General description

Electroshield Samara is one of the leaders in production of complete transformer substations for voltage of 35, 110 and 220 kV.
Electroshield Samara manufactures modernized packaged modular transformer substations KTP SESH B(M) of voltage classes 35, 110 and 220 kV. Since 2005, the enterprise performs engineering, production and supply of indoor distribution substations for voltage of 35, 110 and 220 kV.

Technical information

The substations produced in Electroshield Samara reliably operate in all regions of the Russian Federation, near and far abroad. The substations are designed for all typical electric wiring diagrams applicable in the country. Substations for non-typical diagrams can be developed as well. Working, engineering and process flow documentation is developed taking into account the comments and proposals of design institutes and operating organizations. All metal structures for the equipment and rigid busbar are coated with hot zinc. Assembly on the installation site is made without welding as the bolted connections are used.

The design of the substations allows future step-by-step expansion without additional reconstruction work. Substation delivery as factory-assembled units allows to reduce significantly installation time, improve product quality, and increase equipment performance reliability. The main part of high voltage apparatus is manufactured in production sites of Electroshield Samara and the equipment of Russian and foreign manufacturers is used. Standard and -non standard units of the metal structures ensure the guaranteed compatibility of the applied equipment. They are provided with rigid busbar which has improved resistance to wind, ice, seismic loads.

Rigid busbar can be delivered either within substation or separately. Substation can be fully equipped with systems of Relay Protection and Automation, Process Automation, Automated Measuring and Information System for Electric Power Fiscal Accounting. Most of the substation elements are integrated into the digital substation concept and meet the requirements of IEC 61850.
