3M produces cold shrink joints and terminations for low voltage cables using prestretched tubes. The tubes are factory expanded and placed over cable connections or terminals, with a removable core inside. Removing the core allows the tube to shrink and provide a waterproof seal. The cold shrink kits can be used on various cable types rated from 0.6/1kV to 1.9/3.3kV, require no special tools or heat, and accommodate a wide range of cable sizes.
