4.1.1.7 Stranding 绞线 4.1.1.7.1 General 概述 Flexible conductors shall be bunch-stranded or rope-lay-stranded and shall be composed of wires as shown in Table 2, except that conductors 13.3 mm2 (6 AWG) and larger shall be rope-lay-stranded. 软线导体应使用于束绞或者绳绞并且符合表格2的内容，除了导体6AWG和更大的都应该绳绞。 4.1.1.7.2 Lay of strands 绞距 4.1.1.7.2.1 The length of lay of rope-stranded and bunch-stranded conductors shall be not greater than the values shown in Table 3, when tested in accordance with the test, Length of Lay (uncovered components), in CAN/CSA-C22.2 No. 2556, UL 2556, or NMX-J-516-ANCE. The direction of lay is not specified. 束绞和绳绞导体节距的长度不得大于表3所示的CAN/CSA-C22.2 No. 2556, UL 2556, or NMX-J-516-ANCE标准。节距方向没有指定。 4.1.1.7.2.2 The maximum acceptable length of lay of strands of a 22 AWG conductor used in Type CXTW or XTW shall meet the requirements in Table 3 or shall be based on the performance of the finished type in the abrasion and flexing test described in Clauses 5.1.20 and 5.1.21 respectively 型号为CXTW或者XTW使用22AWG导体节距的最大可接受长度应符合表格3中的要求或者应根据分别于第5.1.20和5.1.21中所述的成品类型的磨损和弯曲试验中的描述。 4.1.1.7.2.3 The length of lay of the individual strands comprising each bunch-stranded member in a rope-lay conductor shall be not more than 30 times the overall diameter of the member. The direction of lay of the individual strands comprising each bunch-stranded member is not specified. 包含在一个绳绞导体中每个束绞成员的单独节距的长度不能超过30倍的总的导体外径，未指定每个束绞成员的单个绞距的方向。 4.1.1.7.2.4 For 8.37 mm2 (8 AWG) and larger conductors with rope-lay-stranded conductors, the conductor shall be laid up as follows: 对于8AWG和更大的绳绞的导体应按照如下要求： (a) The length of lay of the outer layer of a rope-lay-stranded conductor shall be as specified in Table 3. The length of lay of other layers is not specified. （a）绳捻绞合导体的外层节距的长度应按照表格3的要求。绞合的其它层的节距长度未指定。 (b) The length of lay of the individual strands comprising each concentric-lay -stranded member in a rope-lay conductor shall be neither less than 8 nor more than 16 times the outside diameter of the member.
