  • Low and medium voltage cable joint filled with cold thermosetting resin and kit for the deployment thereof
    Patent number: 9771447
    Abstract: A joint for electric power cable, preferably operating at low and medium voltage, filled with a resin obtained in situ by contemporaneously cold setting a composition containing a (meth)acrylate ester of an alkanol having from 6 to 20 carbon atoms with a curing agent acting also as a tackifying agent and selected from the group consisting of a urethaneacrylate and an epoxylacrylate oligomer having a functionality from 1 to 6 in amounts ranging from 0.1 parts to 10 parts by weight per 100 parts by weight of the methacrylate ester. A kit for preparing a cable joint includes the joint and the composition for preparing the cured resin. The resin contained in the joint does not exhibit cold flow and therefore does not flow from the cable joint.
