A kit comprising materials for protecting splices of electrical cables. Such splices as must be maintained underground between cables used in providing cathodic protection against corrosion to buried pipelines. The kit contains (a) a malleable butyl rubber composition having good low-temperature brittleness and exhibiting some cold flow characteristics, (b) a restraining fabric impregnated with a curable resin such as moisture-curable polyurethane which is characterized by good shelf life and a controlled curing speed when subjected to moisture. The invention also relates to the novel protected spliced structures which are formed by use of the kit material. |
