XLPE and EPR Cable Rejuvenation

XLPE and EPR cables suffer from insulation failure with time due to the formation of water trees. Water trees form in microscopic voids in the insulation. Over time and with electrical stresses, these voids grow in a tree-like form. Eventually, these larger and larger voids cause cable insulation failure. Because of the nature of the insulation materials, water trees are almost inevitable in polymeric cables.
