在对电线的使用过程中,电线电缆的使用寿命以及电线电缆的绝缘性都会受到其自身扭曲的影响。电线电缆的弯曲性能,指的是电线电缆能够承受多少次的弯曲,通过在弯曲设备上的反复弯曲,直到电线这段,能够检测出电线电缆的弯曲性能,而其主要的检测项目包含扭曲性能检测、卷绕性能检测等。
 
In the process of using wires, the life of wires and cables and the insulation of wires and cables will be affected by their own distortion. The flexural performance of wire and cable refers to how many times the wire and cable can bear the bending. Through repeated bending on the bending equipment until the wire section, the flexural performance of the wire and cable can be detected, and the main testing items include distortion performance detection, winding energy detection and so on.
 
1 卷绕性能检测。对于电线电缆产品来讲,能够拥有好的卷绕性能是十分重要的,因此卷绕性能也是评定电线电缆产品质量高低的重要标准之一,电线电缆产品当中的金属线应能够随意卷绕,柔韧性良好。要对电线电缆的卷绕性能进行检测,最主要的方法就是按照规定将电线电缆进行卷绕,并观察电线的变化。

1 winding performance testing. For wire and cable products, it is very important to have good winding performance, so the winding performance is one of the important criteria for evaluating the quality of wire and cable products. The wire and cable products in wire and cable should be able to roll around freely and have good flexibility. To detect the winding performance of wires and cables, the most important method is to wire and wire the cables according to regulations and observe the changes of wires.
 
2 扭曲性能检测。要对电线电缆的扭曲性能进行检测,主要是检测电线电缆产品在扭曲的作用之下,是不是会出现塑性变形的情况,而要判断在电线电缆产品当中,其金属线材是否有拥有一定的缺陷,或者是金属线材的分布是否均匀,扭曲行能的检测都达到目的,而性能检测则需要根据电线电缆产品能够承受多少次的扭曲来进行区分。
 
2 distortion performance detection. To test the distortion of wire and cable, it is mainly to test whether the wire and cable products will be plastic deion under the effect of distortion, but it is necessary to judge whether the metal wire has certain defects in the wire and cable products, or whether the distribution of metal wire is uniform, and the twisted line can be twisted. The detection is achieved, and performance testing needs to be differentiated according to how many times the wire and cable products can withstand the distortion.
