TE Connectivity’s (TE) Raychem CNSM heat-shrinkable heavy-wall wraparound is designed for sealing and outer protection on Low and Medium voltage cables and accessories. The sealant exhibits excellent bonding and sealing characteristics to all materials commonly used in the various cable and sheath constructions. CNSM is made of an abrasion and corrosion resistant semi-rigid material, and is a result of our extensive capability in materials technology.
The CNSM wraparound sleeves are suitable for repair of all types of unpressurised cable types, aerial, buried or ducted, with polyethylene, rubber or metal jackets. The hotmelt adhesive coated on the sleeve ensures a permanent reliable watertight seal. The excellent split resistance of the composite structure offers superior resistance to mechanical abuse during and after the installation. The outer surface of the wraparounds is treated with a temperature-indicating system to facilitate uniform heating during installation. In addition, white lines are painted on the flat side of the rails which become visible through the channel openings as installation is completed. The sleeve has a flap which is designed to seal longitudinal seam during installation.
Shelf-life restrictions usually associated with tapes or resins or cold-applied products do not apply and the completed installation may be taken into service at once. Raychem wraparound CNSM is fast and easily installed and has proven its long term reliability in harsh environmental conditions.
