Analysis of the real difference between national standard cables and non-standard cables,江苏兴缘高温线缆有限公司

A sensitive topic that cable practitioners have been familiar with in recent years is that it is too difficult to sell cables that meet national standards. People say their cables are national standards, and even non-standard ones claim they are national standards. As a result, they have an advantage in quoting prices, which has left cable market practitioners feeling helpless;

The real difference between national standard cables and non-standard cables can be understood in detail from the following points:

Calculate the cost based on the weight of copper. At the beginning, there was an effect, but those who followed the national standard overlooked one issue: your copper is an oxygen free rod, while non-standard ones are not. When the weight of scrap copper and oxygen free rods is the same, the price difference between scrap copper and oxygen free rods is 10%. So the great effort put into promoting the national standard cable failed, with a 10% difference in the minimum guarantee between the national standard and non-standard.

2. Cutting corners on auxiliary materials. The country has increased resistance inspections and also intensified inspections on conventional products. Non standard cables have started to focus on auxiliary materials. If copper accounts for 70% of the cost of cables, then auxiliary material costs account for about 20%, which is the cost of these 20%. If the materials used are slightly inferior, the price can differ by 5% from the national standard. As you can see, many cables that have been exposed recently have problems with auxiliary materials.

3. Short distance from wire to cable. In fact, the issue of short rice has always existed, and it is difficult to investigate. Previously, it was commonly found on BV, such as 95 meter, 98 meter, or 90 meter products. Now, due to the increase in inspection items, all inspected products have been included, so non-standard products have started to focus on this direction again. I hope everyone can pay attention that reducing 1 meter from 100 meters results in a 1% profit.

4. Thick on both sides and thin in the middle. That is to say, both ends of the cable are in accordance with the national standard, and the middle part is non-standard, thus saving a lot of costs, and the corresponding cable price will be much lower. You can't cut the cable from the middle, right? That's how the leak got drilled.

At present, the concern is the fourth one, as long as the user unit and cable production enterprise conceal it together, it is impossible to investigate. Do we need to dig the cable out of the ground for measurement? This is also the reason why the price difference is so large despite being labeled as "national standard".
