Heat Shrinkable tape with low melting point adhesive layer for wrap around repair. Usually applied by enwind around the electrified object with half of tape overlapping previous turn.
The tape, when heated, shrinks around the substrate while hot melt adhesive fill the gaps and fusion with the tape to form into one piece insulation.
Applications
Emergency repair of electrical power system .insulation and protect of odd-shaped electrified objects, where tubal / sleeve shaped insulation materials are not applicable.
Reduce space allowance between phase to phase bus bar.
Features/Benefits
Low melting point high polymer adhesive layer for easy installation.
Conform to irregular shaped objects where tubal / sleeve jacket insulation material is not applicable.
Compatible with most other insulation materials.
