Кантактная сетка — тэхнічнае збудаванне электрыфікаваных чыгунак і іншых відаў транспарту (метро, трамвая, тралейбуса, фунікулёра), служачая для перадачы электраэнергіі з цягавай падстанцыі на электрарухомы склад.

Акрамя таго, з дапамогай кантактнай сетцы забяспечваецца снабженне нецягавых чыгуначных спажыўцоў (асвятленне станцый, пераездаў, сілкаванне пуцяво́га інструмента).

Кантактная сетка бывае двух тыпаў:

Нягледзячы на тое, што на рэйкавым транспарце хадавыя рэйкі звычайна прымяняюцца для адводу зваротнага цягавага току, — яны, як правіла, не разглядаюцца ў якасці часткі кантактнай сетцы.

Асноўнымі элементамі кантактнай сетцы з'яўляюцца:

  • Апоры і апорныя канструкцыі
  • Кантактныя падвескі
  • Арматура і спецчасткі
  • Кантактныя, сілкуючыя і ўзмацняючыя правады, падключаныя к электрычнай сетцы

За эксплуатацыю ўсіх элементаў кантактнай сетцы на эксплуатуемых участках, іх абслугоўванне і рамонт на чыгунцы адказвае дыстанцыя кантактнай сетцы.
