Cross Linking of Polyolefin Cable and Line Insulations by High Energy Radiation. Part I: Materials for Radiation Cross Linking

摘要

The general basic investigations served, on the one hand, for selection of polyolefins crosslinkable by radiation including the copolymers of ethylene and polyolefin elastomer blends, on the other hand for development of effective stabilizing systems against thermo-oxidative ageing and copper-catalized oxidation. At the same time the influence of crosslink-reinforcing coagents and fillers and pigments was studied. For the materials XLPE, EPR and EVA the optimization of compounds in a scope of production trials resulted in useful proposals for solutions for 1kV insulating compounds.
