What is XLPE and PVC Insulations in Conductors ?

PVC is Polyvinyl Chloride and XLPE is cross linked Poly ethylene which is more chemically stable

XLPE cable can be used for Low, medium and high voltage applications. Conductor is insulated with XLPE which can withstand higher conductor temperature during normal and short circuit condition. It has better insulation value, lighter in weight and better current capacity with lesser  bending radius.Depending on application, it is selected and in areas which Is having moisture XLPE cables are preferred. It has lesser chance of mechanical damage and can be used for underground application with armouring and MDPE outersheathing.
