2、OPPER WIRE, SOFT OR ANNEALED ROUND, SINGLE ESF-M2L25-A POLYURETHANE AND NYLON INSULATED, SOLDERABLE NOT FOR NEW DESIGN 1. SCOPE The material defined by this specification is a soft or annealed round copper wire insulated with a single film of solderable baked synthetic polyurethane varnish having a

3、nylon overcoat. 2. APPLICATION This specification was released originally for material used for field windings on fractional horsepower motors. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements

4、For Production Materials (WSS-M99P1111-A). 3.4 WIRE SIZE SPECIFICATION The wire size shall be specified on the engineering drawing and/or release according to the American Wire Gage number desired. Example: #14 gage ESF-M2L25-A. 3.5 COLOR The color of single polyurethane and nylon insulation shall b

5、e specified on the engineering drawing. 3.6 BARE WIRE The copper wire used as a base for the polyurethane and nylon coated wire shall conform to ESF-M2L1-A, except as noted herein. 3.7 JOINTS Joints made in the polyurethane and nylon insulated wire shall conform to ESF-M2L1-A and shall be covered wi

6、th a polyurethane and nylon film so as to be equally as well covered as other portions of the wire. ENGINEERING MATERIAL SPECIFICATION ESF-M2L25-A Copyright 2014, Ford Global Technologies, Inc. Page 2 of 3 3.8 INSULATION COATING AND THICKNESS The wire shall be coated with a continuous insulating fil

7、m of polyurethane and nylon, of such quality as to meet the requirements of this specification. The minimum increase in the diameter of the wire due to the insulating film and the maximum overall diameter shall be as shown in NEMA MW 1000 Part 2, Table S-MW 28-C. The addition to the diameter of the

8、bare wire due to the polyurethane and nylon coating shall be determined utilizing the test method shown in NEMA MW 1000 Part 2, Table S-MW 28-C. 3.9 INTERMEDIATE SIZES For wire sizes between the American Wire Gage sizes, the increase in diameter due to the polyurethane and nylon coating shall be the

9、 same as for the next larger Awg size, and the test values shall be the same as for the next smaller Awg size. 3.10 INSULATION ADHESION No cracks in the (NEMA MW 1000, IEC 851) coating 3.11 INSULATION FLEXIBILITY No cracks in the (NEMA MW 1000, IEC 851) coating 3.12 INSULATION AGING No cracks in the

10、 (NEMA MW 1000, IEC 851, 125 +/- 3 C) coating 3.13 ELONGATION (NEMA MW 1000, IEC 851) The insulated wire shall meet the requirements of NEMA Table. 3.14 INSULATION SOLUBILITY Insulation shall (NEMA MW 1000, IEC 851) not soften 3.15 SOFTNESS OF COPPER (NEMA MW 1000, IEC 851) The insulated wire shall

11、meet the requirements of NEMA Table. 3.16 SCRAPE RESISTANCE Scrape resistance shall be measured in accordance with one of the following two methods: 3.16.1 Repeated Scrape Resistance, min (NEMA MW 1000, IEC 851, Table I) Average 20 strokes Single 10 strokes 3.16.2 Unidirectional Scrape Resistance (N

12、EMA MW 1000, IEC 851) The lowest “grams to fail“ load, representing failure of the insulating film, in any one of the three tests shall not be less than the minimum value and the average of the three tests shall not be less than the average value specified in Table I.
