Wire and cable, as the main carrier of power transmission, are widely used in electrical equipment, lighting circuits, and household appliances. The quality of wire and cable directly affects the quality of projects and the safety of consumers' lives and property. China’s quality inspection team paid special attention to this issue.
There are five outstanding problems in the wire and cable industry. In recent years, China's sustained and rapid economic growth has provided a huge market space for the wire and cable industry. According to incomplete statistics, China currently has more than 7000 various types of wire and cable manufacturing enterprises, with an annual output value of about 700 billion yuan. Although the output value is huge, but from the perspective of the development level of the entire industry, there are still problems of low industry concentration, decentralized technology, and low product technology content.
Most types of cable products in the domestic market are in excess supply. China’s quality Wanli Bank discovered through unannounced visits that for profit and survival, a few manufacturers cut corners and materials, and poor quality wires and cables flood the market. Non-standard products are difficult to prohibit.
The main problems of poor quality non-standard wire and cable are as follows:
1, 20 °C conductor resistance exceeded.
There are two main reasons: 1) The use of inferior copper materials, the relevant state regulations are clear, the copper wire of electric wire and cable should use electrolytic copper, and some companies use recycled copper or copper clad aluminum, copper clad iron, copper clad steel to impersonate copper. Regenerated copper impurities are too high and can easily cause excessive conductor resistance. 2) The wire diameter is too small. The smaller the wire diameter is, the smaller the actual cross-sectional area of ​​the wire diameter is than the nominal cross-sectional area. This is mainly due to the lack of strict control over the process of some production enterprises or due to cutting corners. Excessive conductor resistance, excessive heating of electrical wires, in addition to consuming large amounts of energy, more importantly, it is easy to cause fires and cause major disasters.
2. The tensile strength and elongation at break of the insulation and sheath are not up to the standard.
The insulating layer of the wire and cable is mainly used to prevent leakage and ensure safety. If a recycled or highly-impurified rubber (33405, 245.00, 0.74%) or plastic (12,000, -40.00, -0.33%) is used as the insulating layer, its tensile strength and elongation at break are hard to meet the standard. required. Insulation layer is not up to the standard wire and cable, easy to install insulation cracking, so that live conductor exposed, threatening personal and property safety. Such as the Hunan Provincial Bureau of Quality and Technology Supervision announced the label Hengyang Jinfu Wire and Cable Factory, Shanghai Huayi Electric Group Co., Ltd., Changsha City Jinheng Wire and Cable Co., Ltd., Hengyang Xiangnan Wire and Cable Factory and other products, before the aging test quality problems More prominent.
3, the printing logo does not meet the requirements.
Although the printed logo does not directly affect the intrinsic quality of the goods, it will be misleading to consumers to some extent. Therefore, the national mandatory product standard stipulates that the printed logo on the line body must clearly and correctly mark the name of the factory (or trademark). However, there are still some corporate logos that are not complete, or the important information such as specifications, voltage levels, etc. are incorrectly labeled. There are also some producers of inferior or counterfeit products who, in order to evade the blow, intentionally do not use the name of the factory or indicate their own production address. Such as the Hunan Provincial Bureau of Quality Supervision announced the labeling of Hengyang Xiangnan Wire and Cable Factory, Hengyang City Hengxiang Wire and Cable Factory, Changsha Jinqiao Cable Co., Ltd. and other companies' products, the address of the manufacturer of the label, after inquiry by the post office, are “No such person was found on the original siteâ€, indicating that the address marked on the product simply did not have this production company.
4. Infringement of intellectual property rights and production of non-standard products.
The phenomenon of infringement of intellectual property rights is mainly manifested in misappropriation of product brands that use brand names and have a good reputation in the market. Produce products that do not meet the national standards and cut corners in accordance with the wishes of customers.
5, without the mandatory 3C certification, unauthorized production and sales.
Mine rubber soft cable; AC rated voltage 3kV and below railway rolling stock wire and cable; Rated voltage 450/750V and below rubber insulated wire and cable; Rated voltage of 450/750V and below PVC insulated wire and cable products are required to go through the country Mandatory certification can be produced and sold. However, in the investigation, it was found that some companies' insufficiency of 3C certification for wire and cable products, and there were cases of unlicensed, fraudulent or stolen 3C certificates.
Field investigation: The chaos in the wire and cable sales market On February 19, 2011, China Quality Wanli Mingchaarun visited the market in Yuncheng, Shanxi Province. The investigation found that a company named Yuncheng Jinqiao Welding Material Co., Ltd. sold a lot of low quality without 3C certification. BV2.5mm2 wire. The manufacturer of this line identification is "Zhengzhou Third Cable Co., Ltd.". The trademark is "Zheng Xing." Under normal circumstances, the national standard BV2.5mm2 wire market price is about 180 yuan per plate, and the product price is only 130 yuan. After field measurement, the diameter of the wire is less than 1.4mm.
On February 24th, 2011, the Chinese quality Wanli Mingzang unannounced visit group went to the Lanzhou Zhongbang wire and cable direct sales office in Yinchuan, Ningxia. On the wall of the shop were the Lanzhou Zhongbang Wire and Cable Group and the Yinchuan Sales Department of Ningxia Shuobang Wire and Cable Company. The logo and the bold red character in the upper right corner indicate the solemn promise of "100 meters and a penalty of 10". In the following, the business concept of "honest and sincere" is written in red letters.
China's quality trips to the capital and unannounced visits to staff members posing as site leaders need to purchase the standard BV2.5mm2 wire, the shop owner quoted 140 yuan per plate. In the process of talking to the boss, the boss clearly stated that these lines are "supervisors in the construction site and must be given a good job by the supervisors." They also said that they need to be "non-standard", as long as they tell them in advance what they need. " Very convenient." When the unannounced interviewer asked the shop owner if the wires had passed the censorship review, the boss said, "Yes, but if the supervisor wants to have a special card for you, it won't go through any lines, including the $180 price." "Is it human?" the boss said meaningfully.
In another shop not far from the neighbor, when the boss heard that the customer wanted to mark the line, he clearly stated that all the manufacturers are now using the national standard line, but he enthusiastically told the customer to “change the formâ€, that is, to use BV2.5mm2. Label for BV1.5mm2 label.
At the marine wire and cable distribution office, the boss also stated that non-standard marking lines should be made. The BV2.5mm2 cable is priced at 140 yuan per roll. And the unannounced visits group claimed that: This line is a bit thin, but in Wuzhong City, he certainly can give "check the past." Shenyang Yinlian Cable Factory’s Yinchuan Sales Office quoted 130 yuan per plate for Changcheng BV2.5mm2 cable. When the unannounced visit group requested to go to the warehouse to see the goods, it was rejected by the boss and said that it could only be given to see samples. In an electric wire and cable shop named Hongri, the owner heard that the customer wanted to buy a BV 2.5mm2 line. He immediately asked “what is the national standard or what?†and frankly stated the line of Yupu’s wire in his shop. Not thick enough, self-proclaimed 2.5mm line is about 2.2mm, when the unannounced visits to the staff asked whether the clearance can pass, the boss frankly "the inspection will certainly not pass (off)."
Linkage counterfeiting: China's quality Wanli line with law enforcement agencies in Guangdong, China's quality Wanli Bank’s unannounced visits to the investigation team found that Guangdong Heshan Shaping Wire Factory is mass producing cables and cables that have not been certified by 3C. After unannounced visits to the evidence, the unannounced visits group reported the situation to Jiangmen Municipal Bureau of Quality and Technical Supervision. On January 6, 2011, the staff of China Quality Wanli Mingzang Unannounced Visiting Team visited the Shaping Wire Factory in Guangdong Heshan along with the law enforcement officers of the Jiangmen Quality and Technical Supervision Bureau to conduct law enforcement inspections and discovered the wire and cable products being produced on the factory production line and the wires in the warehouse. Cable products are not 3C certified products. Law enforcement officers sealed the workshop production line on the spot.
In Hubei Province, China’s quality Wanli Mingchawa unannounced visits group found through investigations and evidence that the 34th shop on Qingfen 2nd Road in Hankou sold a large number of counterfeit products from the second wire and cable factory in Wuhan.
The China Quality Supervision Bureau’s unannounced visits to the local industry and commerce departments informed the case and on January 11th, 2011, the investigation team’s personnel came to the store with raids and inspections.
The shop owner also vowed to claim that his product was genuine. It was not recognized as "false" until the second wire and cable plant in Wuhan City found the product counterfeit. But at the same time, he also argued, "The false ones are all other people wanting to get the job done." They also claim that selling their own clothes is "needs in the market."
While investigating the shop's counterfeit products, someone in the next-door shop ran off with a few coils of wire and was stopped by law enforcement personnel. After investigation, the wire was also a counterfeit product. At the same time, another employee of the shop fled the shop with the bill.
Regulating the market: People in the industry are worried that the products of their own registered trademarks have been infringed and counterfeited. Director Peng of Wuhan No. 2 Wire and Cable Factory stated that it was “very headacheâ€. He said: "The counterfeit products in the market are not exhausted and will never stop. It will have a great impact on the reputation of a company. If a company counterfeits its products, it will be eliminated by counterfeit products."
This is the so-called "bad money drives out good money." In the same way, the section of the Shanghai Panda Electrical Wire Factory, which was deeply detested by the infringements of counterfeiting and inferiority, expressed its great welcome to the China Quality Tour, which has been conducting unannounced visits to protect the intellectual property rights and crack down on fake and inferior products. The section called Panda Electric Wire Factory to set up an intellectual property protection department to passively take the initiative to attack counterfeits and counterfeits. However, due to fake and shoddy products, the “cost of counterfeiting and illegal costs are too low, resulting in the elimination of counterfeiting and counterfeiting,†making fake production and sales of counterfeits a strange phenomenon of “wild fire and spring breezeâ€.
The profit-making nature of businesses, the lack of corporate morality, and the cutting-edge workmanship for cost-saving pursuit of profits by the builders, coupled with the incomplete duties of individual law enforcement personnel, have enabled counterfeit and shoddy wire and cable products to move off the production line and onto the counter with great fanfare. Into the construction site, it laid a hidden danger for future safety.
At present, the status quo of China's wire and cable industry is not optimistic. The industry is in surplus, the structural contradictions are prominent, the supply of high-end products is insufficient (the foreign brands occupy 80% of China's wire and cable market), the quality of products is uneven, input and output is low, and the ability of scientific and technological innovation Inadequacies have had a great impact on the development of the wire and cable industry.
People in the industry pointed out that to standardize the market, we must first strengthen industrial planning and government guidance. We must manage and make good use of government investment. The competent authorities should strengthen supervision and supervision and inspection, standardize market competition order, and purify the market environment. Construction units must also strictly Good wire and cable quality mark.
Once there is no market and no market, naturally no one will come to fraud.
