ABSTRACT:
This invention relates to a method for preventing transport of fluids--such as water and/or gas--through a joint between at least two insulated cable conductors (1,2;21,22,23). The method includes provision of a jointing ferrule (3) for insertion of the conductor ends into the ferrule and making required electrical contacts, --and provision of a molded sheath (8) of insulation material over the joint in sealed contact with the conductor insulation. The ferrule is precovered with a coating containing EEA copolymer to obtain improved adhesion between the ferrule and the insulation sheath. The mold material must be compatible with--and preferably of the same material--as the conductor insulation.
