Cable Sheath Repair

Nexans GT11 is a heat shrink wraparound cable sheath repair  to enable effective repair of damaged outer cable sheaths and jackets – Nexans GT11R is a fibre reinforced version of the GT11 suitable for cable joint outer sheath rebuilding on LV MV HV cable applications where space is at a premium or when parking the outer jacket tubing during jointing cables is difficult.

The cable repair sleeves feature a heat shrinkable cross-linked polyolefin sheath with closing hinge and hot-melting adhesive. The anti-corrosive stainless steel hinge allows sheath closing around the damaged section of cable in order to do fast cable reparation in LV MV HV sections even in environments with high pollution.
