REPLACEMENT OF EQUIPMENT AT RAAZIKU SUBSTATION

As part of the reconstruction program for traction substations of Estonian railways, equipment is currently being replaced at Raaziku substation.

TET ESTEL, together with AS Connecto Eesti, won the tender organized by Estonian Railways Ltd. for the supply of a new traction transformer-rectifier unit for this substation. Work started by dismantling of old equipment, which was replaced by new in April 2020:

∙ Rectifier (3,5kV, 3000A) manufactured by TET ESTEL replaced the old rectifier manufactured by our company many years ago.

∙ Oil transformer (6300kVA)

Installation supervision and commissioning are scheduled for June. At the end of the tests, the traction substation will be fully commissioned, increasing the reliability of energy supply for trains passing in this direction.
