3M™ 8420 Cold Shrink Connector Insulator is an open-ended, tubular sleeve that provides ozone, acids and alkalis resistance. This environmental sealing insulator offers primary electrical insulation for 1 kV-rated applications. The tough, durable, EPDM rubber construction makes the insulator withstand operating temperatures of -40 to 194 degrees F (-40 to 90 degrees C).
Accommodates 2/0 AWG to 250 kcmil conductor sizes
Withstands temperatures of -40 to 194 degrees F (-40 to 90 degrees C)
Suitable for insulating secondary splices, direct-buried or submersible and dig-in repairs
Insulates cable or connectors within a diameter range of 0.55 - 1.18 in (13,9 - 30,1 mm)
Simple installation which requires no tools
Made of EPDM rubber which contains no chlorides or sulfur
Specially designed for primary insulation of solid dielectric insulated wires and cable splicing rated to 1000 volts
ANSI Certified and RoHS 2011/65/EU Compliant
Environmental sealing for communication and other non-electrical applications
3M™ 8420 Connector Insulator is designed for use on all solid dielectric insulated wires and cable splices. This cold shrink insulator offers moisture-tight sealing while maintaining its prolonged resiliency and pressure. It is ideal for insulating secondary splices, direct-buried or submersible, dig-in repairs and physical protection of high-voltage, air-insulated connectors or lugs. ANSI Certified and RoHS 2011/65/EU Compliant.
