If SureSeal cable is damaged, or cut completely through on one end, resulting in a failure, will it seal itself causing the fault locating device difficulty in determining where the fault is located?
In the case of a partial cut in the SureSeal insulation, there is a high chance that the visco-elastic sealant will cover over the cut area, and the user will never know the cut occurred. However, in the case of a cut that severs the conductor, such as a dig-in, the sealant quantity is not sufficient to totally seal the ends. While some sealant will partially close the cut, the exposed conductor will, most likely, still be in contact with the earth, making fault locating easier. However, if difficulty is experienced in locating the fault, the sealant is designed with a lower dielectric strength than the polyethylene insulation, so thumping or other high voltage location techniques will breakdown the sealant at the damaged site and not cause damage to the intact cable.
