Overview

TE’s Raychem Heat Shrink Wraparound Repair Sleeves fit easily onto the cable to repair the outer jacket and seal against moisture.
crsm

TE’s Raychem Wraparound Repair Sleeves (CRSM) are designed using heat shrink technology.  The closure system consists of a raised rail profile and a stainless steel channel that can be installed without any special tools. When heat is applied to the wraparound heat shrink cable jacket repair sleeves, they shrink tightly to the original smaller extruded diameter and to the cable shape. Their hot-melt sealant provides a reliable environmental seal. The wraparound repair sleeves are halogen-free and stabilized against UV radiation, which ensures long-term reliability in harsh environments.

The wraparound sleeves are mainly used as insulation, sealing, or as rejacketing material for 1000V power cables, as well as cable jacket repair for medium voltage power cables and may also be used as protection on various substrates. 

Our wraparound system is very easy to install and is particularly suitable when installation space is tight or difficult to reach.

FAQ

Frequently Asked Questions

Question: For which application can TE’s Raychem heat shrink wraparound repair sleeves be used?

Answer: Our Raychem wraparound sleeves can be used to repair the outer jacket of the cable and seal against moisture. The closure system consists of a raised rail profile and a stainless-steel channel.

 

Question: With what type of cable can I use the heat shrink wraparound sleeves?

Answer: Our heat shrink wraparound sleeves are for insulating, sealing or as rejacketing material for 1000V power cables, as well as cable jacket repair for medium voltage power cables. They may also be used as protection on various substrates, where installation space is tight or difficult to reach.

 

Question: What are the heat shrink wraparound sleeves made of? 

Answer: The wraparound repair sleeves are made of our Raychem heat shrink material. This specially-formulated medium-wall, cross-linked polyolefin shrinks to its original smaller extruded diameter when heat is applied. The heat shrink material is comprised of polymeric materials exposed to a high-energy electron beam that causes permanent cross-linking, or intermolecular joining, of adjacent molecules. Due to cross-linking, the heat shrink material loses its melting properties allowing it to be heated to temperatures beyond the crystalline melting point without melting. Above this temperature, heat shrink can be expanded and formed in shapes that will remain in position while the temperature decreases below the crystalline melting point again.

When properly installed our Raychem heat-shrinkable repair sleeves are long-lasting products that will help you improve your grid connectivity and reliability for decades.
