与现有技术相比，本发明的有益技术效果：
本发明的带有彩色识别带的封装管缆，包括铠装护管、封装保护层和彩色识别带，封装保护层通过非金属材料构成，将铠装护管完全包裹起来，起到保护铠装护管的作用，使得线缆整体更加耐油、耐腐、耐温，延长其使用寿命；此外，封装保护层的形状根据实际需要设计为异形单层结构、双层结构或弧形结构，且异形单层结构的凹陷部位与彩色识别带的位置相对应，减少最薄点的厚度，方便彩色识别带进行撕裂封装的工作，提高了作业效率；不同位置的中空通道内放置有线缆、光纤或油液管，根据功能的不同进行彩色识别带相对应颜色的标记，并将该标记标签贴在封装保护层上，便于工人查看，使用更加方便快捷。彩色识别带设计为多股单绳绞合而成或者多根单绳松散的搭接而成，经过加工可以染色变成各种颜色，强度高，可区分，既能分辨每根中空通道还 能撕裂封装，把线缆或光纤从封装中剥离出来。单绳的截面积更小，撕裂时更加锋利，撕裂作业更加方便快捷。
总的来说，本发明构思巧妙，布局紧凑合理，具有输送油液和数据传输的双重功能，封装保护层提高了封装管缆的耐腐蚀性，彩色识别带布置在封装保护层的最薄点位置，方便撕裂封装；每一条彩色识别带上都拥有各自的颜色标识，便于在使用时分辨出每一根中空通道内的物品。
