Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard uses the translation method identical with IEC 62420.2008 "containing one or more gaps concentric lay stranded conductors."
Correspondence between the consistency of the standards of international documents and normative references of the following documents.

Containing one or more gaps concentric lay stranded conductors
1 Scope
This standard specifies containing one or more aluminum or aluminum alloy wires of self-supporting layer of concentric lay stranded conductors (see Figure 1) electrical and
Mechanical behavior. The wire of any combination of the following single line of metal from.
a) comply with GB/T 17048-2009 hard aluminum, named LY9, abbreviated as L;
b) in line with GB/T 23308-2009 aluminum - magnesium - silicon alloy round wire, named LHA1 or LHA2;
c) in line with GB/T 30551-2014 heat-resistant aluminum alloy wire and named NRLH1, NRLH2, NRLH3, NRLH4;
d) compliance with IEC 60888. 1987 Grade 1 strength galvanized steel wire, named G1A or G1B;
e) compliance with IEC 60888. 1987, class 2-strength galvanized steel wire, named G2A or G2B;
f) compliance with IEC 60888. 1987 Level 3 strength galvanized steel wire, named G3A;
g) compliance with IEC 61232.1993 aluminum clad steel wire, named LB20A, LB27, LB30 or LB40.
Note. This standard includes self-damping wire and wire gap-type structure Although the two conductors have the same structural characteristics between the twisted layer and layer has a twist
Or more gaps exist, but they are designed for different purposes. Self-damping conductors containing one or more gaps in order to increase self-damping, and the gap
Gap when the wire is to install aluminum layer can slide freely on the center line of the core, and therefore the number of no more than one gap.
