Anti-Tracking Tubes |
|
|
| |
| |
Heat Shrink Non Tracking Tubes are Used In Medium Voltage Cable Joints and terminations upto 36 KV. The tubes are produced from high quality non tracking cross linked polyolefin material that offers execptional insulation and long term service reliability.
Excellent anti - tracking performance and erosion resistance.
Hologen free, flame retardant.
Good Weather / UV resistance.
High resistance to chemical, solvent, corrosion and fungus. |
