22 -28 KV Composite Insulators

Guaranteed Technical Particulars

Advantages

Advantages of Composite Insulators over Ceramic Insulators :

  • Light weight
  • Ease of Installation
  • Long term surface hydrophobicity and insulating properties
  • Superior anti-tracking properties
  • Resistance to breakage and vandalism; practically unbreakable
  • Unique self cleaning property
  • Suitable for polluted environment and salty atmosphere etc.
  • High mechanical strength
  • Choice of end fittings
  • Long Life
  • Reduced maintenance cost
  • Power loss by leakage current across the insulator is minimized using a special polymer compound
  • Compliance with IEC:61109

* The design and material of end fittings as per Standard / Customer requirement
