3M Cold Shrink Quick Insulator QI 18/57-325 provides a quick solution for a wide range of cable sizes. It combines the environmental seal of mastic with the reliability of 3M's field-proven cold shrink technology. Each cold shrink tube has factory-installed mastic rings in each to provide added protection and range taking capability. Fits cable size range of 250 kcmil - 1250 kcmil. QI series insulators are easily installed by hand with no tools. They seal tightly with excellent wet electrical properties and are tested to requirements of ANSI C119.1. They are recommended for such applications as secondary inline splices, especially in tight spaces or on cable racks, with imperfect or scarred cable jackets, and for splices in which the cable can only be removed from one side. Also recommended for dig-in and sheath repair splices, street lighting, sealing connections or switchgear, transition connectors and set-screw or oversized connectors, and for retrofitting and repairing cable leads for secondary transformers.
