Analysis of the real difference between the national standard cable and non-standard cable

Cable practitioners over the years are familiar with a sensitive topic: selling GB is too difficult, said their cables are GB, non-standard also said that their own is GB, the result is that the advantages of the offer, which once let the cable market practitioners really helpless; what GB cable and non-standard cable where the real difference, you can do a detailed understanding of the following points: 1. Through the weight of the copper counting costs. The beginning of the effect, but do the national standard ignored a problem, your copper is oxygen-free rod, non-standard is not, when the weight of copper scrap and oxygen-free rod is the same, the price of copper scrap and oxygen-free rod but the difference of 10%. So the national standard cable spends a lot of effort to publicize the failure of the national standard and non-standard guaranteed difference of 10%. 2. jerry-built on the auxiliary materials. The state has increased resistance checks, while the conventional products have also increased inspection efforts, non-standard cables and began to work on accessories, if the copper accounted for 70% of the cost of the cable, then the cost of auxiliary materials accounted for 20% or so, that is, 20% of the cost, if the material is a little bit inferior, and the national standard can be a difference of 5% of the price. As you can see, many of the recent exposure of the cable, are auxiliary materials on the problem.3. Wire short meter to cable short meter. In fact, short meters of this thing has always existed, this is the most difficult to check. Used to be BV on the frequent presence of, for example, 95-meter line, 98-meter line, or 90 meters, and now because of the increased number of inspection projects, the inspection of the product has been fully included, so non-standard and began to work in this direction. I hope you pay attention, 100 meters to reduce 1 meter, 1% of the profit out. 4. Both sides of the thick middle thin. That is to say, both ends of the cable are national standard, the middle part is non-standard, so save a lot of cost, the corresponding price of the cable will be much lower. You can't test the cable to intercept it from the middle, so that's how the leak was drilled. At present, the most worried about is the fourth, as long as the use of units and cable manufacturers together to conceal, simply can not check. Should we dig the cable out of the ground and measure it? This is also why the same said "national standard", but the price difference is so big reason.
