Deciphering the competition between national standard and non-standard, the cable industry actually hides so many tricks?

In the cable industry, there will be a variety of wires and cables, and there will also be a variety of prices. The main reason for the price difference is “national standard” and “non-standard”. Many practitioners have expressed their helplessness: it is obviously a genuine national standard product, but it is always robbed of the market by “fake national standards”. Behind this, it is actually the result of multiple rounds of competition, and each round is hidden.

The competition of copper

National standard cables use oxygen-free copper rods, which have good conductivity but high cost, while non-standard cables use a large amount of lower-priced miscellaneous copper and recycled copper. Even if the weight is the same, the cost is much lower. The national standard promotes resistance and conductivity, but users only look at the price, and the effect is limited.

The competition of auxiliary materials

Auxiliary materials such as insulation layer and sheath material can also save costs. Non-standard cables cut corners, reduce thickness, and reduce material quality. Under the seemingly “compliant” appearance, they quietly lower the cost, and the price is suddenly lower.

The competition of length

A roll of cable with a nominal length of 100 meters is actually only 95 meters or even less. Short meters are difficult to check, and it is almost unrealistic to measure one meter at a time, but it is easy to squeeze out profits in the middle.

The most hidden and terrifying

thick on both sides and thin in the middle. The beginning and the end meet the national standard, and the copper core is secretly reduced in the middle. This kind of “sandwich cable” cannot be detected in routine inspections. Unless the cable is cut open on site or the construction unit takes the initiative to report it, it isn’t easy to distinguish the true from the false.

The routine of “non-standard fake national standard” is becoming increasingly hidden, and manufacturers who truly adhere to the national standard are trapped in the quagmire of price competition. “Non-standard fake national standard” products not only damage the industry’s integrity but also expose users to huge safety hazards.

We also want to solemnly remind consumers: Cables are not just “wires”, but also carry the protection of buildings, equipment and even life safety. For your power safety and the long-term stability of construction projects, it is a responsibility to choose real national standard cables.
