Constructed from cross-linked polyolefin, the sleeve is highly split-resistant and fast-shrinking, enabling rapid installation in demanding electrical environments. It comes in a 48-inch cut-to-length format with a factory-applied adhesive sealant on the interior wall. The sealant flows during shrink to create a moisture-resistant mechanical seal around the conductor. Licensed electricians and utility splicing crews are the primary installers for this type of sleeve on medium-voltage and low-voltage conductor work.\u003c\/p\u003e\n\u003cp\u003eThis cable sleeve is suited for use on conductors ranging from 3\/0 AWG to 400 kcmil. It is appropriate for residential service entrance splices, commercial feeder connections, and industrial termination assemblies operating at or below 1 kV. The 48-inch length allows the installer to cut individual pieces to the required length, reducing waste on multi-conductor or varied-length jobs. The integrated adhesive sealant provides environmental protection against moisture and contaminants without requiring a separate mastic or tape wrap.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRated to 1 kV; UL Listed 486D for 600V (File Number E102356) with CSA certification\u003c\/li\u003e\n  \u003cli\u003eCross-linked polyolefin construction provides high split resistance and chemical durability\u003c\/li\u003e\n  \u003cli\u003eFactory-applied internal adhesive sealant creates a sealed, moisture-resistant barrier on shrink\u003c\/li\u003e\n  \u003cli\u003eFast-shrink characteristic reduces installation time compared to standard-wall sleeves\u003c\/li\u003e\n  \u003cli\u003eCut-to-length 48-inch sleeve accommodates multiple splice lengths from a single piece\u003c\/li\u003e\n  \u003cli\u003eFits conductors from 3\/0 AWG through 400 kcmil\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on copper and aluminum conductors from 3\/0 AWG to 400 kcmil in electrical splice, connection, and termination applications rated up to 1 kV.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed electrician. De-energize and lock out the circuit before beginning any splice or termination work, following NFPA 70E arc flash and lockout\/tagout procedures. Apply heat evenly along the sleeve using a calibrated heat gun, working from the center outward to prevent air entrapment under the wall. Do not use an open flame torch on polyolefin sleeves, as uneven or excessive heat can char the material and compromise the seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 1 kV\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUL Listing\u003c\/strong\u003e: UL 486D, 600V, File Number E102356\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertification\u003c\/strong\u003e: CSA Rated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConductor Range\u003c\/strong\u003e: 3\/0 AWG to 400 kcmil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 48 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWall Type\u003c\/strong\u003e: Heavy-wall\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cross-linked polyolefin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSealant\u003c\/strong\u003e: Factory-applied internal adhesive sealant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000149320\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345198383410,"sku":"7000149320","price":1537.14,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310535252.jpg?v=1782051399","url":"https:\/\/voomisupply.com\/products\/3m-7000149320-heat-shrink-cable-sleeve-1kv-48in","provider":"Voomi Supply","version":"1.0","type":"link"}
