The project is an important part of the Vilnius\u2013Klaip\u0117da railway electrification project of national importance, being developed by LTG Infra. <\/p>\n\n<p class=\"wp-block-paragraph\">Tetas specialists constructed a 110 kV switchgear, a double-circuit 110 kV overhead transmission line \u017deimiai\u2013\u017deimiai Traction, as well as a 110 kV overhead line \u017deimiai Traction\u2013K\u0117dainiai. The total length of the newly installed electricity transmission lines is approximately 1.5 km. <\/p>\n\n<p class=\"wp-block-paragraph\">The 110\/27.5 kV \u017deimiai traction transformer substation is already the second of six traction substations connected to the transmission network operated by Litgrid. It will ensure a reliable electricity supply for electric trains along the country\u2019s main railway corridor. The switchgear was constructed under a contract with LTG Infra.  <\/p>\n\n<p class=\"wp-block-paragraph\">Once the Vilnius\u2013Klaip\u0117da railway electrification project is completed, a 363 km-long overhead contact line system will be installed. The project covers not only the construction of the contact network, but also the construction of six traction substations in Lentvaris, \u017deimiai, Linkai\u010diai, Tarvainiai, Kretinga and \u017dasliai, their connection to the Litgrid electricity transmission network and testing, as well as the installation of eight autotransformers to ensure voltage stability in the contact network. The Lentvaris traction substation was the first to be connected to the transmission network, followed by the \u017deimiai substation.  <\/p>\n\n<p class=\"wp-block-paragraph\">The Vilnius\u2013Klaip\u0117da railway line is the busiest railway section in Lithuania, making its electrification critically important for the development of the country\u2019s infrastructure. Last year, this corridor accounted for approximately 40% of all rail freight and 16%   of passenger traffic in Lithuania.<\/p>\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"768\" data-id=\"83291\" src=\"https:\/\/tetas.lt\/wp-content\/uploads\/2025\/12\/zeimiai-3-1024x768.png\" alt=\"\" class=\"wp-image-83291\" srcset=\"https:\/\/tetas.lt\/wp-content\/uploads\/2025\/12\/zeimiai-3-1024x768.png 1024w, https:\/\/tetas.lt\/wp-content\/uploads\/2025\/12\/zeimiai-3-300x225.png 300w, https:\/\/tetas.lt\/wp-content\/uploads\/2025\/12\/zeimiai-3-768x576.png 768w, https:\/\/tetas.lt\/wp-content\/uploads\/2025\/12\/zeimiai-3-1536x1152.png 1536w, https:\/\/tetas.lt\/wp-content\/uploads\/2025\/12\/zeimiai-3.png 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"768\" height=\"1024\" data-id=\"83287\" src=\"https:\/\/tetas.lt\/wp-content\/uploads\/2025\/12\/zeimiai-2-768x1024.jpg\" alt=\"\" class=\"wp-image-83287\" srcset=\"https:\/\/tetas.lt\/wp-content\/uploads\/2025\/12\/zeimiai-2-768x1024.jpg 768w, https:\/\/tetas.lt\/wp-content\/uploads\/2025\/12\/zeimiai-2-225x300.jpg 225w, https:\/\/tetas.lt\/wp-content\/uploads\/2025\/12\/zeimiai-2-1152x1536.jpg 1152w, https:\/\/tetas.lt\/wp-content\/uploads\/2025\/12\/zeimiai-2.jpg 1440w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"768\" height=\"1024\" data-id=\"83289\" src=\"https:\/\/tetas.lt\/wp-content\/uploads\/2025\/12\/IMG_20251105_135533-768x1024.jpg\" alt=\"\" class=\"wp-image-83289\" srcset=\"https:\/\/tetas.lt\/wp-content\/uploads\/2025\/12\/IMG_20251105_135533-768x1024.jpg 768w, https:\/\/tetas.lt\/wp-content\/uploads\/2025\/12\/IMG_20251105_135533-225x300.jpg 225w, https:\/\/tetas.lt\/wp-content\/uploads\/2025\/12\/IMG_20251105_135533-1152x1536.jpg 1152w, https:\/\/tetas.lt\/wp-content\/uploads\/2025\/12\/IMG_20251105_135533-1536x2048.jpg 1536w, https:\/\/tetas.lt\/wp-content\/uploads\/2025\/12\/IMG_20251105_135533-scaled.jpg 1920w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/><\/figure>\n<\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Commissioned by Litgrid, Tetas has successfully completed the works to connect the \u017deimiai traction transformer substation to Lithuania\u2019s electricity transmission network.
