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