Wire and cable in China, deputy director of Quality Supervision, Inspection Wu Changshun, in 2008 China wire and cable industry report by the General Assembly, said wire and cable can not be optimistic about the overall product quality,glue stick our level of quality wire and cable products decreased year by year, product quality at a low hover state .
CCC 2004-2007 certified product sample test results show that sample testing of wire and cable products, the passing rate has remained at 80% to 90%; in more stringent Southern Power Grid Company to apply short-listed suppliers XLPE Dianlan sampling in 4 consecutive years ,2004-2007 qualified rate of 60% to 80%, respectively.glue gun Failed project, the structure accounts for the main part of the problem size, but also identifies the signs and insulated core color, electrical properties, mechanical properties such as insulation and sheathing aspects.
Wu Changshun reluctantly said: "In fact, the test items are the basic indicators of wire and cable products and very easy to control, but after years of industry correction did not improve. According to Wu Changshun introduced a Trade and Industry Bureau had 36 companies of the 60 samples the random sampling of the market, the results of 24 companies failed, corporate compliance rate was 33.3%, 50 samples failed, the product pass rate was 16.7%.
Continues to remain low for the level of product quality, Wu Changshun concerns: "In recent years, annual production of the domestic cable industry billions of dollars of wire and cable products, these products are widely used in industries of national economy, major projects and key national projects. These wire and cable products for a long period of time will be the normal operation of the national economy, the functioning of the implementation of major projects, social security and stability have a significant impact, industry, large area, a substantial decline in the quality of products can not but worry us. "
The circulation of substandard products currently on the market, the conductor cross-section cut corners, using low-quality insulating and sheathing materials, rubber wire insulation and sheathing materials of low gel content was accounted for a significant portion of such issues.
"Product quality is not a qualified manufacturing enterprises can not make products, but the entire industry overcapacity led to disorder and vicious competition, disorderly, vicious competition and forces firms to adopt cutting corners, substandard materials using low-cost ways to reduce costs pressure to maintain profit margins. "Wu Changshun can not say the product quality of the important reasons. For example, the China Southern Power Grid in the testing process found that many businesses fail just because the product uses a low-quality raw materials, production capacity and technological level with nothing to do. Compliance is the production of quality raw materials, wires and cables passing a prerequisite for bringing a range of product quality problems. If the business can build its own characteristics consistent with the raw materials into the factory inspection procedures, enhancing its detection ability, the quality of products will be well improved.
Showing that the fundamental factor is the low quality "man-made", that is low-cost twisted sense of quality. Therefore, the enterprise management industry to eliminate the existence of the many irrational factors, from the sense of the direction of the correction to improve the legal awareness, establish a correct concept of business ethics and social responsibility.
Turn the timely management ideas, can fundamentally change the production of extensive quality control methods, but also depends on the specific implementation process. Therefore, the enterprise should the development, production and detection aspects of long-line technical talents of skills training and quality awareness training.
However, at present the industry perspective, with the capacity expansion is lagging behind the development of technical personnel, resulting in output per capita is responsible for rapid increase in short period of time, increasing the production of product quality risks. Meanwhile, the personnel shortage also speed up the flow of talent. However, due to inter-enterprise system, scale, level differences, caused by the frequent movement of the operation which they are often in a job running the state, is not conducive to sustained and stable production. Therefore, enterprises should develop a localized and stable technical personnel.
Weak sense only if the quality of enterprises under market pressure to reduce the yield of a moral bottom line, then the production of wire and cable business process behind the low degree of automation to improve the quality of products has become the Mishap.
Cable production process is long, and everything in shaping the dynamics of the process quality control is particularly important, alone the quality and experience of technicians very difficult to complete, require the help of advanced digital equipment.
First of all have wire and cable testing equipment measurement test. Is a measure of product quality testing equipment, the base scale, if the inherent errors will lead to follow-up the waste production process, and ultimately produce a substandard product. Wu Changshun, said: "Many companies purchase measuring equipment, testing equipment is not used to maintain the measurement test, but as a tool to meet the inspection authority. Appears to omit a process, reduce production costs, in fact, the sample was a serious waste of manpower and material, testing useless. "Second, effective monitoring should be equipped with devices, such as diameter measurement, the thickness of line tester and so on, to implement the provisions of the parameters of process documents, to ensure that documents and in-kind match requirement. In order to ensure the accuracy of detection and monitoring data should be advocated in the industry, automatic data collection using a computer testing equipment and production equipment, improve detection of data accuracy and traceability of measurements.
In addition, many found the quality of accident analysis, engineering design inappropriate or improper use of wire and cable products also contributed to shorten the life ahead of short-circuit breakdown occurs, deformation and other issues important to melt one of the reasons. Wu Changshun said, "For from the production of factors outside the enterprise should not be left unchecked, but should be possible with their own technology and experience to guide the engineering design and customer selection and rational design." And cable industry users To encourage the manufacturing of standard production, the quality and brand the first place, to face the objective enterprise manufacturing costs and the profits should be, face the lowest bid and other adverse consequences.
