The Universal Silicone Repair Tape 

The high dielectric strength of Wrap & Seal makes it perfect to insulate electric cables and joints. It will also prevent the ingress of moisture, a common problem in outdoor installations. Joints made with Wrap & Seal can be cut open for repairs, without leaving a sticky film. Damaged telecommunication cables are easily repaired where expensive repairs are normally required; even cable joint boxes can be sealed.
