Structure and Application
Copper stranded wire is a flexible connecting wire used in power transmission and distribution, electrical equipment (such as transformers, electric furnaces), electronic and electrical equipment, and thyristor components. It can also be used as a grounding wire for electrical work.
The copper stranded wire is made of high-quality copper wire and tin plated soft copper wire. During the processing, it undergoes toughening treatment, resulting in a soft, neat, and aesthetically pleasing finished product.
The DC resistivity of copper flexible stranded wire (20 ℃) shall not exceed 0.0182Q.mm/m, and the DC resistivity of tin plated copper stranded wire (20 ℃) shall not exceed 0.0234Q.mm/m.
This product's technical standard complies with GB12970.2-91
