The information contained in this publication has been reviewed by all suppliers and refurbishers of plastic spools/reels known at the time of publication. The issuance or existence of this Standards Publication does not, in a
21、ny respect, prevent or restrict any member or non-member of NEMA from supplying customers with refurbished magnet wire spools/reels not in conformance with its contents. This Standards Publication was been developed by the NEMA Magnet Wire Section, which periodically reviews it for any revisions nec
22、essary to keep it up to date with changes in technology. Comments or proposed revisions are welcomed and should be submitted to: Vice President, Engineering National Electrical Manufacturers Association 1300 North 17th Street, Suite 1847 Rosslyn, VA 22209 This Standards Publication was developed by

Check flanges for broken ribs; d. on the surface of the barrel; and e. areas surrounding the arbor hole. 3.4 INSPECTION PROCEDURES CAUTION: All reels shall be at room
25、 temperature before placing any pressure on the flange when checking for cracks. Low temperatures reduce the flexibility of the reel. Applying pressure while the reel is in a brittle condition can result in damage to the reel and possible personal injury. Apply pressure down on either side of the re
26、el flange, then turn the reel 90 degrees ( revolution), and again press down on either side. When pressing down, check for cracks in the flange and for loose inserts. Turn the reel upside down and repeat procedure. Copyright 2003 by the National Electrical Manufacturers Association. MW 765-2003 Page
27、 5 Mechanical testing equipment may and should be employed as a substitute for the manual pressure checking process previously described, as they provide a more repeatable procedure by assuring a consistent pressure on the flanges. Pressure settings shall be of a value that is reached by mutual agre
28、ement between the inspection facility, the reel producer, and the wire manufacturer. Inspect the start ribs on the reel barrel for deformities that may cause wire snags. Remove rough areas with a knife, scraper, or sandpaper. Examine finger, tie-off, and arbor holes to assure they are smooth. 3.5 WO
29、BBLE For reels larger than 50 lbs., flanges shall be tested for wobble measuring 1/21/4 in. from the edge of the flange. Wobble shall be no more than 0.030 in. Copyright 2003 by the National Electrical Manufacturers Association. MW 765-2003 Page 6 Section 4 LARGE SIZE PLASTIC REELS 4.1 GENERAL This
30、section shall apply to the following large size plastic reels: Standard Nomenclature (Refer to MW 1000-2003 Appendix B Magnet Wire Packaging and Labeling) 250 pound - includes 15/16x12 and 24x6 325 pound 500 pound 550 pound 600 pound 650 pound 750 pound 1000 pound NOTEFor reels not listed above, the
31、 magnet wire manufacturer shall be contacted. 4.2 APPEARANCE AND CLEANLINESS The reel must be free of all grease, dirt, grime, etc. All wire, labels, and adhesive residue must be removed from the reel. 4.3 INSPECTION PROCEDURES CAUTION: All reels shall be at room temperature before placing any press
32、ure on the flange when checking for cracks. Low temperatures reduce the flexibility of the reel. Applying pressure while the reel is in a brittle condition can result in damage to the reel and possible personal injury. Apply pressure down on either side of the reel flange, then turn the reel 90 degr
33、ees ( revolution), and again press down on either side. When pressing down, check for cracks in the flange and for loose inserts. Turn the reel upside down and repeat procedure. Mechanical testing equipment may and should be employed as a substitute for the manual pressure checking process previousl
34、y described, as they provide a more repeatable procedure by assuring a consistent pressure on the flanges. Pressure settings shall be of a value that is reached by mutual agreement between the inspection facility, the reel producer and the wire manufacturer. 4.4 PHYSICAL CRITERIA 4.4.1 Flanges Flang
35、es must meet the following criteria: a. Cracks or severe stress lines are not acceptable in any part of the top or bottom flange. b. Chips are not acceptable in any part of the top or bottom flanges. c. All surfaces of both inside flange faces, the inside and outside radius of the top flange, and th
36、e inside radius of the bottom flange must be free of dents, gouges, and be smooth to the touch. On 24x6 reels, this applies to the inside face and the inside and outside radius of both flanges. Small gouges on all surfaces of the flange shall be sanded completely smooth. Copyright 2003 by the Nation
37、al Electrical Manufacturers Association. MW 765-2003 Page 7 NOTEExceptions: for a. through c. above: Some magnet wire producers may accept two small cracks or chips located in non-adjacent flange ribs. They may also accept, on straight flange reels, one chip located in the outside radius of the bott
38、om flange, if it is no greater than 1/2 inch long and no greater than 1/2 of the flange thickness. The magnet wire manufacturer shall be contacted for their specific exceptions. 4.4.2 Arbor Holes The interior of the arbor holes shall be free of cracks and chips, shall be smooth to the touch, and rou
39、nd, not deformed. 4.4.3 Barrel The barrel shall be smooth and free of cracks, chips, and stress lines. Start-up ribs on the barrel shall not have deformities which may cause wire snag. These shall be removed by means of a knife, scraper, or sandpaper. Small gouges on the surface of the barrel shall
40、be sanded smooth. 4.4.4 Eye Bolts The eye bolt used for lifting 1000-pound reels must be in place and tight (to be checked by finger tightness). Where the bolt is found missing or loose, the reel shall be rejected. Areas around any lifting holes shall be inspected for cracks or stress lines. If any
41、are found, the reel shall be rejected. 4.4.5 Bolts All bolts must be secure and seated in the square bolt head recess of the flange or in their cupped washer area. The bolt head seated in square recesses must not rotate the recess when inspected. Bolts must be tightened in a star rotation, not in a
42、circular rotation. All bolted reels shall have the bolts checked for tightness at each reclaiming cycle and shall meet the torque specifications established by the reel owner. 4.4.6 Wobble For reels larger than 50 lbs., flanges shall be tested for wobble measuring 1/21/4 in. from the edge of the fla
43、nge. Wobble shall be no more than 0.030 in. 4.5 REPLACEMENT PARTS CAUTION: Do not attempt to mix replacement parts from reels from different manufacturers. Due to differing construction methods, correct bolt torquing is not possible and may result in failure of the reel or possible personal injury.
44、Replace damaged parts of the reel. Used parts in good condition may be added with new parts to make a complete reel. When parts are replaced it is highly recommended that new bolts be added.
