3M Cold Shrink Connector

Insulators 8420 Series

Data Sheet

December 2012

Product Description
3M Cold Shrink Connector Insulators are open-ended, tubular, rubber sleeves which are factory expanded and assembled onto a removable core. The core is removed after the tube has been positioned for installation 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 which contains no chlorides or sulfur. Six diameter sizes will cover a range of cable up to 1000 volts for copper and aluminum conductors from 10 AWG through 1000 kcmil.

To extend the useful life of this product in applications which are continuously exposed to high levels of ultra-violet radiation, overwrap with Super 33+ Vinyl Tape or Self-Flushing silicone Rubber Tape
x Simple installation, requires no tools. x Accommodates a wide range of cable sizes. x No torches or heat required. Good thermal stability. x Seals tight, retains its resiliency and pressure even after prolonged years of aging and exposure. x Excellent wet electrical properties. x Improved, tougher rubber formulation to withstand backfilling. x Water-resistant. Meets the water seal requirements of ANSI C119.1. x No mastic or tape required to seal. x Resists acids and alkalies, resists ozone, resists fungus.
x Primary electrical insulation for all solid dielectric rubber and plastic insulated wire and cable splicing rated to 1000 volts.
x Direct burial or submersible. For indoor, outdoor. x Physical protection and moisture sealing for air-insulated connectors and lugs such as spacer
cable and lug connections to bus bar. x Insulation of secondary splices, copper or aluminum conductors. x Relocation of service. Dig-in repairs. x Sheath repairs. x Environmental sealing for communication and other non-electrical applications. x Insulation of inline conductor transition connectors see Figure
