- Scope
- This standard specifies the electrical and mechanical properties of shaped concentrically stranded overhead conductors. Concentric stranded overhead conductors of molded wires are composed of any of the following metal single wires formed before twisting, during twisting or after twisting: a) LY9 hard aluminum wire, in line with GB/T 17048; b) LY9X hard aluminum wire formed before twisting, Comply with the equivalent hard aluminum wire diameter in GB/T 17048; c) LHA2 or LHA1 hard aluminum alloy wire, comply with JB/T 8134; Aluminum alloy wire diameter; e) G1A or G1B ordinary-strength steel wire, A and B represent galvanized layer grades, corresponding to grade 1 and grade 2 respectively; f) G2A or G2B high-strength steel wire; g) G3A extra-high-strength steel wire ; h) LB aluminum clad steel wire. The following are examples of some possible wire type designations, other combinations are also permissible. —JLX, JLHA2X, JLHA1X —JLX/G1A, JLX/G1B, JLX/G2A, JLX/G2B, JLX/G3A —JLX/L, JLX/LHA1, JLX/LHA2 —JLX/LB, JLHA2X/LB, JLHA1X/LB Wire types not included above are not excluded.
