Heat Shrinkable Tubes/Heat Shrink Sleeves 
Non Tracking tube - INSULTUBE non tracking
Insultube - Nontracking is used in Medium Voltage Cable Joints and Terminations up to 36 KV. The tubes are produced from high quality non-tracking cross-linked polyolefin material that offers exceptional insulation and long-term service reliability.
General Properties
- Excellent anti-tracking performance and erosion resistance.
- Halogen free, flame retardant.
- Good weather / UV resistance.
- High resistance to chemical, solvent, corrosion and fungus.
- Customised dimension, thickness, length & colour available on request.
