Foreword

GB/T 7673 "Paper covered wires" is divided into five parts. --- Part 1. General requirements; --- Part 2. Paper covered round wire; --- Part 3. Paper covered flat copper wire; --- Part 4. Paper insulated wire; --- Part 5. paper-insulated stranded wire. This section GB/T 37673 Part of. The partial modification of the use of IEC 60317-27.1998 "product standards of winding wires Part 27. Paper covered flat copper wire," and No. 1 Amendments (in English). This section according to IEC 60317-27.1998 redrafted. This section lists the reg number and IEC 60317-27 in Appendix A. 1998 reg control list numbered. Taking into account China's national conditions, this part of the part made some changes related to technical differences have been incorporated into the body and they are involved The terms of the margin with a single vertical line identification, and in Appendix B gives a list of these technical differences and the reasons for reference. This section also made the following editorial changes. --- "This standard" be replaced by "this section"; --- Remove the IEC 60317-27.1998 Foreword; --- Remove the IEC 60317-27.1998 specified in the chapter, "not applicable" technical requirements; --- Because our products represent a method has been implemented for many years, except in accordance with the provisions of this section need to adopt IEC 60317-27 specified yield Product representation, the product can also be used representation GB/T 7673.1 regulations; --- In GB/T 7673.1, the "Definitions, test methods General" content and IEC 60317-27 description in Chapter 3 a completely Cause, and adds to the appearance of the required provisions (IEC 60317 are other parts of the winding line of products for appearance of the requirements of the regulations) Part 3 direct reference to GB/T 7673.1 same provisions of Chapter 3; --- For ease of use, increasing the size specifications prescribed in Table 1, Table 2, Table 3; --- Validation provides resilience assessment indicators (IEC 60317-27 are under consideration); --- Increased acceptance rules, consistent with GB/T 7673 in other parts. This Part replaces GB/T 7673.3-1987 "Paper covered wires - Part 3. Paper covered flat winding wires." This section of the main changes compared 7673.3-1987 GB/T as follows. --- According to IEC 60317-27.1998 supplementary part of the definition (edition 3.1); --- Cancel the provisions of paper covered aluminum flat wire, consistent with IEC 60317-27 (Chapter 3 of the 1987 edition); --- Due to differences in the number of layers and the thickness of the insulating paper, the abolition of the uniform bending times the diameter of the provisions, in order to bend performance requirements When the provisions negotiated by both parties (the 1987 version of Chapter 5, Chapter 8 of this edition); --- Insulation thickness to the provisions negotiated by both parties (the 1987 version of Chapter 5 of this edition 4.4); --- More substantial reduced insulation thickness deviation (1987 edition Chapter 5, edition 4.4). This section of the Appendix A, Appendix B is an informative annex. This part is proposed by the China Electrical Equipment Industrial Association. This part of the National Standardization Technical Committee Wire and Cable (SAC/TC213) centralized. This part of the unit responsible for drafting. Shanghai Electric Cable Research Institute.
