Drafting:
This document replaces GB/T 3428-2012 "Galvanized steel wire for overhead stranded conductors": Compared with GB/T 3428-2012, in addition to structural adjustments and
In addition to editorial changes, the main technical changes are as follows:
--- The model and representation method have been changed (see Chapter 4, Appendix C of the:2012 edition);
--- Changed the material requirements (see Chapter 5, Chapter 3 of the:2012 edition);
--- Changed the elongation requirements for grade 2 and grade 3 strength zinc-coated steel wires, and changed the 1% elongation requirements for grade 4 and grade 5 strength zinc-coated steel wires:
Long-term stress and tensile strength requirements (see 6:2, Chapter 6 of the:2012 edition);
--- Added grade 6, 7 and 8 strength zinc-coated steel wire and its performance requirements (see Chapter 6);
--- Added zinc-aluminum alloy coated steel wire and its performance requirements (see Chapter 6);
--- Added coating uniformity requirements and test methods (see 6:4:4 and 7:7:4);
--- Added inspection rules (see Chapter 8);
--- Added packaging and marking (see Chapter 9);
--- Added the method for determining the aluminum content in zinc-aluminum alloy coating (see Appendix A);
--- Deleted the gas volume method and weight method used to determine the quality of the zinc coating (see Appendix A and Appendix B of the:2012 edition):
