High marks for instruction! Wire industry related standard for broken copper wire
Copper wire is the most important raw material or semi-finished product of wire and cable. The copper wire standard is the most widely referenced basic standard in the production standard of wire and cable. The performance standards of copper wire standard will affect the performance and quality of most wire and cable products. In particular, China has a large proportion of products, with reference to the European standards and other domestic standards, mainly in automobiles, wires, railway locomotives, cables, machine control cables and other varieties. In the face of the current energy shortage situation, material price soaring, strengthen the quality control of copper wire for wire and cable cost control and improve product performance, has important significance to reduce energy consumption, and the research and application of the new standard is a shortcut. The crystallization, the new EU standard setting for European companies long-term processing technology and experience of the comprehensive content, specific indicators, complete specifications, for the production of copper wire, test stage, has important guiding significance in trade links and use of links.
The EN13602 standard consists of bare copper single wire, multiple bare copper single wire, tin plated single wire, and multi tinned tin. Corresponding to China's standards GB/T3953 and GB/T4909, but the specific requirements are higher than our standards. On the material, the standard specifies the requirement for the analysis of the chemical content of metals. On the performance of the product, the mechanical properties of the copper wire not only specify the elongation rate, but also specify the tensile strength and bending requirements of flexibility. Especially in the way of product processing, for the first time, the products of multi wire drawing have been included in the standard, and the classification, performance and testing methods of long wire drawing products have been stipulated. The standard also specifies the requirements for the different packing requirements of the long copper wires of the stationary and movable disk take-up lines. The long copper wire is easy to be twisted into a bundle, the quality is uniform, the utility model is not suitable for short silk, has good bending resistance, and has high production efficiency, and is widely used for the conductor manufacture of electric equipment, cables and automobile cables. Long copper wire has a large proportion in the production of copper wire in europe. In Europe, long wire drawing machines are already signs for automobiles, cables and flexible cables for industrial machinery. The EN13602 standard has a major impact on the production, use and trade of copper wires and wires for international wires and cables, and the finished products of wires and cables.
In 2002, the European Union promulgated the product standard EN 13602 for copper wires for conductors. Its full name was copper and copper alloys - cold drawn round copper wires for the manufacture of electrical conductors. The promulgation of this standard, as a unified standard of the European Union and the national standards of Member States, has replaced the original national standards of Member States, such as DIN 40500 and BS 4109, which we are very familiar with.
