13 May 2025
Electronmash has successfully fulfilled its obligations to manufacture and supply electrical equipment as part of the construction of a new tailings storage facility in Dubenka Gully in the Belgorod region.
Lebedinsky GOK JSC plans to build a new tailings storage facility in the Dubenka Gulch. The new tailings storage facility will be in operation for 15 years.
JSC Electronmash supplied a 6 kV indoor switchgear located in a block modular building combined with a general substation control center. In the building of the 6 kV control room there are 19 cells of the 6 kV Eltema MVS with a rated busbar current of 2500 A. The Eltema MVS is equipped with Russian-made equipment: power switches, current transformers, surge arresters, relay protection and automation terminals. The 6 kV Indoor switchgear is equipped with its own DC system. There is also an substation control room in the building, which provides relay protection panels designed for reliable and selective protection of equipment from emergency modes of operation. The control center is equipped with a 0.4 kV Assol auxiliary switchboard to provide power to the substation's own equipment. Data is collected and transmitted from the 6 kV indoor switchgear to the upper level using the IEC 61850 protocol.
In addition, a 35 kV indoor switchgear was supplied in a separate block modular building, including 10 35 kV Eltema+ MVS cells with a nominal busbar current of 1000 A. The equipment is also fully Russian-made and includes all the necessary components for reliable and safe operation.
Within the framework of the contract, the specialists of JSC Electronmash will also perform installation supervision, providing technical support and consulting services during installation work on the assembly and connection of equipment.
JSC Electronmash would like to thank JSC Lebedinsky GOK for their trust and choice of our company as a supplier of electrical equipment for such a significant project. We are pleased to be a part of the development of one of the largest mining and processing plants in the country and are confident that our equipment will be a reliable basis for stable and efficient operation of the new tailings storage facility.
