High-Voltage Union is one of leading CIS companies, which manufactures modular transformer substations from 110 to 0,4 kV of transformers’ capacity from 25 kVA up to 40 MVA.

Nowadays the plant produces in 110 kV voltage class modular transformer substations KTPBR-110/35/10(6) and KTPBR-110/10(6) of 110 to 35 and 10(6) kV voltage transformation equipped with transformers from 2 500 kVA to 40 MVA;

Modular transformer substations KTPBR-110/20 kV voltage transformation equipped with transformers from 2 500 kVA to 40 MVA;

KTPBR-110 supply includes the following basic units and elements:

• one or two power transformers;

• outdoor installed switchgears of 110 kV with rigid and flexible bus system elements;

• outdoor or indoor (in modular steel housing or capital building)) installed switchgears of 35 kV with rigid and flexible bus system elements;

• switchgears of 10 kV mounted in a permanent building or in a modular steel housing;

• substation control unit;

• telecommunication and remote control equipment and apparatus, power backup sources;

• auxiliary transformer cabinets with a capacity from 25 to 250 kVA;

• lightning guard, grounding, lighting devices, barrier, spare parts, instruments and accessories, set of individual and fire protection as well as other units and elements in accordance with the substation project.

‘Turn-key’ project management is one of the priorities of High-Voltage Union. Such projects make the company responsible for all the stages of the substation construction: starting from the project consideration up to putting into operation. Operation experience of dozens of substations built by the company showed their reliability and confirmed cost-effectiveness of the substation construction.
