Railway overhead line systems

Railway overhead line system

This patented retractor system is used to tension the overhead contact lines on electrified railway lines. Each retractor unit is an assembly with multiple power springs and can be shipped in a range of extension lengths and tensile forces (10 - 36 kN) depending on customer requirements.
  • Variable models:10KN/12KN/15KN/20KN/24KN/25KN/32.5KN/36KN.
  • Variable extraction/retraction length (0.8 m - 2 m).
  • Total hysteresis (extraction force & retraction force) is within ±4% over working range.
  • 20,000 lifecycles over working range simulation test.
  • Reliable self-brake system.
  • Visible force monitoring systems.
  • Compact design, clean optics, easily adapted to the landscape of the city.
  • Needs little space for installation, which is highly suitable for tunnels, bridges, stations and windy areas.
