Influence of ageing and water treeing to degradation of XLPE insulation

Abstract

XLPE is modern material widely used as insulation material for power cables. Many studies and experiments show a significant infulence of ageing and water treeing to degradation of XLPE insulation. This article deals with a short review about XLPE and processes of ageing and water treeing in XLPE cable insulation. These processes, together with a crosslinking and amount of peroxide and antioxidants affect to quality and properties of XLPE insulation.
