Insulated electrical conductors and coils

Claim 1

A SELF-SUPPORTING ELECTRICAL COIL FABRICATED FROM AT LEAST ONE ELECTRICAL CONDUCTOR, SAID ELECTRICAL CONDUCTOR HAVING A COMPOSITE COATING COMPRISING A POLYESTER COMPRISING (1) FROM ABOUT 25 TO 56 EQUIVALENT PERCENT OF A LOWER DIALKYL ESTER OF A MEMBER SELECTED FROM THE CLASS CONSISTING OF ISOPHTHALIC ACID AND TEREPHALIC ACID AND MIXTURES TEREOF, (2) FROM ABOUT 15 TO ABOUT 46 EQUIVALENT PERCENT OF ETHYLENE GLYCOL, AND (3) FROM ABOUT 13 TO ABOUT 44 EQUIVALENT PERCENT SATURATED ALIPHATIC POLYHYDRIC ALCOHOL HAVIN AT LEAST THREE HYDROXYL GROUPS, SAID POLYESTER HAVING AN OVERCOATING OF A BF3 AMINE COMPLEX CURED EPOXY RESIN, SAID EPOXY RESIN HAVING AN UNCURED VISCOSITY OF AT LEAST 40,000 CENTIPOISES AT 25*C.

Claim 2

A METHOD OF MAKING A SELF-SUPPORTING ELECTRICAL COIL WHICH COMPRISES WINDING SAID COIL FROM AN ELECTRICAL CONDUCTOR COATED WITH A POLYESTER COMPRISING (1) FROM ABOUT 25 TO 56 EQUIVALENT PERCENT OF A LOWER DIALKYL ESTER OF A MEMBER SELECTED FROM THE CLASS CONSISTIGN OF ISOPHTHALIC ACID AND TEREPHTHALIC ACID AND MIXTURES THEROF, (2) FROM ABOUT 15 TO ABOUT 46 EQUIVALENT PERCENT OF ETHYLENE GLYCOL, AND (3) FROM ABOUT 13 TO 44 EQUIVALENT PERCENT SATURTED ALIPHATIC POLYHYDRIC HAVING AT LEAST THREE HYDROXYL GROUPS, SAID POLYESTER HAVING AN OVERCOATING OF A BF3 AMINE COMPLEX CURABLE EPOXY RESIN, SAID EPOXY RESIN HAVING A VISCOSITY OF GREATER THAN 40,000 CENTIPOISES AT 25*C., SAID ELECTRICAL CONDUCTOR AND ITS COATING BEING AT A TEMPERATURE OF FROM ABOUT 40*C. TO 50*CD. DURING THE WINDING OF SAID COIL.
