Cold Shrink
Benefits for MV Power Systems
- Tight Cable Sealing – MV joint or termination retains resiliency and pressure after prolonged aging and outdoor pollution exposure
- Flexible Cold Shrink – accommodates all power cable manufacturers bend radius tolerances and recommendations
- Reliability – high dry and wet insulation resistance for direct burial cable joint or outdoor termination
- Outdoor Cable Terminations – excellent resistance to ozone and ultra-violet radiation
- Versatile – Cold Shrink joints or terminations install quickly and accommodates a wide range of cable sizes
- Dependable – proven long-term reliability and safe operation at overload temperature on MV HV power system networks
- Time Efficient – reduced installation time for the Jointer compared to heat shrink, electrical taping or resins
