Heat Shrinkable Tubes/Heat Shrink Sleeves 
Non Tracking tube - INSULTUBE non tracking
Insultu - Non Tracking tubesbe are used in Medium Voltage becable joints and terminations upto 36 KVbe. 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.
