In my muster thesis I investigated the issue of the possible reconstruction of the power supply scheme in the Tomsk enterprise of heavy industry "Sibelektromotor". The urgency of the work lies in old-fashioned material insulation. For many years due to the alternative absence, cables with impregnated paper insulation (IPI) were applied for transmitting power. IPI cables have many evident drawbacks, that decreases reliability of power supply. Nowadays, they are still under operation but they are being replaced by the new type of insulation material - cross-linked polyethylene (XPLE). This material has a large number of advantageous features over paper insulation, that gives a strong reason to consider the reconstruction of the system. In the theoretical part I described the insulating materials, their technical characteristics and made a competitive analysis upon the obtained information. The technical part contains designing of power supply systems. The economic feasibility of the two projects is described in the economic part. This part contains calculations of the investment cost, maintenance of the cables, where losses is the essential part. I also provided sensitivity of the project to different rates. In the last part I drew conclusion of the work upon the obtained calculations and the theoretical base and provided my recommendations.
