Part of the ITCSN-2000 series, this sleeve features an expanded inner diameter of 2.00 inches and a recovered inner diameter of 0.65 inches, accommodating cable sizes from 250 to 750 kcmil. Each sleeve is 48 inches in length and ships in a box of five pieces. Licensed electricians and cable splicers install this product during cable termination, repair, and transition work where a durable, shrink-to-fit protective layer is required.\u003c\/p\u003e\n\u003cp\u003eThis sleeve is suited for use in commercial and industrial electrical installations where 1 kV-rated cable protection is needed. Typical applications include cable splicing, end terminations, and bundling transitions on copper or aluminum conductors in the 250 to 750 kcmil range. The 48-inch length provides adequate coverage for extended splice zones or step-down transitions. Electricians working on power distribution feeders, industrial machinery wiring, and infrastructure cable runs will find this sleeve appropriate for demanding in-field conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRated for 1 kV service — suitable for low-voltage power distribution cable work\u003c\/li\u003e\n  \u003cli\u003eExpanded inner diameter of 2.00 inches allows easy placement over large conductors\u003c\/li\u003e\n  \u003cli\u003eRecovered inner diameter of 0.65 inches provides a tight, secure fit after shrinking\u003c\/li\u003e\n  \u003cli\u003eAccepts cable sizes from 250 to 750 kcmil\u003c\/li\u003e\n  \u003cli\u003e48-inch sleeve length accommodates extended splice and transition zones\u003c\/li\u003e\n  \u003cli\u003eSold in a box of 5 pieces — minimum order quantity of 5\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on copper and aluminum power cables ranging from 250 to 750 kcmil with an outer diameter that falls within the 2.00-inch expanded to 0.65-inch recovered range, consistent with 1 kV-class cable termination and splicing applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician following applicable NEC requirements for cable termination and splice protection. De-energize and verify the circuit is fully isolated before beginning any cable work. Use a calibrated heat source such as a propane or butane torch, working evenly along the sleeve to avoid scorching or uneven shrinkage. Do not energize the circuit until the sleeve has fully cooled and recovery is confirmed complete.\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\u003eCable Size Range\u003c\/strong\u003e: 250-750 kcmil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExpanded Inner Diameter\u003c\/strong\u003e: 2.00 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecovered Inner Diameter\u003c\/strong\u003e: 0.65 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 48 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity per Box\u003c\/strong\u003e: 5 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.45 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00054007089063\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: 7000149319\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343434219826,"sku":"7000149319","price":515.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310535262.jpg?v=1782021424","url":"https:\/\/voomisupply.com\/products\/3m-7000149319-heat-shrink-cable-sleeve-1kv-250-750-kcmil-48in","provider":"Voomi Supply","version":"1.0","type":"link"}
