A self-healing cable comprising a conductor and a water-swellable composition surrounding said conductor is disclosed. When the cable is damaged and water ingress reaches the water-swellable composition, the water-swellable composition expands and fills in any void, puncture or crack present, thus sealing the damage in the cable. In one embodiment, the water-swellable composition is formed from an admixture of a substantially non-water-swellable polymer and a water-swellable filler. In another embodiment, the water-swellable composition is formed from a water-swellable polymer.
