Industry professionals often complain: It's incredibly difficult to sell products that meet national standards. You claim to have national standard products, but others also claim their non-standard products are national standards, and their prices are 10% cheaper than yours. It's quite frustrating.

Here, Qingdao Haodong Cable takes a look back and summarizes the four-round showdown between national standards and non-standard products.

One, calculate the cost based on the weight of copper. Initially, this method was effective. However, when producing products according to the national standards, a problem was overlooked. Your copper is oxygen-free rod, while the non-standard one is not. When the weight of scrap copper and oxygen-free rod is the same, the price difference between them can reach 10%.

So the national standard cable company invested heavily in promotion, only to fail. The difference between the national standard and non-standard cables is a mere 10%.

In terms of auxiliary materials, corners are being cut. The government has intensified resistance inspections and also increased scrutiny on standard products. Non-standard cables are once again focusing on cost-saving measures in auxiliary materials. If copper constitutes 70% of the cable's cost, auxiliary materials account for about 20%. This 20% is where the difference of 5% in price with the national standard can be found. As everyone has seen, many recently exposed cable issues stem from problems with the auxiliary materials.

Three, from short lengths of wire to short lengths of cable. In fact, the issue of short lengths has always been present, and it is quite difficult to detect. It used to be common on BV, such as 95-meter wire, 98-meter wire, or 90-meter wire. Now, with the increase in inspection items, all products are included in the inspection, so non-standard products are once again focusing on this aspect. Everyone is advised to be vigilant, as reducing 1 meter to 100 meters results in a 1% profit.

Four, thick at both ends and thin in the middle. This means that the cables at both ends meet national standards, while the middle section does not, thus saving a significant amount of costs, which in turn lowers the price of the cables. After all, you can't test the cables by cutting them in the middle, which is how the loophole was exploited.

Currently, the fourth concern is particularly worrying as it involves both the user unit and cable manufacturers concealing the issue, making it impossible to investigate. Is it necessary to dig up the cables from the ground to measure them? This also explains why, despite being referred to as "national standards," the prices can vary so greatly.
