Abstract:

This paper introduced the basic requirements of direct current (DC) cable insulation as well as the problems exi⁃sting in mechanical properties, aging resistance, insulation properties and thermal conductivity when using polypropylene as a raw material for DC cable insulation. The research progress in the copolymerization modification, nanoparticle modification, blend modification and graft modification of polypropylene was reviewed. The future research direction of polypropylene⁃based materials for DC cable insulation was prospected.

Key words: cable insulation, direct current transmission, polypropylene, nano?modification, space charge
