of a total of nine conveyors ? seven underground and two at surface. Four of these conveyor belts have a gearless design, each with two 5.5 mw drive systems.
