Rectangular wire
Pure rectangular copper wire (flat wire) with a thickness of 1.3 mm or more & Transformer copper wire with no impurities attached.
発生源
Since the flat wire is mainly used in high-voltage transformers, it is often generated from the high-voltage transformer that is removed when the factory is dismantled, or from the transformer manufacturers.
原料になるまでの工程
The recovered flat wire is pressed or cut and delivered to the manufacturer as a metal raw material after checking whether solders have been segregated or if a large amount of oil remains.
製造業者
Flat wire delivered to the manufacturer is melted and cast in an electric furnace or reverberatory furnace. The cast ingots are remanufactured as semi-finished copper plates and strips by techniques such as rolling and extrusion.
Such semi-finished products are used for electric wires of infrastructure equipment such as electric power and communication and are recycled into various products such as terminal parts for mobile phones and connector parts for sensors.
