3M 7000031475 Heat Shrink Cable Sleeve 1kv 3/0-400 Kcmil

Product Description

The 3M 7000031475 is a heavy-wall heat shrink cable sleeve designed for electrical splices, connections, and terminations up to 1 kV. Constructed from cross-linked polyolefin with a factory-applied internal adhesive and sealant, this sleeve delivers both mechanical and environmental protection once installed. It is rated for conductors ranging from 3/0 AWG through 400 kcmil and comes in a 12-inch cut-to-length format. The fast-shrink characteristic speeds up installation, while the heavy-wall construction provides high split resistance. UL Listed 486D for 600V (File E102356) and carries a CSA rating, making it suitable for listed electrical work.

This cable sleeve is used in residential and commercial electrical applications wherever a durable, moisture-resistant protection layer is required at splice points, joints, or terminations. Electricians install it on medium-voltage and low-voltage cable runs in conduit, tray, or direct-burial scenarios where conductor sizes fall in the 3/0 AWG to 400 kcmil range. The 12-inch length provides enough material for standard splice coverage or can be trimmed to suit the application.

Key Features

• Cross-linked polyolefin construction offers high split resistance and long-term durability
• Factory-applied internal adhesive and sealant creates a moisture and environmental seal on shrink
• Fast-shrink design reduces installation time in the field
• Rated to 1 kV, UL Listed 486D for 600V, CSA rated
• Compatible with conductor range 3/0 AWG through 400 kcmil
• Cut-to-length 12-inch sleeve provides installation flexibility

Compatibility

Designed for use with conductors sized 3/0 AWG through 400 kcmil in splicing, termination, and connection applications rated up to 1 kV.

Installation Notes

Installation is performed by licensed electricians in accordance with NEC requirements. De-energize and lock out the circuit completely before working on any splice or termination. Apply heat evenly along the sleeve using an appropriate heat gun, working from the center outward to prevent air pockets and ensure full adhesive flow. Do not use open flame as an alternative to a calibrated heat gun, as uneven heat can compromise the sealant and sleeve integrity.
