3M Scotch 2151 Tape – Rubber Splicing Cable Jointing Tape

3M Scotch 2151 Tape - Rubber Splicing Cable Jointing Tape

3M Scotch 2151 Tape – Rubber Splicing Cable Jointing Tape

3M Scotch 2151 Tape is a conformable, self-fusing rubber electrical insulating tape, manufactured from ethylene-propylene rubber (EPR) based self amalgamating tape

Scotch 2151 Tape can be used as an insulation for low voltage applications as well as insulation for cable joints up to 69kV.

Rubber Splicing Cable Jointing Tape Features

  • High insulation properties
  • Excellent conformability
  • Excellent sealing properties
  • Excellent and fast self-bonding without blistering
  • 3M Scotch 2151 tape has excellent tensile strength and elongation allowing easy application

3M Scotch 2151 Tape – Applications

  • Primary electrical insulation for jointing cable from 600V to 69kV on all solid dielectric cables
  • Moisture sealing electrical connections.
  • End sealing high-voltage cables
  • Electrical insulation for splices and terminations

Installation Techniques

  • Scotch 2151 Tape should be applied in successive half lapped, level-wound layers until desired build-up is reached
  • To eliminate voids in critical areas, highly elongate 2151 Tape
  • Stretch tape in these critical areas just short of its breaking point – doing so will not alter its physical or electrical properties
  • In less critical areas, less elongation may be used – normally, 3M Scotch 2151 Tape is stretched to ¾ of its original width in these less critical areas
  • Always attempt to half-lap to produce a uniform build-up
  • When using 2151 Tape for jointing cables from 35kV to 69kV, always elongate the tape throughout the entire joint
