OREANDA-NEWS. July 15, 2010. The decision to build a new substation in the area adjacent to the existing one was taken because of the maximum load of the existing substation 110/10kV "Gorky" which is located at Safiullin Street and because of the prospect of development of the surrounding area. The largest increase in load will provide input to the system of objects of Universiade 2013 in this area.

At the present time the process of carry-over of the existing buildings and structures from the territory of a future substation has done. Still the range of construction works on the zero cycle is continuing. The preparation work has done to overcharge the substation from the existing network of 110 kV cable with XLPE insulation.

The substation "Gorky" has two transformers -2x25 MVA. In accordance with the magnitude of prospective load, it is planned to supply power from it, and according to the technical project power transformers 2x40 MVA are taken for the installation. Closed switchgear (indoor switchgear) 110kV will be located on the second floor of the substation. 110kV gas-insulated circuit breakers type of VEB-110 production of UETM and disconnectors SGF-110 manufactured by ABB will be installed.

On the ground floor in the facilities of 10kV indoor switchgear 10 kV "Volga" production by "INVENT-Electro "will be installed.

System of substation relay will be based on complete multifunction production of NNN "Ekra", performed by the use of microprocessor-based terminals.

The construction of indoor substations of the city, where all the equipment is placed inside the building, JSC "Grid Company" has begun in 2004. All transformers of the substation are safe and sound insulation will not disturb the population, this is an important factor for the city. Closed substation is fully protected from the influence of environment, and ensures the safe operation of the equipment. They are perfectly fit into the residential quarters of cities of the Republic of Tatarstan, and their construction allows saving building-up area.

The new substation doesn’t need permanent staff. Operational services will be carried out by teams of Kazan electrical grids.
