Heat Shrinkable Tube/ Heat Shrink
Sleeves 
Oil Barrier Sleeves
Insultube Oil barrier sleeves is applied to PILC Cables for preventing the cable oil from dripping out and increasing the insulation up to 36 kV. These tubes are made from high quality cross linked polyolefin material.
Features & Benefits:
- Oil-resistant material prevents oil penetration.
- High dielectric strength for excellent electrical insulation.
- Seamless shrink fit for a tight, uniform seal.
- Chemical and corrosion resistance against oils, fuels, and industrial chemicals.
- Durable and flexible design for easy installation.
- Suitable for oil fields, refineries, and heavy industries.
- Extends cable life by reducing wear and tear.
- Reliable sealing to prevent leaks and contamination.
- Reduces maintenance costs by minimizing replacements and repairs.
