The substation consists of the three switch cells I, II and III. Cell I is powered, or is powered by cable 11, while cell III is powered by cable 12 is supplied or this supplied, wherein the cables 11 and 12 are parts of a Yersorgungsstromkreises. The outer Boxes 13 and 14, respectively, are attached to compartments 15 and 16, respectively, each of which contains a switch. These Switches are identical to the three-phase switch 17 in of section 18 of cell II. The electrical connection between the wires of the cable and the switches will be öhareh Rails, such as rail 19 in cell II, are made.
