3M 7000149319 Heat Shrink Cable Sleeve 1kv 250-750 Kcmil 48in

Product Description

The 3M 7000149319 is a heavy-wall heat shrink cable sleeve rated for 1 kV applications, designed to provide insulation, environmental sealing, and mechanical protection on medium-voltage power cables. 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.

This 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.

Key Features

• Rated for 1 kV service — suitable for low-voltage power distribution cable work
• Expanded inner diameter of 2.00 inches allows easy placement over large conductors
• Recovered inner diameter of 0.65 inches provides a tight, secure fit after shrinking
• Accepts cable sizes from 250 to 750 kcmil
• 48-inch sleeve length accommodates extended splice and transition zones
• Sold in a box of 5 pieces — minimum order quantity of 5

Compatibility

Designed 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.

Installation Notes

Installation 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.
