( Industry news] Cable products in the sampling results gouxuechao P wire and cable market in tianjin, the competition heats up won't be surprise, but that is only confined to the traditional wire and cable market. Wire and cable industry in China after years of rapid development has formed a considerable scale, but due to the production capacity is greater than the demand, a supply glut. And technical content is not very high, for some it is hard to meet the special demand, based on this situation, special cable market is stand out, and the problem of the quality of the wire and cable is becoming more and more people concern! In order to further improve product quality, and promote the healthy development of the industry, the state administration of quality supervision, inspection and quarantine recently to the supervision and spot check the PVC insulated cable wire products. Involved in selectiving examination in Beijing, tianjin, hebei, henan, shandong, jiangsu, zhejiang, anhui, hunan, hubei, guangdong, sichuan, liaoning and other provinces and municipalities directly under the central government enterprises producing the kind of product. Spot check result shows, product sampling percent of pass is %, qualified products. In order to further improve product quality, and promote the healthy development of the industry, the state administration of quality supervision, inspection and quarantine recently to the supervision and spot check the PVC insulated cable wire products. Involved in Beijing, tianjin cable selectiving examination, hebei, henan, shandong, jiangsu, zhejiang, anhui, hunan, hubei, guangdong, sichuan, liaoning and other provinces and municipalities directly under the central government enterprises producing the kind of product. Spot check result shows, product sampling percent of pass is %, qualified products. Spot check report, wuxi jiangnan cable co. , LTD. , the colorful card, the second wire and cable co. , LTD. , wuhan flying crane CARDS, cable factory in yantai yantai mountain, hangzhou cable co. , LTD. Yong tong card and Phelps dodge ( Yantai) Cable co. , LTD. , the production of PVC insulated cable wire products quality is better. General administration of quality supervision, inspection and quarantine in selectiving examination report pointed out that at the same time, in selectiving examination found that five main quality problems. One is the voltage test does not accord with a standard to ask. It is understood that the standard provisions of the state, for a/V voltage level, PVC insulated cable wire products flooding hours in V ac voltage bligh minutes without breakdown. This spot has a product by the breakdown voltage test. The second is insulation tensile strength is not qualified. Insulation tensile strength is an important project the insulation of the cable wire. There are three kinds of the spot check product the insulation of the tensile strength is lower than the national standard requirements. Three is the conductor resistance does not accord with a standard to ask. As the assessment of cable wire conductor material and cross section is in accordance with the requirements of the important indicators, conductor resistance is unqualified products will accelerate the aging of wire insulation. There are two kinds of the spot-check product conductor resistance exceeds the national standard requirements, mainly in product dc resistance, increased by the loss of the current on hot wire. Fourth, insulation resistance is unqualified. There are two kinds of the spot-check product insulation resistance is lower than the national standard requirements, the main reason is that the insulation of the cable wire materials can not reach the requirements of the standard. Five is non-standard. The selective examination marks is unqualified, there are three kinds of products mainly include no marked 'name, type, rated voltage', etc.
