Analysis of the true difference between GB cable and non-standard cable
A sensitive topic that cable operators are familiar with these years: it is too difficult to sell the national standard.
A sensitive topic that cable operators are familiar with these years: it is too difficult to sell the national standard. They all say that their cable is the national standard. The non-standard one also says that it is the national standard. The result is the advantage in the quotation. Market practitioners are really helpless;
What is the real difference between the national standard cable and the non-standard cable? You can learn more about the following points:
1. Calculate the cost by the weight of copper. It has an effect at the beginning, but the national standard ignores a problem. Your copper is an anaerobic rod, but the non-standard is not. When the weight of scrap copper and anaerobic rod is the same, the price of scrap copper and anaerobic rod is different. %. Therefore, the national standard cable spent a lot of publicity, and ultimately failed, the national standard and the non-standard guarantee bottom difference of 10%.
2. Cut corners on the auxiliary materials. The state has increased the resistance inspection, and at the same time increased the inspection of conventional products. 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 is about 20%. 20% of the cost, if the material is used a little bit, and the national standard can be 5% difference. Everyone has also seen that many of the cables that have been exposed recently have problems with the accessories.
3. Wire short meters to short cable. In fact, the short-term thing has always existed, this is the most difficult to check. It used to be a BV. For example, 95 meters, 98 meters, or 90 meters. Now because of the increase in inspection items, the products that have been inspected are all included, so the non-standards have begun to work in this direction. I hope everyone will pay attention, 100 meters down 1 meter, 1% of the profits came out.
4. Both sides are thick and thin. That is to say, the cables at both ends are national standard, and the middle part is non-standard, so a lot of cost is saved, and the price of the corresponding cable will be much lower. You can't detect the cable from the middle, so the leak is so drilled.
At present, the most worrying thing is the fourth one. As long as the use unit and the cable manufacturer are concealed together, there is no way to check. Is it necessary to dig the cable out of the ground for measurement? This is why it is also said to be "national standard", but the price is so different.
