Foreword

This standard is equivalent to the use of IEC 60104-1987 "overhead wire with aluminum - magnesium - silicon alloy round" (English version). The main differences between this standard and IEC 60104-1987 are as follows. --- in accordance with the Chinese language used to modify some of the format; - the preamble of the international standard was removed; - the "normative reference document" in the preamble to adjust the international standard is 1.2; --- adjust the diameter range from 4.50mm to 4.80mm; --- Added Appendix A Aerial Strand with aluminum-magnesium-silicon alloy round wire product model design method. Appendix A to this standard is an informative appendix. This standard is proposed by China Electrical Equipment Industry Association. This standard by the National Wire and Cable Standardization Technical Committee (SAC/TC213) centralized. This standard is responsible for drafting units. Shanghai Cable Research Institute.

1 scope and normative reference documents

1.1 Scope This standard applies to two types of aluminum-magnesium-silicon alloy round wire with different mechanical and electrical properties for the production of overhead Electric wire. And the mechanical properties and electrical properties of aluminum-magnesium-silicon alloy round wire with diameter range of 1.50mm ~ 4.80mm are specified. These two models are LHA1 and LHA2, respectively. 1) corresponds to type A and type B as specified in IEC 60104. See Appendix A for product representation. 1.2 Normative references The terms of the following documents are hereby incorporated by reference into this standard. Whichever is the date of the reference file, which is followed by all (Not including corrigenda) or revisions are not applicable to this standard, however, encourage the parties to reach an agreement under this section to study Whether you can use the latest version of these files. For undated references, the latest edition applies to this standard. GB/T 3048.2-2007 Test methods for electrical performance of wire and cable - Part 2.

3 material

The alloy round wire should be made of heat-treated aluminum-magnesium-silicon alloy material, the composition should be with the LHA1 and LHA2 type of mechanical And electrical performance.

4 surface quality

The surface of the alloy round wire should be smooth and should not have any defects such as cracks, burrs, cracks, inclusions, etc. that are not commensurate with good merchandise.

5 Diameter and Diameter Tolerance

The nominal diameter of the alloy round wire (mm) is accurate to two digits after the decimal point. The difference between each measured value and the nominal value shall not be greater than that in Table 2 Column value. GB/T 23308-2009/IEC 60104. 1987 ......
