The new 3M cold shrink foldback splice jacket kit SJ-FB provides a continuous tube from cable jacket to cable jacket with no seams, providing an excellent environmental seal and splice protection. It requires a shorter parking space than straight-line tubes, overcoming the problem of too little space in a ditch, manhole or vault.
Power utilities and industrial and commercial contractors using jacketed power cable will find many uses for this splice jacket. It is made of EPDM rubber that contains no chlorides or sulfurs. Four kit sizes cover an application range from 4 AWG, 15kV to sizes larger than 1,000 kcmil, 35kV.
The kit includes Scotch rubber mastic tape 2228, which provides an excellent environmental seal between the cable jacket and the foldback jacket tube. Mastic strips, also included in the kit, are used around the optional external ground conductor.
3M invented cold shrink splicing technology more than 30 years ago. Because the tube is applied by unwrapping and pulling a perforated core that supports the tube, installation presents fewer risks to installers than when using torches or tape to install a splice jacket.
