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.
