Over the years, cable practitioners are very familiar with a sensitive topic: it's too difficult to sell the national standard. They all say that their cables are national standard, and non-standard also say that they are national standard. As a result, they have an advantage in quotation, which once made cable market practitioners really helpless;
What's the real difference between national standard cable and non-standard cable? We can make a detailed understanding from the following points:
1. Calculate the cost by the weight of copper. At the beginning, it worked, but the national standard ignored a problem. Your copper is an oxygen free rod, but the non-standard one is not. When the weight of waste copper and oxygen free rod is the same, the price difference between waste copper and oxygen free rod is 10%. Therefore, the publicity of GB cable failed. The difference between GB and non-standard is 10%.
2. Cutting corners on accessories. The state has increased the inspection of resistance and conventional products, and non-standard cables have begun to work hard on accessories. If copper accounts for 70% of the cost of cables, then the cost of accessories accounts for about 20%, which is the 20% cost. If the materials are used a little less, the price will be 5% different from the national standard. As you can see, a lot of cables exposed recently have problems with accessories.
3. Wire short meter to cable short meter. In fact, short rice has always existed, which is the most difficult to check. In the past, BV often existed, such as 95m, 98m, or 90m. Now because of the increase of inspection items, all the inspected products have been included, so the non-standard ones began to work hard in this direction again. I hope you will pay attention to the fact that if 100 meters are reduced by 1 meter, 1% of the profit will come out.
4. Thick on both sides and thin in the middle. 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 price of the corresponding cable will be much lower. You can't cut the cable from the middle, so that's how the leak was drilled.
At present, the fourth one is the most worrying. As long as the user and the cable manufacturer conceal it together, there is no way to check. Is it necessary to dig the cable out of the ground for measurement? This is also the reason why it is also called "national standard", but the price difference is so big.
