Heat Shrinkable Anti-Tracking Tubings

Heat Shrinkable Anti-Tracking tubing's are produced from cross-linked polyolefin material that offers exceptional insulation and long term service reliability. Due to its excellent non-tracking and erosion resistance inbuilt character, these tubing's find proven applications in electrical and electronic segment such as:

  • An Integral part of heat shrinkable power cable terminations upto 36 KV for indoor & outdoor applications.
  • An integral part of heat shrinkable straight through joints upto 36 Kv in combination with other electrical supporting device.

Features :

  • Excellent anti-tracking performance and erosion resistance.
  • Excellent Flame retardant  properties
  • Good Weather/ UV resistance.
  • Non-carbon Material
  • Excellent chemical resistance
  • Protects against accidental flash overs
  • Halogen free
  • Easy installation and removal
  • High dielectric strength
  • Compliance with ESI 0-13 standard
