Low Voltage Cross Linked Polyethylene Cables

Main Features

LT-XLPE cables are manufactured as per IS: 7098/ part1 suitable for continuous conductor temperature of 90c and short circuit 250c. ‘DYNAMIC’ LT-XLPE cables have excellent Electrical, mechanical and Thermal properties, surpassing those of conventional polymeric dielectrics . The superior properties of XLPE have led to lower insulation thickness, high current capacity, reduced weight and dimension. ‘DYNAMIC’ LT-XLPE Cable is the economic solution for low tension power distribution with high efficiency and total reliability.

Application

Power station, industrial units, projects and power transmission and distributions.

Advantages

LV-XLPE Cables have longer life as compared to conventional PVC Cables.

  • LV-XLPE Cables have a higher conductor temperature rating i.e. 90°C against 70°C PVC Cables.
  • LV-XLPE Cables have a higher emergency Overload capacity 130°C.
  • Max. Temperature limit under short circuit conditions for LV-XLPE Cables is 250°C against 160°C PVC Cables. Hence XLPE Cables have higher short Circuit Rating.
  • Insulation Resistance of LV-XLPE Cable is excellent & superior to identical PVC Cables.
  • LV-XLPE Cables have high corrosion resistance in polluted atmosphere.
  • LV-XLPE Cables have better properties of resistance to chemical and corrosive gases.
  • LV-XLPE Cables have low installation cost because of light weight dimensions and are far more flexible.
  • LV-XLPE Cables have better properties to withstand vibrations, hot impacts.
  • Jointing of LV-XLPE Cables is easier and quicker.
