Wire and cable industry's "dirty"

Wire and cable industry occupies 1/4 of the output value of China's electrical industry, and its product variety satisfaction rate and domestic market share exceed 90%. Wire and cable products have a wide range of applications and they cover a wide range of applications, including electricity, construction, communications, and manufacturing. Considering its quality from a large point of view is closely related to all aspects of China's national economy. From the perspective of the enterprise itself, it is also directly related to the issue of production safety. The consumer's interest is closely related to the use of consumers. However, in recent years, fire accidents caused by unqualified wires and cables have occurred frequently in our country.

Here, we explore the reasons why there are serious product quality wire and cable products in the market.

Wire and cable companies malicious price bidding

It is understood that at present, there are more than 7,000 cable manufacturers in China. As a result, the competition among cable companies has become increasingly fierce. Many companies choose to do tricks in the bidding process in order to seek more benefits. Driven by interests, nearly 40% of cable companies have begun to engage in malicious competition and other bad competition.

Some companies will find ways to cut corners after low bids, leading to serious quality problems in the successful bid projects, or because the profit margin is very small, which greatly reduces the cost of production management, resulting in successful production problems for successful projects.

Wire and cable companies cut corners

Recently, the prices of copper and various raw materials have risen sharply, and the prices of bidding for wires and cables have been relatively low. If enterprises perform production in accordance with the bidding standards and national standards, they will definitely lose money. In order to make themselves a little profitable, these companies chose to cut corners and shoddy work in the production of cables.

The manufacturing process of the cable is actually not complicated. The basic component of a cable, no matter what its purpose, is usually the conductor and the insulating sheath. The conductor is usually copper/aluminum, and the insulating housing is generally plastic. Some cable manufacturers began to ignore the inspection of raw materials into the factory in order to obtain greater profit margins. Some companies even intentionally used inferior materials. According to industry sources, many manufacturers use scrap copper to replace good copper, the difference between good copper and scrap copper is 6,000 yuan/ton, good copper is directly extracted from the ore, and the resistance value is low; the scrap copper contains impurities, and the resistance is large and natural to use. Will affect the performance of wire and cable and life. For plastic materials, manufacturers are also trying their best to cut corners. Some companies buy waste needles and other medical waste or used plastics at low prices. There are no problems with qualified products for 20 to 30 years, and inferior plastics will begin to age in two to three years. Fall off. This type of low-quality products inflow into the market is certainly unable to withstand the test of time. Long-term production operations like this will certainly have serious safety problems.

Some industry inspection agencies open the door to convenience

For people in the industry, we should all know that there must be a variety of testing institutions in the wire and cable industry. It stands to reason that these testing organizations will generally conduct strict inspections of wire and cable products in accordance with national standards. For those cables that do not meet the requirements of the key indicators such as conductor resistance and degree of cross-linking, as well as products with non-compliance of the wire diameter and the presence of materials used for cutting corners, if the testing organization finds that the quality of the product is unqualified, it will increase product inspection. The number of, and it is necessary to re-inspect the non-conforming product. How do these unqualified products pass the inspection and flow into the market?

According to an interview with the reporter, the inspection staff of some testing agencies did not strictly follow the national standard or the line inspection product in the case of the national standard testing standard. As long as some cable companies are willing to pay a certain amount of money, secretly plugged in red envelopes and privately hosted several dinners, fully expressed their own minds. The staff of some testing agencies have opened a "convenience portal" for these products that are not qualified. After knowing these "hidden rules" in the industry, people in the industry will not hesitate to use various means to obtain "passes" - reports on product testing compliance.
