It shows that the processing technology is superb, and this kind of service entrance wire has a superior quality. On the contrary, it shows that the service entrance cable is inferior if the surface is smooth, you can not see the regular “roughness” in the composed net from the appearance, and cable is loose through pinch it.
Check the copper conductor of the service entrance cable
Check the copper conductor of the service entrance cable. The conductor of service entrance wire has copper conductor and aluminum conductor. Now only say copper conductor. For high-class copper conductor, the diameter meets the requirements. It is good in material and has certain softness. Scratching the surface or through the section of copper conductor, you can see the natural colour. There is no rust on the surface of copper conductor. But for inferior copper conductor, the diameter is less than the standard. The conductor is so tough that it is difficult to cut it, which means the conductor contains a lot of impurity.
Check the cohesive force of the service entrance cable
Check the cohesive force between core wire and insulation layer of the service entrance cable. You can cut open insulation layer and draw back core wire according to the peel direction, and see if the core wire and insulation layer have great cohesive force. The cohesive force of high-class service entrance cable is strong, but the inferior one dose not.
Do longitudinal tensile test of the service entrance cable
Longitudinal tensile test of the service entrance cable. Take a meter of service entrance wire, then peel off the core wire, insulation layer, and outer sheath. The method is: the hands respectively hold adjacent two layers of the cable and pull in the opposite direction. The high-class service entrance cable is not allowed to stand still, and the poor cable can be easily pulled out.
Measure length or check weight and the locality of the service entrance cable
You can judge quality of service entrance cable by measure the length and check the weight. Usually, forged and fake service entrance wire has not locality. However, it also has some ambiguous origins, such as made in China, made in certain city, and so on. As a matter of fact, this means no locality.
