High-voltage transformer substations are intended for reception, transformation and distribution of electrical energy. Depending on the technical requirements of the project the design and the distribution of nodes may be different. The designed and newly built substations are equipped with modern facilities and meet international standards. Switchgear set may be open or closed. Depending on the distribution, the schema and configuration of electrical network, the company produces transformer substations with capacity of up to 25000KVA and the input voltage up to 110kV.
