Superabsorbent polymers (SAP) are commonly used to protect underground power cables from water penetration and can be applied in various forms to different sections of the cable including:
- Within the stranded conductor
- Over the stranded conductor, under the conductor shield
- Over the insulation, under the concentric neutrals or metallic shield
- Over the metallic shield, under the outer sheath
