How to detect the quality of wire and cable
How to detect the quality of wire and cable is essential in the power system, especially on the transmission line. It has a good classification, special cable, absolute green cable, etc. the wire and cable are used to transmit electric (magnetic) energy, information and the wire products that can be converted by electromagnetic energy, and the broad electric wire is also called cable, and the narrow sense of electric power is used in the broad sense.
It refers to the coloured edge cable, which can be defined as a aggregation of the following parts; one or multiple green wire cores, and the covering layers that they may have, the total protection layer and the outer protective layer, and the cables with additional and no great conductors.
Check the shielding layer network: whether the number is enough? Copper wire mesh, check the weldability, tin copper wire system to see it is not copper wire, the hardness of the aluminum magnesium alloy wire is obviously larger than the copper wire mesh sparsity, the distribution is uneven, and the insulation layer is not tight and so on is poor cable; with the fire machine core wire, if it is copper aluminum, it is easy to see the internal pigments. Color is not the same as the outside copper; peeling off the outer skin, looking at the knitting angle of the shielding layer, if basically all stand up, then basically you can see that the knitting angle is bigger, for the work of cutting the material.
It can be seen that at the very beginning, we should be careful when choosing cables, and we must not buy cheap products without cost. We should purchase some cables produced by large enterprises, not only with quality assurance, but also a lot better service. The SITONGCABLE" is the known brand of Electrical and Cable Technology Co., Ltd., which is a large wire and cable enterprise integrated with R & D, manufacturing and sales.SITONG cable products sell well all over the country, quality assurance, service supremacy, won the high praise of the vast number of consumers.
