Specialists of Rosseti Kuban have completed work on the restoration of the destroyed 110 kV Ilyich substation in the suburbs of Mariupol in the Donetsk People's Republic (DPR). The substation is a transit one along the 110 kV network and provides power supply to one of the largest industrial enterprises of the Azov region and the DPR - the Mariupol Ilyich Iron and Steel Works.

A new battery was installed at the facility, more than 900 m of busbars (bus duct) were installed, which were stolen from the territory of the power center.

The roof of the closed switchgear and the glazing of the general substation control room were also restored.

Earlier, the power engineers of Rosseti Kuban completed repair work on the 110 kV overhead power line Zarya-Ilyich No. 1 in Mariupol.
