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.
