Opening ceremony of a new tram line connecting old and new parts of Naberezhnye Chelny with participation of Tatarstan President Rustam Minnikhanov took place on December 12, 2014. Length of the new line is 6.2 km in single-track valuation.
Since the line opening within the first month of its operation more than 660 thousand people have enjoyed the new routes. After introduction of the new line into service passenger traffic can increase up to 30 million people per year according to calculations of "Electrotransport" Ltd.
The project is unique in the innovative technical solutions applied during construction. In particular, a modern unattended three-unit modular substation was installed to ensure reliable and uninterrupted power supply of the new tram line section. Delivery was made by Moscow company CJSC ETC "Pluton", which belongs to Group of companies "Pluton".
Application of modern equipment, being a part of the new modular substation, greatly reduces substation operating and maintenance costs.
Electrical and operating characteristics of switching devices applied in equipment significantly exceed similar characteristics of devices used in substations of old-design. Due to high mechanical and electrical reliability we ensured 30-year lifetime of the new generation of switching devices, as well as significantly reduced the periodic maintenance (up to 1 time per 10 years).
Application of maintenance-free contact connections in power part of equipment eliminates the need for their control, periodic tightening and cleaning, and this also helps to reduce costs during the whole life cycle, and significantly increases fire safety of equipment and substation as a whole.
Modular substation includes the following equipment:
- 3 pcs.;
- Switchgear 6 kV series NEX - 1 set;
- Resibloc transformer - 3 pcs.;
- Rectifier - 3 pcs. ;
- DC Switchgear - 12 cubicles;;
- Auxiliaries equipment- 1 set;
- Set of SCADA equipment - 1 set.
Modular substation is also equipped with lighting, ventilation, air conditioning, heating, security alarm and fire fighting systems.
The new modular traction substation is unique as it works automatically, without staff. In the nearest future it will be possible to remotely control the substation wirelessly from dispatcher control depot.
Company "Pluton" congratulates citizens of Naberezhnye Chelny with opening of a new tram line and wishes the project of such a scale to give a jump start for the further development of the city transport infrastructure!
