3M™ Cold Shrink Insulator 8427-12 (OD 17.5-35.1 mm) 1kV, 10 EA/Case - 7000005943
3M™ Cold Shrink Connector Insulators 8420 and 8430 Series are EPDM, factory-expanded rubber tubes designed with cold shrink technology and loaded on a removable plastic core. To install the connection, position it over the inline connector, pull the loose tab on the plastic core while unwinding the core in a counterclockwise direction, allowing the ends of the tube to shrink and form a secure seal. Engineered for primary insulation of solid dielectric insulated wires and cable splices rated up to 1000 volts, the insulators can be used for indoor and outdoor applications to provide a water-resistant seal. They are easy to install by hand, requiring no additional tools or heating sources. Accommodating a variety of cable sizes, 3M™ Cold Shrink Connector Insulators 8420 and 8430 Series provide physical protection and environmental sealing for terminal lug barrels, conduit coupling, and conduit-to-cable breakouts. These insulators are ideal for direct burial or submersible applications involving communication and other non-electrical operations, such as dig-in and sheath repairs, and secondary splices for both copper and aluminum conductors. They can withstand an operating temperature range between -40 °F to 194 °F (-40 °C to 90 °C) and meet the water seal requirements of ANSI C119.1. When you need dependable insulating properties with long-lasting resiliency, look no further than 3M™ Cold Shrink Connector Insulators 8420 and 8430 Series.
