Description

ABTM/ABTH is produced from specially formulated radiation cross-linked halogen free compounds and provides a high resistance to tracking and arcing, this enhances the insulation properties of busbars in switchgear and substations.

 

Features

  • Flexible to ensure ease of installation
  • Shrink Ratio 2.5:1
  • Excellent tracking resistance & insulation
  • Halogen Free
  • Superior resistance to UV and weather conditions
  • Colours – Red
  • Minimum fully recovered shrink Temperature, 120 °C

 

Applications

  •  Suitable for applications in LV and MV(36kV) switchgear and electrical equipment.
