LASER-MARKABLE CABLES AND SYSTEMS FOR MAKING THE SAME

Laser-markable cable layers for a cable are provided. The laser-markable cable layers include an inner layer formed of a first polymer material and an outer layer formed of a second polymer material and a laser-marking compound. The outer layer is about 0.5% to about 50% of the thickness of the inner layer. The laser-markable cable layers surround a wire or cable core. Methods of marking a cable having laser-markable cable layers are also provided. 提供用于线缆的激光可标记的线缆层。所述激光可标记的线缆层包括由第聚合物材料形成的内层和由第二聚合物材料和激光标记用化合物形成的外层。所述外层为所述内层的厚度的约0.5％-约50％。所述激光可标记的线缆层包围电线或线缆芯。还提供对具有激光可标记的线缆层的线缆进行标记的方法。
