Correctly fitted cable joint boxes, shells or moulds filled with mixed cold pour compound ensure reliable and water resistant cable joints which should withstand normal service and have an expected life cycle similar to that of the cable.

A key factor in ensuring effective water resistant cable joints is the cable sheath preparation by the LV jointer. Cable sheaths should be clean and well abraded by abrasive cloth or a coarse rasp to enable the cold pour cable jointing compound to bond to the cable jacket polymer.

Cable jointing tools used for sheath abrasion must be kept clean as any contamination of the actual cable sheath by oil or grease will prevent bonding and allow water moisture to ingress into the cable joint and lead to early joint kit failure.

Happy Jointing !
