Analysis of the Real Difference between National Standard Cable and Non-standard Cable
Release time:
2020-01-05
Over the years, cable practitioners are very familiar with a sensitive topic: it is too difficult to sell the national standard. they all say that their cables are national standard, and non-standard ones also say that their cables are national standard. as a result, they have the advantage in quoting. this once made the practitioners in the cable market really helpless.
Over the years, cable practitioners are very familiar with a sensitive topic: it is too difficult to sell national standards, they all say that their cables are national standards, and non-standard ones also say that their cables are national standards. As a result, they have an advantage in quoting prices, which once made cable market practitioners really helpless;
What is the real difference between national standard cable and non-standard cable, you can do a detailed understanding from the following points:
1. The cost is calculated by the weight of copper. At the beginning, it was effective, but the national standard ignored a problem. Your copper is an oxygen-free rod, but not a non-standard one. When the weight of scrap copper and oxygen-free rod is the same, the price difference between scrap copper and oxygen-free rod is 10%. Therefore, the national standard cable made great efforts to publicize and failed. The difference between the national standard and the non-standard guarantee was 10%.
2. cut corners on accessories. The state has stepped up the inspection of resistance and the inspection of regular products. Non-standard cables have begun to make efforts on auxiliary materials. If copper accounts for 70% of the cost of cables, then the cost of auxiliary materials accounts for about 20%, which is the 20% cost. If the materials are used slightly second, the price will be 5% different from the national standard. As you can see, many cables that have been exposed recently have problems with auxiliary materials.
3. Wire short meter to cable short meter. In fact, the matter of short rice has always existed, which is the most difficult to find out. In the past, it often existed on BV, such as 95-meter line, 98-meter line, or 90-meter line. Now, due to the increase in the number of inspection items, all the products inspected have been included, so non-standard products have begun to work hard in this direction. I hope everyone will pay attention to the fact that 100 meters will be reduced by 1 meter and 1% of the profit will come out.
4. Thick on both sides and thin in the middle. In other words, the cables at both ends are national standard, and the middle part is non-standard, so a lot of costs are saved, and the price of the corresponding cable will be much lower. You can't intercept the cable from the middle, so this is how the leak was drilled.
At present, the most worrying thing is the fourth. As long as the user and the cable manufacturer conceal it together, there is no way to check it. Is it necessary to dig out the cable from the ground to measure it? This is also why it is also said to be "national standard", but the price is so different.
