3M 7000138430 Heat Shrink Cable Repair Sleeve 1-35kv

Product Description

The 3M 7000138430 is a wraparound heat shrink cable repair sleeve rated for use on medium-voltage cable systems from 1 to 35 kV. It is designed to restore damaged cable sheaths and provide a durable, watertight seal over cable joints and splices. The inner wall is coated with hot melt adhesive that bonds directly to the cable surface when heat is applied, creating a moisture-resistant seal. A corrosion-proof metal closure clip secures the wraparound profile before shrinking. Licensed electricians and cable splicing technicians install this sleeve during cable sheath repair and joint assembly work on power distribution systems.

This sleeve is suited for medium-voltage underground and above-ground cable systems operating in the 1 to 35 kV range. It can be used to repair mechanically damaged cable sheaths, as an oversheath for cable joints, or as supplemental corrosion protection on undamaged cables. The wraparound design allows installation without access to a free cable end, making it practical for in-service repairs and mid-run joint work. It performs reliably in aggressive environments including buried, wet, and chemically exposed installations.

Key Features

• Rated for cable systems from 1 to 35 kV
• Hot melt adhesive inner wall creates a watertight, bonded seal when heat is applied
• Wraparound design installs without requiring a free cable end
• Corrosion-proof metal closure clip fully secures sleeve prior to shrinking
• Suitable for sheath repair, joint oversheathing, and corrosion protection on undamaged cables
• Performs in mechanically demanding and chemically aggressive environments

Compatibility

Designed as an OEM-style replacement and repair solution for medium-voltage cable systems rated 1 to 35 kV requiring sheath repair, joint protection, or supplemental corrosion protection.

Installation Notes

Installation is performed by licensed electricians or qualified cable splicing technicians in accordance with applicable NEC and utility work practices. De-energize and verify the absence of voltage on the cable before beginning any sheath repair work. Clean and dry the cable surface in the repair area before positioning the sleeve and securing the metal closure clip. Apply heat evenly along the sleeve using a propane or butane torch to achieve full shrinkage and adhesive flow without overheating any single section.
