Koryazhma Pulp and Paper Plant is a member of Ilim Group, the leader in the pulp and paper industry in Russia and one of the leading industry players in the world. Since 2008, the plant has undergone a large-scale modernization, designed to provide a fast-growing Russian market with high-quality paper of domestic production. Within the framework of the Big Koryazhma project a new office paper production was built for which DKC transformers with cast insulation of 2500 kVA 6 / 0.4 kV D / Yn-11 with protective casing and forced ventilation (art. TDA25BDYN1BF000) were supplied.
After the project implementation in Koryazhma, the plant began producing chalk-paper, which made the Ilim Group the first and single Russian producer of this product.
