标准摘要
[中文适用范围]: 本国际标准规定了同心绞合架空导线的电气和机械特性,该导线在绞合之前、期间或之后形成或成型,由以下任何金属线的组合制成: a) 硬铝,符合 IEC 60889 指定为 A1; b) 绞合前按照 IEC 60889 指定 A1F 线成型的硬铝; c) 按照 IEC 60104 指定为 A2 或 A3 的硬铝合金; d) 按照 IEC 60104 标准指定为 A2F 或 A3F 绞合前成型的硬铝合金; e) 普通强度钢,指定为 S1A 或 S1B,其中 A 和 B 是镀锌层等级,分别对应于 1 级和 2 级; f) 高强度钢,指定为S2A或S2B; g) 超高强度钢,指定为S3A; h) 铝包钢,指定为 SA。以下是一些可能的导体名称的示例。其他组合也是允许的。 • A1F、A2F、A3F • A1F/S1A、A1F/S1B、A1F/S2A、A1F/S2B、A1F/S3A • A1F/A1、A1F/A2、A1F/A3 • A1F/SA、A2F/SA、A3F/SA上面未包括的其他可能的导体类型并未被明确排除。 [外文原描述]: Specifies the electrical and mechanical characteristics of concentric lay, overhead conductors of wires formed or shaped before, during or after stranding, made of combinations of any of the following metal wires: a) hard aluminium as per IEC 60889 designated A1; b) hard aluminium as per IEC 60889 designated A1F wire shaped before stranding; c) hard aluminium alloy as per IEC 60104 designated A2 or A3; d) hard aluminium alloy as per IEC 60104 designated A2F or A3F shaped before stranding; e) regular strength steel, designated S1A or S1B, where A and B are zinc coating classes, corresponding respectively to classes 1 and 2; f) high strength steel, designated S2A or S2B; g) extra high strength steel, designated S3A; h) aluminium clad steel, designated SA.
