Photovoltaic welding ribbon<\/a>The main raw materials are copper, tin and other non-ferrous metals. The copper-based materials required for photovoltaic welding strips are mainly TU1 oxygen-free copper wire and TU2 copper, and the copper content is required to be \u226599.99%. TU1 oxygen-free copper wire is a very mature product.<\/p>\n

There are many domestic manufacturers, prices are relatively transparent, supply is relatively sufficient, procurement is relatively easy, and the bargaining power of TU1 oxygen-free copper wire suppliers is not strong. According to the China Nonferrous Metals Processing Industry Association, China is the world's largest copper processing producer, although the scale of China's copper processing production enterprises is generally smaller than that of enterprises in Europe and the United States.<\/p>\n

along withPhotovoltaic modules<\/a>The broad prospects brought by the growth of production also include the production and use equipment of photovoltaic welding strips. At present, there are two main production processes for photovoltaic welding strips. One is to cut the wide flat copper strip into the required width through the slitting process, and then tin it after annealing; the other is to use calendering equipment to calender anneal and tin the copper wire. Although the cost of using the strip annealing process for welding strip processing is high, the loss is large, and the efficiency is low, it is also widely used by welding strip manufacturers because the yield strength of the calendering annealing machine does not meet the use standards of welding strip components in the early stage of the industry development.<\/p>\n

With the technological update of calendering equipment manufacturers, the new generation of calendering machines have integrated calendering and annealing, and the solder strip products made using this process can fully meet the use requirements of components and have been accepted and used by most manufacturers. Considering the continuous improvement of photovoltaic component production capacity, it is believed that this will also bring good development prospects to equipment manufacturers to a certain extent.<\/p>","protected":false},"excerpt":{"rendered":"
