Copper stranded wire refers to a new type of composite conductor, which is made of high-quality low-carbon steel. After copper plating treatment, multiple single stranded wires are twisted according to certain rules. Copper stranded wire is a soft connecting wire for power transmission and distribution, electrical equipment (such as transformer and electric furnace), electronic and electrical equipment and thyristor components.
1. Copper plays the role of conducting weak current signal, and steel wire plays the role of support. According to different copper plating methods of steel wire, it is mainly divided into electroplating, coating, hot casting / dip coating and electroforming. The product not only has the strength and toughness of steel, but also has the good conductivity and corrosion resistance of copper. With copper
Compared with single wire, it has the advantages of low density, high strength and low cost. It is an updated product of traditional pure copper single wire.
2. The use of copper strands can reduce the operating temperature. Compared with the single strand with the same cross-sectional area, the strand has higher mechanical flexibility. It is widely used in high "Q" value lines.
3. The copper stranded wire is made of high-quality copper wire and tinned soft copper wire. After toughening treatment in the processing process, the finished product is soft and neat with beautiful appearance.
