Guangdong Industrial and Commercial Inspection Wire and Cable 60% failed!

On February 6, the Guangdong Provincial Administration for Industry and Commerce released a report on the monitoring of wire and cable quality in circulation. The results showed that of the 100 types of wire and cable products extracted, 63 products were generally unqualified and their qualification rate was less than 40%.

At the same time, the Guangdong Provincial Administration for Industry and Commerce selected the same type of goods produced by several companies that monitored unqualified wire and cable products last year for follow-up monitoring, and again found that the nominal manufacturers were Tianhong Wire and Cable Factory, Shenzhen Kanglixin Cable Co., Ltd., and Foshan City. The Shunde Leliu Town Lexi Xunheng Electric Wire Factory, Guangzhou Shuntong Electric Wire Cable Co., Ltd., and Guangzhou Weiqian Wire and Cable Co., Ltd., and other five types of wire and cable products produced by other units failed.

Tianhong Cable may have a company's impersonation production. I learned that in this monitoring, Aotong brand PVC insulated wire (BV2.5mm2) produced by Guangzhou Tianhong Wire and Cable Factory and a copper core PVC insulated wire produced by Tianhong Wire and Cable Factory. Three products such as wire (BV2.5mm2) and aluminum-core PVC insulated wire (BLV2.5mm2) were found to be unqualified, and the latter two were even detected as unqualified conductor resistance, length, etc. Another product of the same type produced by a product manufacturer was also detected as unqualified in 2010.

The author then called Guangdong Tianhong Cable Co., Ltd., and the company’s technical staff said that it has not received the relevant notice from the Provincial Bureau of Industry and Commerce, and thus failed to understand the details of the monitoring. “Last year we also received notification from the Provincial Bureau of Quality Supervision about the failure of our products. However, it was later proven that the printed products, trademarks, etc. of unqualified products had many inconsistencies with the products we produced, and were not products manufactured by Tianhong. The company produced Tianhong's products by name.” The company’s quality department also said that the company has never produced a product with the model “BLV”. It is impossible for up to four or five items to be unqualified, and the company’s nominal name As the "Guangzhou Tianhong Wire and Cable Factory," there is no label "Australian pass", and the production company whose brand name does not conform to the nominal name is most likely to be an unfamiliar production of other manufacturers. It is said that Tianhong will continue to follow this matter and carry out related processing.

The fierce competition in the cable association led to shoddy cases. For the low qualified rate of this monitoring, the staff of the quality inspection office of the Maoming Quality Supervision and Inspection Institute in Guangdong Province, who was entrusted with the monitoring, told the reporter that the price issue had either passed or failed. The main reason for the low rate. "Companies do not produce according to national standards, especially for small businesses, and use inferior materials to substandard, which can easily lead to unqualified monitoring." He said that the wire and cable industry has a simple manufacturing process, low industry entry barriers and intense competition. The price of products is too high to have a market. To save production costs, many companies, especially small ones, can only work on raw materials.

“At present, there are more than 7,000 small and medium wire and cable companies in China, but most of them are low-end products, and the price of products has become a magic weapon for many small and medium-sized enterprises. Since wires and cables are typical materials, light industry, raw materials The price of the material accounts for 70% to 80% of the total cost, so the quality of raw materials will affect the quality of wire and cable products to a large extent.” The staff of the technical department of the China Wire and Cable Association stated that the reason why small enterprises can provide ultra-low-cost products The product is nothing more than making a fuss about the raw materials. The quality of the product can be imagined. "On the other hand, there are companies that have fake products that produce some products that are sold well in the market, leading to unqualified companies in monitoring."

Some of the wires used unqualified copper materials are prone to overheating. In order to save costs, some manufacturers use copper materials that do not meet the standards, which leads to overheating of the wires during use. This leads to burning. In addition, spot checks have found that wires sold on the market are generally not long enough. problem. Failed list can be found on the website of the Provincial Administration for Industry and Commerce. Of the 100 commodities monitored this time, 63 of the commodities examined were generally unqualified, and 37 samples were found to have failed.

Unqualified items include: 20°C conductor resistance, insulation resistance, structure and dimensions, insulation and sheath before and after aging (after) tensile strength and elongation, sample length, signs, etc. The reporter found that the most problematic items in unqualified projects were 20°C conductor resistance, length and tensile strength before and after insulation aging.
