GB/T 20141-2006 in English

《GB/T 20141-2006型线同心绞架空导线》由TC422（全国裸电线标准化技术委员会）归口，主管部门为中国电器工业协会。
本标准规定了型线同心绞架空导线的电气和机械性能。型线同心绞架空导线由LY9铝线、LY9X绞前成型的硬铝线、LHA2或LHA1硬铝合金线、LHA2X或LHA1X绞前成型的硬铝合金线、G1A或G1B普通强度钢线、G2A或G2B高强度钢线、G3A特高强度钢线、LB铝包钢线组合而成。

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.
