AN INSULATED CONDUCTOR COMPRISING AN ELECTRICAL CONDUCTOR, AN INNER DIELECTRIC COATING OF A POLYESTER THERMOSET RESIN COVERING SAID CONDUCTOR AND AN OUTER DIELECTRIC COATING OF A THERMOSET RESIN COVERING SAID INNER COATING, SAID RESIN OF SAID OUTER COATING: EXHIBITING RESISTANCE TO HEAT SHOCK PRODUCED BY EXPOSURE TO A TEMPERATURE OF 175*C. FOR AT LEAST 2 HOURS; EXHIBITING RESISTINACE TO SOLVENT SHOCK PRODUCED BY BOILING IN XYLENE FOR AT LEAST 10 MINUTES; AND CHARACTERIZED BY FLEXIBILITY AFTER HEAT AGING AT 190* C. FOR AT LEAST ONE WEK; SAID OUTER COATING BEING RESIN WHICH IS A REACTION PRODUCT OF MATERIALS SELECTED FROM THE GROUP CONSISTING OF (A) 30% TO 80% BY WEIGHT OF A HIGH MOLECULAR WEIGHT POLYESTER OF A HIHYDRIC ALCOHOL WITH AN AROMATIC DICARBOXYLIC ACID, UP TO 50% BY WEIGHT OF AN EPOSXY RESIN, AND 0.1% TO 12% BY WEIGHT OF A CROSS-LINKING CATALYST, AND (B) 30% TO 80% OF A HIGH MOLECULAR WEIGHT POLYETER OF A DIHYDRIC ALCOHOL WITH AN AROMATIC DICARBOXYLIC ACID UP TO 60% BY WEIGHT OF A POLYESTER OF TEREPHTHALIC ACID AND A MIXTURE OF A GLYCOL AND A POLYHYDRIC ALCOHOL WITH AT LEAST 3 HYDROXYL GROUPS, AND 0.1% TO 12% BY WEIGHT OF A CROSS-LINKING CATALYST.
