Quality is the life of the enterprise, this is the experience of many enterprises; after all, because quality is not only related to the rise and fall of the company, so not good companies may be rejected by consumers, and be eliminated by the market; It is also in our immediate interest, especially for ACSR cable manufacturers, who must provide not only cable products to consumers, but also high-quality cable products to consumers; otherwise, there will be safety issues, from short circuit damage to life safety of electrical personnel. In the last article, we mentioned how cable manufacturers should ensure the quality of cable products, that is:
(1) cable manufacturers should cultivate three kinds of self-inspection awareness, mutual inspection awareness and group awareness; that is to say, employees who want to manufacture cables must self-check their products; they must provide timely feedback on quality problems found in the process or workshop and must never manufacture defective products;
(2) Before Aerial Bundled Cable (ABC) SANS 1418 Standard products are shipped out of the factory, not only in the production process, but also in the key process of quality inspection, we must strictly follow the process control; after all, the inspection of wire and cable is an important part of cable production, the more strict the quality inspection of cable, the more advanced, the higher the quality and credibility of the wires and cables the company produces. Now that we have discussed the key process of quality inspection by cable manufacturers, let us talk about what is included in the quality inspection of cables before they leave the factory? What do you need to pay attention to?
1. Measurement of the direct current resistance of a wire or cable the conducting core of the wire or cable transmits electrical energy or signals. The resistance of the wire or cable is the main index of its electrical performance, the adjacent effectors are larger than the DC voltage, but when the voltage frequency is 50Hz, the difference is very small; therefore, the cable must pass this test before leaving the factory, in addition, through this inspection, some defects in the production process can be found, for example, the cross-section of the welding wire is not up to standard, the length of the product is not correct.
2. Insulation Resistance testing insulation resistance is an important index to reflect the insulation characteristics of wire and cable products, and is closely related to the electrical strength, dielectric loss of the products and the deterioration of insulation materials under working conditions, this test is necessary to make consumers better and to use electricity more safely.
3. In order to check the quality of the wire and cable products and ensure the safe operation of the products, the insulation strength test must be carried out. Well, due to the length, I can only talk about the quality inspection of these cables before they leave the factory today. I hope you can understand
