The XLPE insulated heavy duty cables were introduced worldwide in mid sixties. These cables have overcome the limitations of PVC Insulated Cables such as thermal degradation, poor moisture resistant and thermoplastic in nature. The advantages of XLPE Insulated cables in comparison to PVC insulated cables are as under:
Features and benefits
A. Technical Advantages :
- Higher current rating, higher Short Circuit Rating Approx 1.2 times that of PVC.
- Thermosetting in nature.
- Higher insulation resistance 1000 times 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 90C and short circuit temperature 250C.
B. Commercial Advantages:
- 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.
