The Number of Enterprises in Enameled Copper Clad Aluminum Wire Is Increasing Year By Year
At present, Enameled Copper Clad Aluminum Wire(XINYU-ENAMELEDWIRE) are mainly used in low-voltage power cables. Although medium-voltage cables are also involved, the number is very small. Like wires for electrical equipment, the main reason why enameled copper clad aluminum wires are used as conductors in power cables is also due to the rise in copper prices and the fact that enameled copper clad aluminum wires are superior to aluminum-core cables in joint links. Internationally, standards such as UL1581, UL1072 and UL83 in the United States have made corresponding regulations on the performance and wire gauge of enameled copper clad aluminum wire as a power cable conductor, but there are few examples in actual application. Up to now, enameled copper clad aluminum wire has only enterprise standards.
In the past three years, wire and cable with enameled copper clad aluminum wire as a conductor have been widely used. At the same time, many enterprises have entrusted their products to the national wire and cable quality supervision and inspection centre for inspection. As of the end of April 2008, nearly 40 cable enterprises have entrusted the inspection centre to carry out type tests. As far as the inspection situation of enterprises is concerned, the products currently submitted for inspection are mainly concentrated in power cables, and mainly cables under 10 kV, of which 1kV cables account for about 80% of the total number of products submitted for inspection, and 10kV cables account for about 20%.
It is precise because of the above factors that the number of enterprises producing enameled copper clad aluminum wire in China has a trend of increasing year by year. From 2005 to 2006, there were only about 3,500 manufacturing enterprises in the country, to 2007, dozens of enterprises have already entered or are preparing to enter this product field.
