This contract included delivery of two transformer stations with the 1750 kVA power and 6/1kV ratio, type EH-d31-1750/6,0/1,0/4/01, two maneuvering sets with the 1800A continuous disconnecting current, type EH-d03-W/1,0/III/027.21. Control and visualization system was also performed.

This contract included three transformer stations integrated with maneuvering sets. Control and visualization system was also performed.

This contract included delivery of transformer stations with the voltage ratio 6/3,3kV, contactor switches, communication and interlocks system with sensors. Control and monitoring system was created including remote parameterization of protections. The control system was configured so that the control is possible from both ploughed wall and from mine head.

This contract includes delivery of transformer stations with the voltage ratios of 6/3,3kV, contactor switches, communication and interlocks system with sensors and leads for the voltage of 3,3kV. Control and monitoring system was created including remote parameterization of protections.
