摘要
An insulated electrical member adapted for high voltage use is made by (1) covering a conducting member having a porous layer disposed thereon with a non-linear stress grading composition comprising cycloaliphatic epoxy resin, non-linear silicon carbide and an effective amount of curing agent, (2) curing the non-linear stress grading composition at up to about 130° C., (3) impregnating the porous layer with a reactive insulating resin composition containing polar components, such that the resin composition contacts the non-linear stress grading composition, and (4) heating the covered, impregnated electrical member to cure the insulating resin composition, where the non-linear stress grading composition after insulating resin cure is characterized as remaining adherent to the member.
