Short Description

3M™ Cold Shrink Connector Insulators 8420 and 8430 Series are designed using 3M’s proprietary cold shrink delivery system. Products are supplied prestretched on a removable core for efficiency and ease of installation. Removal of the core (unwinding) after positioning the splice allows the product to shrink into position forming a moisture-tight seal. The live memory action of the specially formulated EPDM material promotes a permanent, durable environmental seal and insulation.

Features

  • Simple installation, requires no tools and accommodates a wide range of cable sizes
  • Copper conductor with polyolefin foam
  • 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, no mastic or tape required to seal
  • Resists acids and alkalis, resists ozone
  • Primary electrical insulation for all solid dielectric (rubber and plastic) insulated wire and cable splicing rated up to 1000 volts
  • 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
  • -40 to 194 deg F temperature rating, 1 kV voltage rating
  • UniShield®, wire shield, non-shielded, tape shield cable
  • 12 in relaxed tube length, 8 in max connector length
  • 0.67 min cable dia for seal, 1.38 in max dia insulator cable or connector covers
  • 250 - 400 kcmil conductor size
  • 1 conductor, 250 kcmil, 400 kcmil, 300 kcmil, 350 kcmil conductor sizes
  • 10/Case
