During the first work stage, the JSC CONCERN TITAN-2 specialists will lay a cable line of 4 km, which will connect the transformer substation 110/10 with the outdoor switchgear ORU-110 kV of the Leningrad NPP. After that, the works will commence to construct the transformer substation building intended to supply power.
“The substation construction work schedule is set up until the end of the year. We shall commence electrical equipment installation in September and power supply to the power transformer in December. At the moment, the crushed stone foundation is already completed and the reinforced concrete trays for the cable line are installed, the cable is ready for winding. 72 persons will be engaged during the most extensive shift of the substation construction. They are well-experienced specialists of our company”, noted Konstantin Khudyakov, Program Director for Leningrad NPP Facilities of JSC CONCERN TITAN-2.
Upon completion of the construction structures, an installation of more than a thousand of items of electrical equipment, relay protection, controls, ventilation and air conditioning equipment, etc. will start.
After commissioning of the new power units, the transformer substation will be in the standby mode. In case of an emergency and loss of main or backup power supply, its equipment will commence operation within a fraction of a second to provide power to the auxiliary equipment of the power unit.
