Railway Insulators FullScreen
  • Features
  • Help & Support

Polymeric Insulator for railway application up to 25kV. Polymeric Railway Insulators combine mechanical strength with excellent pollution performance. High tensile strength of glass fiber combined with HV shed profile makes the insulator rugged and light weight for traction application.

  • Make in India
  • Compact design and break resistant

  • Excellent tracking and erosion properties

  • Hydrophobic properties for excellent pollution performance

  • No maintenance required

  • Light weight and easy installation

  • Patented crimp design to maximize mechanical strength
