The XLPE insulated heavy duty cables were introduce worldwide in mid sixties. These cables have overcome the limitation of PVC in mid sixties. These cables have overcome the limitations of PVC Insulated Cables such as thermal degradation, poor moisture resistant and thermoplastic in nature.
Higher current rating, higher Short Circuit Rating Approx 1.2times that of PVC. Thermosetting in nature.
Higher insulation resistance— 1000times more than PVC cables. Higher resistance to moisture.
Better Resistance to surge currents. Low Dielectric Losses.
Better resistance to chemicals. Longer service life.
Comparatively higher cable operation temperature 90°C and short circuit temperature 250°C.
Lower laying cost because of comparatively smaller diameter of cable and lighter weight. Lower installation charges as the diameter of cable is comparatively lesser with smaller bending radius, requiring less space requirement for laying of cables.
One size lower cable can be used as compared to PVC insulated cable. Density of XLPE is lower than PVC.
For longer cable length voltage drop shall be considered
