OREANDA-NEWS. It is erected near the SS "Vostochnaya", that has operated over forty years. Load of transformers here is 95 %. In view of growing electricity consumption in Kazan the old facilities would not cover in full the demand. In the first turn this is related to extensive construction of housing, infrastructure development, household consumers increased loads. According to the "Scheme of grid development in Kazan and Kazan power region" and realized by "Tatenergo" program fro increase of capacity of substation s in capital of Tatarstan, in 2006 started erection of the new substation. It is an indoor substation because of its close proximity to residential houses.

General contractor of construction dimension of the project is the construction firm "Gran, Ltd". New three-storey building of SS, of total area of over four thousand of square meters is practically ready to acceptance and equipment mounting will start in October. General contractor of technical dimension will be the JSC "Srednevolzhskselelektrosetstroy".

At substation "Vostochnaya" will be installed the new power transformers 2х63 МVА.They are more powerful than existing twice, this would allow to connect new consumers. In separate rooms will be located the current limiting reactors and hi-frequency treatment facilities. On side of 110 kV as commuting devices will be installed the set-up SF6 switchgear (KRUE) by АВВ, – it was initially realized at SS "Novo-Kremlevskaya". In indoor switchgear 6 kV will be installed the cabinets KRU by "Schneider Electric" with SF6 switches. Panels of relay protections with microprocessors for the new substation are made by Cheboksary NPP "EKRA".

The nearest to substation poles of aerial electricity transmission line 110 kV from SS "Tsentralnaya" and "Magistarlnaya" wil be disassembled and ways to SS " Vostochnaya" will be made of cable insulated by cross-linked polyethylene. Laying the cables will allow to save the place for building – security area of underground piping is less in area than at electricity transmission lines.

After commissioning the new substation the existing "Vostochnaya" will be dismantled and its territory will be planted the greens. The power engineering specialists plan to finish construction of substation in December 2007 and it will be one of the most modern in Volga region. As a result the 110 kV network flexibility will increase much as well as dependability of power supply by distribution grid 6 kV of the region.
