XLPE Power Cable
Underground MV/HV insulation
Three phase conductors are each wrapped in a semiconducting screen, a thick XLPE dielectric, another screen, then a copper wire shield, water-blocking tapes, steel-tape armour and an HDPE jacket. Cross-linking the polyethylene makes it thermoset — it doesn’t soften under fault-current heating.
