3M™ Cold Shrink Insulator WF Series is UL listed for direct bury and submersible applications in fresh or salt water environments for cable rated up to 2000 volts. The thick wall, open-ended, tubular, rubber sleeves are factory expanded and assembled onto a removable core. The core is removed after the tube has been positioned over an inline connection, terminal lug, etc., allowing the tube to shrink and form a water-resistant seal. The insulating tube is made of EPDM rubber.
3M has over 40 years of lab-tested and industry-proven results demonstrating the reliability of cold shrink technology. 3M™ Cold Shrink Quick Insulator WF Series and the other products in the cold shrink family are engineered with specially formulated materials that deliver a durable environmental seal and insulation. Six diameter sizes can accommodate cables up to 2000 volts, ranging from 4 AWG to 2000 kcmil for both copper and 4 AWG to 1500 kcmil for aluminum conductors. For applications with high UV exposure or where visual inspection isn't feasible, it is recommended to overwrap the tubing with Scotch® Super 33+™ Vinyl Electrical Tape or Scotch® Self-Fusing Silicone Rubber Electrical Tape 70.
