3M™ Cold Shrink Silicone Insulators 8440 series is made of highly elastic Silicone rubber and is used both for the electrical insulation of polymeric or rubber-insulated cables up to 1 kV and for the protection and sealing of non-electrical applications. It also reliably protects connections between cables with different diameters.
The 8440 series is suitable both for indoor and outdoor applications as well as for underground or underwater installation. In addition, the Cold Shrink tubing ensures flexible kink protection and can also be used for cable sheath repairs. Quick and easy assembly by pulling out the supporting core enables reliable installation without special tools, such as heating burners. After assembly, the cold shrink tubing ensures reliable protection against moisture thanks to its constant radial contact pressure. Its excellent thermal stability and its resistance to acids, alkalis, ozone and UV radiation guarantee long-term functionality, while its self-extinguishing properties ensure a high level of safety.
Suggested applications
- Primary electrical insulation for all solid dielectric (rubber and plastic) insulated wire and cable splices
- Electrical aircraft cables
- Sealing for high-voltage air insulated connectors and lugs
- Insulation of secondary splices copper or aluminium conductors and inline conductor transition connectors
- Sheath repairs
