HEAT-SHRINKABLE WRAPAROUND SLEEVE (CRSM)

FOR CABLE REPAIR AND JOINT OUTER REJACKETING

• Wraparound sleeve used

for repair of damaged

cable jackets

and for rejacketing

of low voltage joints

• High mechanical strength

and impact resistance

• Excellent electrical

characteristics in order to

achieve requirements for

low voltage applications

• Halogen-free material

content, non-corrosive

and non-toxic smoke in

event of fire

• Compliant to RoHS

and REACH regulations

• UV Protection

KEY FEATURES

TE Connectivity’s (TE) Raychem CRSM wraparounds are a fast and

permanent cable repair and sealing system. The repair sleeve is quickly

fitted in place by means of its rail and channel closure. A moisture-proof,

insulating and tight-fitting repair is then obtained in one step by heating,

which makes the sleeve diameter shrink and the sealant coating melt and

flow into interstices.

Because of its heat-shrinkability, each CRSM size will fit several different

cable diameters. The sealant exhibits excellent bonding and sealing

characteristics to all materials commonly used in the various cable and

sheath constructions, such as plastic, rubber, lead and aluminium.

CRSM wraparounds are made of an abrasion and corrosion resistant

semi rigid material, and are a result of our extensive capability in

materials technology.

CRSM Raychem heat-shrinkable medium-wall wraparounds are designed

for insulation on low voltage cable accessories and applications, as well as

for repair, sealing and protection on medium voltage cables. The material

content is halogen-free and UV resistant.

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. TE’s Raychem wraparound CRSM is fast and easily installed

and has proven its long term reliability in harsh environmental conditions.
