Polymeric Insulators

Features :
  • Specially Designed Polymeric Material Used in these insulators have a self-cleaning property, achieved by molecular migration making it possible to maintain anti-tracking performance over an extended period.
  • These composite insulators are practically unbreakable.
  • Surface hydrophobicity is maintained over a long period. This is very valuable in a polluted environment.
  • Excellent performance in highly polluted environments.
  • Excellent flame/arc resistance.
  • Highly resistant to chemical and UV rays.
  • Compact weight and light weight(Approx 25-30% of ceramic insulators.)
  • Metal end fittings as per  requirement to end applications.
  • High tensile strength FRP pultruded rod ensures excellent mechanical strength to an isolation system.
  • A central rod of fibre rein-forced polymer composite
  • A housing made from a special tracking polymer. This housing provides protection against environmental factors like pollution, heat, humidity and UV resistance.
