XLPE
ARMOURED & UNARMOURED CABLES
Application:
These cables are designed for general use, including underground burial, where they are not likely to suffer mechanical damage. They have a molecular structure that allows them to bond with a strong resistance to deformation even at high temperature.
An important advantage of the insulation for medium and high voltage cables is its low dielectric loss. The dielectric loss factor is approximately one decimal power less than that of paper insulated cables and approximately two decimal powers less than that of PVC insulated cables.
