 LT-XLPE Cables have a higher conductor rating i.e. "90°C as compared 70°C of PVC and hence higher current rating.Maximum temperature limit under Short Circuit conditions for LT-XLPE Cables is 250°C as against 160"C for PVC Cables. Hence, LT-XLPE Cables have higher Short Circuit rating.LT-XLPE Cables have higher emergency overload capacity than PVC Cables ( upto 60%).LT-XLPE Cables have longer life as compared to conventional PVC Cables.Tensile Strength for LT-XLPE Cables is 1.9 Kg/mm2 as against 1.25 - 2.5 Kg/mm2 for PVC Cables.Elongation (%) in LT-XLPE Cables is 300-500 as compared to 200-400 in PVC Cables.LT-XLPE Cables have high corrosion resistance in polluted atmosphere as compared to PVC Cables.LT-XLPE Cables have better properties of resistance to chemical and corrosive gases.LT-XLPE Cables have better properties to withstand vibrations, hot impacts.Dielectric strength (KV/mm) for LT-XLPE Cables is 40-50 as compared to 20-35 for PVC Cables.The moisture resistance of LT-XLPE Cables is nearly 100 times that of PVC.LT-XLPE Cables have low Installation cost because of light weight, dimensions and are far more flexible.Insulation resistance of LT-XLPE Cables is very high as compared to PVC (as high as 1000 times).LT-XLPE Cables are ideal for transmission and distribution of power.Jointing of LT-XLPE Cables is easier and quicker.Low temperature Brittleness Degree 0C for LT-J XLPE Cables is-90 against-15 for PVC Cables.
