Aging mechanisms of two polymeric insulation materials that are used widely in nuclear power plant low-voltage cables; cross-linked polyethylene (XLPE) and ethylene propylene rubber/ethylene propylene diene terpolymer (EPR/EPDM), are reviewed. A summary of various nondestructive methods suitable for evaluation of cable insulation is given. A capacitive sensor capable of making local nondestruct...

This paper focuses on studying the improvement in the performance of Ethylene Propylene Diene Monomer (EPDM) which is used as outdoor high voltage insulating material by adding ATH filler. The study undertakes an investigation of the dry band arcing characteristics of the composite under un – aging condition. Also the dry band arcing characteristics of the composite have been studied under the ...

C5F10O has been widely studied as a promising environmentally friendly substitute to SF6 in power equipment. Up now, the gas insulated equipment developed still uses same sealing materials insulation However, whether these are chronically compatible with always fundamental problem that perplexes industry and academia. In this study, thermally accelerated aging experiment on four rubber contacte...
