动点胶机电线的质量如何鉴别
浏览数:5

1、首先看电线的包装,国标的点胶机电线往往做都比较好,整齐,手拿上去有质量感。国标的电线1.5到6平方的电线要求绝缘厚度是0.7mm,太厚的就是非标的了,相应的他的内芯就肯定不够,线皮你可以用力的扯一下,不容易扯破的就是一般就是国标的。然后用火烧一下,离开后5s内熄灭的,有一定阻燃功能的基本上为国标线。

First look at the packaging of wires, national standard wires tend to do better, neat, hands up with a sense of quality. National standard wire 1.5 to 6 square wires required insulation thickness is 0.7mm, too thick is not the standard, the corresponding inner core is certainly not enough, line skin you can pull the force, is not easy to tear the general is the national standard. Then use the fire to burn. After leaving the 5S, the flame retardant function is basically the national standard line.

2、其次看内芯,内芯的材质光亮度越高铜质越好,并且光度均匀,有光泽,没有层次感。国标要求内芯一定要用无氧铜。非标的很多用黑杆铜,可能存在事故隐患。同时内芯的粗细国家也有要求,但不是很严格,只是很小的一点点,一般用肉眼看不出来的误差。

Next look at the inner core. The higher the brightness of the inner core material is, the better the copper is, and the luminosity is uniform, luster and no sense of layering. The national standard requires that the inner core must be used with oxygen free copper. Many non standard copper rods with black rods may cause accidents. At the same time, the thickness of the inner core is also required by the state, but it is not very strict. It is only a tiny bit of error which is usually invisible to the naked eye.


3、最后看长度,国家没有强制一定要打米,可是有很多点胶机厂家也打了米,打了米的并不一定是国标的,有的国标也没有打米,非标的打米那只是一种营销手段。国家规定电线上一定要打有一定的标识,上面一般有产品的商标,厂家名称,执行标准等。

The last look at the length, the state does not have to make sure to play rice, but there are many manufacturers also hit the rice, the rice is not necessarily the national standard, some national standard has not hit rice, the non - standard hit rice is just a marketing means. The state stipulates that certain marks must be marked on the wires, which generally include trademarks, factory names, and implementation standards.
