Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 17048-2009 "overhead strand with a hard aluminum wire", compared with the GB/T 17048-2009 main technical changes
as follows.
--- The scope of an increase of hard aluminum resistance level and cross-sectional shape (see Chapter 1,.2009 edition 1.1);
--- Increase the resistivity and temperature coefficient of resistance at 20 ℃ for different resistance grades of hard aluminum (see Chapter 3);
--- Increased the equivalent diameter and equivalent diameter of hard aluminum line deviation (see Chapter 6);
--- Increasing the mechanical properties of different types of hard aluminum round wire and hard aluminum wire (see 11.1);
--- Modify A.1 in Appendix A, "code" for the "type code", delete A.1.1 and A.1.2; modified aluminum round line representation
Act and examples, an increase of hard aluminum line representation and examples (see Appendix A,.2009 edition of Appendix A).
This standard uses redrafted Law Amendment uses "IEC 60889.1987" overhead stranded hard aluminum wire. "
This standard compared with IEC 60889.1987, there are more structural adjustments. Appendix B lists the standard and IEC 60889.
1987 reg number control list.
The technical differences between this standard and IEC 60889.1987 are as follows to meet the actual needs of China's power industry.
--- Chapter 1 increased the resistance level of hard aluminum wire, an increase of hard aluminum wire and its corresponding diameter range;
--- Added Chapter 2 Normative references;
--- Chapter 3 adds a hard aluminum resistance level and the corresponding electrical performance requirements;
--- Chapter 6 increased the duralumin aluminum hard-aluminum wire equivalent diameter and equivalent diameter deviation requirements;
--- 11.1 increased the mechanical properties of hard aluminum line;
--- Added Appendix A "Overhead Stranded with hard aluminum product line that" to facilitate the use of this standard.

Overhead stranded hard aluminum wire
1 Scope
This standard specifies the nominal diameter range of 1.25mm ~ 5.00mm hard aluminum round wire and nominal equivalent diameter range of 2.00mm ~
Mechanical and electrical properties of 6.00 mm hard aluminum wire. Hard aluminum is divided into four resistance levels, respectively, with L, L1, L2, L3 said. section
Shape is divided into two types of round lines and profiles.
This standard applies to the overhead transmission wire with hard aluminum wire.
