2、-M2L62-A TEMPERATURE MODIFIED POLYESTER AND EPOXY CEMENT INSULATED 1. SCOPE The material defined by this specification is soft or annealed round copper wire insulated with a single film of high temperature modified polyester resin having an epoxy cement overcoat. This is a Class “H“ rated insulation

3、. 2. APPLICATION This specification is released for a self bonding wire to be used for the air conditioning clutch coil windings. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production

4、 Materials (WSS-M99P1111-A). 3.1 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 ESH-M2L62-A 3.2 COLOR The color of the insulation shall be specified on the engineering drawing an

5、d/or release by the numerical suffix following the letter suffix of the material desired. The numerical color coding suffixes shall correspond to the following: 0 Black 4 Yellow 8 - Gray 1 Brown 5 Green 9 - White 2 Red 6 Blue 22 - Natural 3 Orange 7 - Violet Example: #14 gage ESH-M2L62-A3 shall desi

7、f 3 3.3 BARE WIRE The copper wire used as the base wire shall conform to ESF-M2L1-A, except as noted herein. 3.4 JOINTS Joints made in the insulated wire shall conform to ESF-M2L1-A and shall be covered with a high temperature modified polyester and epoxy cement film so as to be equally as well cove

8、red as other portions of the wire. 3.5 INSULATION COATING AND THICKNESS The wire shall be coated with a continuous insulating film of high temperature modified polyester having an epoxy cement overcoat, of such quality as to meet the requirements of this specification. The minimum increase in the di

9、ameter of the wire 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. 3.6 INT

10、ERMEDIATE 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. 3.7 INSULATION ADHESION No cracks in the (NEMA MW 1000, IEC 851) coating. 3.8 INSULATION FLEXIBILITY No cracks in the (NEMA MW 1000, IE

11、C 851) coating. 3.9 ELONGATION (NEMA MW 1000, IEC 851) The insulated wire shall meet the requirements of Table II. 3.10 SOFTNESS OF COPPER (NEMA MW 1000, IEC 851) The insulated wire shall meet the requirements of Table I. 3.11 UNIDIRECTIONAL SCRAPE RESISTANCE (NEMA MW 1000, IEC 851) The lowest “gram

12、s 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 specified in Table I. 3.12 DIELECTRIC TEST, min 2000 V/mil (79 (NEMA MW 1000, IEC 851) kV/mm) 3.1

13、3 CONTINUITY TEST (NEMA MW 1000, IEC 851) The insulated wire shall meet the requirements of Table I. ENGINEERING MATERIAL SPECIFICATIONESH-M2L62-APrinted copies are uncontrolled Copyright 2003, Ford Global Technologies, Inc. Page 3 of 3 3.14 HEAT SHOCK A sample of coated wire, prepared in accordance

14、 with para 3.8, shall be placed in an oven at 175 +/- 2 C for 1 h. No cracks in the coating shall be visible on size 4 to 40 Awg, when examined with 6X to 10X magnification. 3.15 THERMOPLASTIC FLOW, min 260 C (NEMA MW 1000, IEC 851) 3.16 THERMOPLASTIC FLOW - INCREASING PRESSURE 10 psi (69 kPa) (Size

15、s 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. The assembly is then positioned directly below the air cylinder on the test fixtur

16、e, which is mounted in a pre-heated oven, set at a temperature of 200 +/- 2 C. The assembly shall be allowed to soak in the pre-heated oven for at least 5 min and no more than 10 min after the thermometer indicates the oven has recovered its heat. At the end of this time the cylinder shall be lowere

17、d and the gage pressure set for 3 psi (21 kPa). After 30 s, the gage pressure is increased to 4 psi (28 kPa) and is thereafter increased 1 psi (7 kPa) pressure every 30 s until failure. The gage pressure when the signaling device sounds shall be recorded as the failure point. A minimum of 6 tests sh

18、all be run for each sample to determine average value. 3.17 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.
