R420 Series

RUNLIN™ Cold Shrink Connector Insulators R420 Series

The RUNLIN™ R420 Series (similar as 3M Part NO. 8420 Series ) Cold Shrink Connector Insulators R440 Series 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 silicone rubber which does not contain 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.

Applications

 Primary electrical insulation for all solid dielectric (rubber and plastic) insulated wire and cable splicing rated up to 1000 volts
 Direct burial and submersible
 For indoor and outdoor use
 Physical protection and moisture sealing for air-insulated connectors and lugs such as spacer cable and lug connections to bus bar
 Insulation of secondary splices, copper or aluminum conductors
 Relocation of service
 Dig-in repairs
 Sheath repairs
 Environmental sealing for communication and other non-electrical applications
 Insulation of inline conductor transition connectors

Features

 Simple installation; requires no tools
 Accommodates a wide range of cable sizes
 No torches or heat required
 Good thermal stability
 Seals tight; retains its resiliency and pressure even after prolonged years of aging and exposure
 Excellent wet electrical properties
 Tough rubber formulation withstands backfilling
 Water-resistant; Meets the water seal requirements of ANSI C119.1
 No mastic or tape required to seal
 Resists acids and alkalis; resists ozone
 Operating temperature range: -40°F to 194°F (-40°C to 90°C)
