2、 2002, Ford Global Technologies, Inc. COPPER WIRE, SOFT OR ANNEALED ROUND, SINGLE ESF-M2L53-A ESTER-IMIDE INSULATED (SOLDERABLE) 1. SCOPE The material defined by this specification is a soft or annealed round copper wire insulated with a single film of solderable ester-imide resin of Class 155 therm

3、al rating. 2. APPLICATION This specification was released originally for windings on alternator rotor coils. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1

4、111-A). 3.2 WIRE SIZE SPECIFICATION The wire size shall be specified on the engineering drawing and/or release according to the American Wire Gage number desired. 3.3 COLOR The color of the solderable ester-imide film shall be specified on the engineering drawing. 3.4 BARE WIRE The copper wire used

5、as a base for the coated wire shall conform to ESF-M2L1-A, except as noted herein. 3.5 JOINTS Joints made in the insulated wire shall conform to ESF-M2L1-A and shall be covered with an ester-imide film so as to be equally as well covered as other portions of the wire.

6、ION ESF-M2L53-A Page 2 of 3 Copyright 2002, Ford Global Technologies, Inc. 3.6 INSULATION COATING AND THICKNESS The wire shall be coated with a continuous insulating film of ester-imide, of such quality as to meet the requirements of this specification. The minimum increase in the diameter of the wi

7、re due to the insulating film and the maximum overall diameter shall be as shown in Table I of specification ESF-M2L2-A. The addition to the diameter of the bare wire due to the coating shall be determined utilizing the test method shown in specification ESF-M2L2-A, para 3.4. 3.7 INTERMEDIATE SIZES

8、For wire sizes between the American Wire Gage sizes, the increase in diameter due to the coating shall be the same as for the next larger AWG size, and the test values shall be the same as for the next smaller AWG size. 3.8 INSULATION ADHESION No cracks in the coating (NEMA MW1000, para 3.1.1.1) 3.9
