ANSI/NEMA MW 1000-2015 Part 0, Page 3 2015 National Electrical Manufacturers Association FOREWORD ANSI/NEMA MW 1000-2015 supersedes NEMA MW 1000-2014 and all subsequent revision

14、s. It has been approved as an American National Standard. This standard is periodically reviewed by the NEMA Magnet Wire Section for revisions considered to be necessary to keep it up to date with changes in technology and regulations. See http:/www.nema.org/ Products/Pages/MW-1000.aspx for addition

15、al information. Proposed or recommended revisions should be submitted to: Senior Vice President, Operations National Electrical Manufacturers Association 1300 North 17th Street, Suite 900 Rosslyn, Virginia 22209 MW 1000 was developed by the Magnet Wire Section of NEMA, working closely with represent

16、atives of various industries that use magnet wire. At the time this edition was approved, the Magnet Wire Section had the following members: Alconex Specialty Products, Inc.

Fort Wayne, IN ANSI/NEMA MW 1000-2015 Part 0, Page 4 2015 National Electrical Manufacturers Association How to Use This Publication First, review Part 1 for general inf

18、ormation. Then in Part 2, locate the specification for the type of insulation and conductor of interest. Part 2 is arranged in numerical order as shown beginning on page 14. The dimensions for each Part 2 MW type are provided in Part 1, beginning with Table 1. The specification in Part 2 will indica

19、te the requirements to be met and will refer to the test procedures and corresponding test values to be attained in Part 3. Part 1 of this publication deals with information common to all types of magnet wire: ordering information, general material requirements, general test conditions, definitions,

20、 and manufacturing data in support of thermal rating. This part also includes dimensions with metric equivalents for all bare, minimum insulation increase, and overall dimensions for all Part 2 MW specification requirements. Part 2 consists of product specifications requirements (other than dimensio

21、ns) for magnet wire with different types of coatings and/or coverings. Insofar as possible, the product specifications are complete on one sheet, since they are arranged to include only one insulation or covering per sheet. The title on each sheet identifies the product. Example: MW 15-C, Polyvinyl

22、Acetal Round Copper Magnet Wire. MW 15-A covers the aluminum version of the same generic product. Part 3 contains the test procedures to be followed and corresponding tables of specific test values to be attained in determining compliance with the requirements given in Part 2. The requirements are c

23、onsolidated with the test procedures and testing parameters for a given property. An index of the main test paragraphs is provided, beginning on page 14, Part 3 Test Procedures, in the Table of Contents. Annex A provides a cross reference between test procedures in this standards publication and tho

24、se published by the American Society for Testing and Materials (ASTM). Annex B consists of definitions, requirements, and recommended test procedures for reusable magnet wire packaging, standardized dimensions for spools and reels, and formatting for the labeling of magnet wire products. Annex C pro

25、vides a cross reference between NEMA and IEC magnet wire specifications. Annex D provides the formulas for determining dimensional requirements of round film-insulated magnet wire and dielectric breakdown, as well as cross-sectional area and resistance calculations. Annex E provides the dimensional

26、criteria for ranges of sizes of rectangular bare, film, and fabric magnet wire products, setting the general rules and guidelines for various traditional yet non-standard rectangular magnet wire products. Annex F provides properties of selected refrigerants determined as suitable alternatives to ref

27、rigerant R22 in the Refrigerant Extraction Test, clause 3.55. Annex G provides recommended winding tensions for round copper and aluminum magnet wire to ensure that wire, as it is de-reeled, is not stretched beyond end user requirements. Annex H provides the test methods and requirements for fully i

28、nsulated winding wire (FIW) referenced in specification MW 85-C in Part 2.
