请按HD308规定颜色 生产VDE电缆,任何颜色的改变或是排列的改变都是不符合标准的。if a manufacturer wants to use a VDE-mark all requirements of the relevant specification must be fulfilled. That means that also the colours must be according to the standard HD 308. If we find samples on the market with other colours and VDE-mark we have the right to cancel the licence immetiately and to publish it on our website. Klaus Prohaska
“那四芯线用棕、蓝、黑、黄绿是不是也是不符合标准啊?”
----in the case you have 3 phase installation (delta-connected) you need the core colours: Y/G, brown, black and grey, but for example for a 2 phase installation, which is seldom in Germany, they use the core colours Y/G, blue and brown and black.
----HD308的Table 1 不也是有4a的选项吗?
----请注意是 Y/G, blue and brown and black,描述颜色的顺序也是不能错的
