2、 Technologies, Inc. Page 1 of 3 COPPER WIRE, SOFT OR ANNEALED ROUND - HEAVY ESF-M2L65-A HIGH TEMPERATURE MODIFIED POLYESTER AND POLYAMIDE INSULATED 1. SCOPE The material defined by this specification is soft or annealed round copper wire insulated with a heavy film of high temperature modified polye

3、ster resin having a polyamide overcoat. This is a Class “H“ rated insulation. 2. APPLICATION This specification was released originally for material used for the armature winding on the windshield wiper motors. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and

4、 part producers must conform to the Companys Standard Requirements 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-M2L65-A. 3.5

5、COLOR The color of the soft or annealed round copper wire insulated with a heavy film of high temperature modified polyester resin having a polyamide overcoat shall be specified on the engineering drawing. 3.6 BARE WIRE The copper wire used as the base wire shall conform to ESF-M2L1-A, except as not

6、ed herein. 3.7 JOINTS Joints made in the insulated wire shall conform to ESF-M2L1-A and shall be covered with a high temperature modified polyester and polyamide film so as to be equally as well covered as other portions of the wire.

Page 2 of 3 3.8 INSULATION COATING AND THICKNESS The wire shall be coated with a continuous insulating film of high temperature modified polyester having a polyamide overcoat, of such quality as to meet the requirements of this specification.

8、 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 H MW 27-C. The addition to the diameter of the bare wire due to the coating shall be determined utilizing the test method shown in specificat

9、ion NEMA MW 1000. 3.9 INTERMEDIATE SIZES 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 smaller Awg size. 3.10 INSULATION ADHESION No cracks in coating (NEMA MW 1000, IEC 851) 3.11 INSULATION FLEXIBILITY No cracks in

10、 coating (NEMA MW 1000, IEC 851) 3.12 ELONGATION (NEMA MW 1000, IEC 851) The insulated wire shall meet the requirements of NEMA Table. 3.13 INSULATION SOLUBILITY Insulation shall not (NEMA MW 1000, IEC 851) soften 3.14 SOFTNESS OF COPPER (NEMA MW 1000, IEC 851) The insulated wire shall meet the requ

11、irements of NEMA Table. 3.15 UNIDIRECTIONAL SCRAPE RESISTANCE (NEMA 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 ave

14、(NEMA MW 1000, IEC 851) 3.20 THERMOPLASTIC FLOW - INCREASING PRESSURE 69 kPa (Sizes 15 - 25 Awg, inclusive) Test Method: Two samples of the wire to be tested shall be cut and the ends stripped of insulation. The samples shall be fastened in the specimen holder and connected to the signaling device.

15、The assembly is then positioned directly below the air cylinder on the test fixture, which is mounted in a preheated oven, set at a temperature of 200 +/- 2 C. The assembly shall be allowed to soak in the preheated oven for at least 5 minutes and no more than 10 minutes after the thermometer indicat

16、es the oven has recovered its heat. At the end of this time, the cylinder shall be lowered and the gage pressure set for 21 kPa. After 30 s, the gage pressure is increased to 28 kPa and is thereafter increased 7 kPa pressure every 30 s until failure. The gage pressure when the signaling device sound

17、s shall be recorded as the failure point. A minimum of 6 tests shall be run for each sample to determine average value. 3.21 CONFORMITY WITH THIS SPECIFICATION In case of failure under any of the foregoing tests, two additional tests shall be made, and the wire shall be regarded as not meeting the requirements of this specification if the results of either of two additional tests are unsatisfactory.
