GDT-Hx

For high exposure track circuits – replacement for early technology air gap and MOV components

The Novaris GDT-H1-3G and GDT-H2-6G provide protection for track circuits. These units utilise fast acting, high energy gast discharge tubes. These provide a replacement for early technology air gap and MOV components. These are used for railways track circuits and connect directly to the conductors from the rails. Panels without gas tubes are available as GDT-H1 and GDT-H2.Gas tubes are available as GDT-100-350-RPU.

  • Uses GDT-100
  • Single and two pairs
