Railway Industry

Smooth rail transport requires components that are designed for longevity, reliability and continuous use. Thanks to their unique combination of resistance, robustness and durability, WACKER silicones meet exacting demands.

WACKER silicones can be found in the interior and exterior of railway vehicles – for instance, in cables, bellows for connecting wagons, in door and window pane seals, or in electrical and electronic components of railway drive and control systems.

Most of the current fire safety requirements for railway vehicles, especially those subject to R22 and R23 requirement sets, can be met with certified solid and liquid silicone rubbers from the existing product portfolio.

Benefits:

  • Flame retardant
  • Low smoke toxicity
  • Peroxide-cure
  • DIN EN 45545-2 compliant

Applications:

  • Window seals for fitting and sealing window panes
  • Door seals
  • Bellows for connecting wagons

Additional potting of the slot exits and the electrical junction boxes with low-viscosity, flame-retardant silicone rubber reliably prevents moisture penetration. Together with a winding head coating of weather-resistant RTV silicone, our product solutions ensure a long service life and form an integral part of an electrical insulation system for drive motors that has proven itself worldwide for over 40 years.

Benefits:

  • Very high heat resistance
  • Optimized electrical insulation
  • Improved thermal management
  • Long-lasting protection against environmental influences and the effects of weathering

Applications:

  • Vacuum-pressure impregnation (VPI) of electrical windings in traction motors
  • Potting of slot exits
  • Potting of electrical junction boxes
  • Winding head coating
