我们提供线材从线轴到工作部位的各种尺寸的导线管。导线管选用的材料具备足够的抗弯折能力能在走线时存在一定数量的张力情况下，依旧维持相对固定的形状，避免线弧不合格，甚至虚焊等严重质量问题。导线管内壁有光滑涂层，保证铝线在走线时不被刮伤，同时保证导线管不易沾铝。

We provide various sizes of wire tubes from the reel to the working parts. The material selected for the wire tubes has enough anti bending ability, so that when the wiring has a certain amount of tension, it can still maintain a relatively fixed shape and avoid serious quality problems such as unqualified arc and even cold solder joints. In the inner wall of the wire tubes there is a smooth coating, to ensure that the wire tubes cannot be scratched when the aluminum wires wire, and at the same time to ensure that the wire tubes not easy to dip aluminum.
