Many cable industry professionals complain: It's so hard to sell products that meet national standards. You claim to have national standard products, but others selling non-standard products also claim theirs are national standards, and their prices are 10% cheaper than yours. It's really frustrating.

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

One, cost calculation based on the weight of copper. Initially, this method was effective. However, when adhering to national standards, one issue was overlooked: your copper is oxygen-free rod, whereas the non-standard version 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 put a lot of effort into promotion, but it failed, with a 10% difference between national standard and non-standard cables.

Two, cutting corners on auxiliary materials. The country has intensified resistance inspections and also increased checks on regular products. Non-standard cables are once again focusing on auxiliary materials. If copper accounts for 70% of the cable's cost, then the auxiliary material cost takes up about 20%. It's this 20% of the cost where using slightly lower-quality materials can result in a 5% price difference from the national standard. As you have seen, many recently exposed cables have issues with their 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 very difficult to detect. It used to be common on BV, such as 95-meter wire, 98-meter wire, or 90-meter wire. Now, due to the increase in inspection items, all products are included in the inspection, so non-standard products are once again working on this aspect. We hope everyone will pay attention: reducing 1 meter to 100 meters results in a 1% profit.

Four, thick at both ends and thin in the middle. That is to say, the cables at both ends meet national standards, while the middle section does not, thus saving a significant amount of costs, and accordingly, the price of the cables is much lower. You can't possibly test the cables by cutting from the middle, which is how the漏洞 was exploited.

Currently, the fourth concern is particularly worrying, as it involves both the user unit and cable manufacturers in concealment, making it nearly impossible to investigate. Is it necessary to dig up the cables from underground for measurement? This also explains why, despite being labeled as "national standards," there is such a significant price discrepancy.
