CABLE JOINT

摘要

An electric cable joint is enclosed within a heat shrinkable sleeve (40). The joint region is sealed against the ingress of moisture by a material that (a) comprises a non-crystalline polymer whose glass transition temperature is less than about -40 DEG C; (b) has a viscosity, measured at a shear rate of 0.02 sec<-1> and at a temperature of about 45 DEG C, that is less than about 10<6> Pa-sec; (c) has a viscosity, measured at a shear rate of 0.02 sec<-1> and at a temperature of about 95 DEG C, that is greater than about 10<3> Pa-sec, and (d) has a minimum tack value of about 140 gm/cm<2>.
