Material development approach matching to an injection moulding rejuvenation for cable insulation failure

Abstract

Abstract This paper aims to construct a material developing approach matching to an injection moulding rejuvenation technique for cable insulation failure. The work starts from a chemical composition testing to the cable original insulation material. The applied composition should be determined by considerations of property requirements, including insulation, mechanical behaviour and environmental adaptability. In addition, a stable and standard manufacture technology should be groped to assure having a stable repair quality. Finally, proper material should be verified by testing for meeting normal the cable insulation requirements. By the above approach, typical material development is performed and the results by a code-based insulation property testing reveal the present approach has successfully been applied to develop a proper material matching to injection moulding rejuvenation technique for cable insulation failure.
