The transformer substation will become the main power source for crane equipment, pump groups, concrete distributing booms, electrical installations, welding machines, etc.
This separate investment project is important for the timely supply of electrical power to all consumers and the needs of the units under construction. Its implementation began long before the main period of construction of the station.
At the end of December, a stationary three-phase power transformer weighing more than 40 tons was delivered to the site. The electrical installation reduces high voltage from 110 kV to 10 kV. Last year, Titan completed the construction of a foundation slab with an oil bowl for the installation of the transformer. This is one of the safety systems, in the event of an accident; it will prevent the release of oil from the cooling system and redirect it to the oil tank, which has also already been installed.
Currently, the main contracting works at the site are carried out by JSC SEM. The third, fourth and fifth sections are carrying out a complex of finishing works, installing ventilation systems and split systems (heating and cooling), and closing the external and internal grounding circuit. In the near future, works will be completed to ensure construction readiness for the arrival of the main equipment. Builders will begin installing crane equipment, installing the heating system, lighting, socket network, and potential equalization system.
At the moment, about 30 people are working here. During the testing and commissioning period, it is planned to increase the number of employees. The company's specialists will have to install and put into operation the automated process control system, relay protection and automation, panels, a complete distribution device, access control and accounting systems.
