HEAT
SHRINK WRAP AROUND SLEEVE |
Application :
-
Repair the outer / inner sheath damages on the
cable.
-
Provides corrosion protection to the
metallic parts of the cable that are exposed to polluted
environments
-
Provides moisture proof protection to corrosion
prone oil, water and gas pipelines.
-
Protection for Telecommunication cable joints.
Features :
- Made from thermally stabilised,cross linked polymeric
material.
- Shut down system not required for repair.
- High Shrink ratio covers even irregular shapes.
- Hot melt adhesive provides complete environmental sealing and
insulation.
- High resistance to UV rays,chemicals,corrosion,fungus etc.
- Temperature sensitive paint changes colour when heat shrinking
process is complete.
