标题: III类灯串的导线的规格型号和线径要求？ [打印本页] 作者: flym3201 时间: 2009-5-27 11:29 标题: III类灯串的导线的规格型号和线径要求？ III类灯串的导线的规格型号要求，感觉标准说的不够清楚，例如一个户外用，有串联也有并联的III类灯串应该用什么规格的导线？是H03VVH2-F，还是H03RN-F，或者H05RN-F？ # z' l+ W! I- A7 g" C5 a0 g( D# J" C, {! ]+ G- ]
另外关于导线的线径，可以小于0.4mm2,但不能小于0.2mm2,是这样吗？ 4 s) {5 j8 ]! }& k8 t3 }) Q请熟悉这类产品标准的朋友指教，谢谢！作者: zengquwen123 时间: 2009-5-27 16:14
我司做的灯串，低压的不能小以0.2MM2,但如整套灯串功率大于40W，则电线为0.4MM2~0.5MM2.作者: flym3201 时间: 2009-6-1 21:36
今天终于找到答案了，功率小于50W的III类灯串的导线绝缘只要满足5.3.1 of 60598-1的要求就可以了，下面的内容供大家参考： # P6 _8 }0 {8 ?+ X) v20.10.1 Subclause 5.2.2 of section 5 of IEC 60598-1 does not apply.
