ROUND COPPER FLEXIBLE STRANDED WIRE

  Usage
The copper stranded wire is used as flexible jointing wire in electric transmission and distribution appliance(such as volt transformer﹜electric stove)﹜electronic equipment and thyristor etc,it also could be used as grounding wire in electric working.

Technique performance
1.The copper flexible stranded wire is made is super-quality round copper wire or tining round copper wire,this product has passed tenacity processing,so the complete-product is soft and its outline is beautiful.
2.The DC electrical resistivity(20⊥)of copper braided wire is lower than 0.0182次.mm2/m,the DC electrical resistivity (20⊥)of tining copper braided wire is lower than 0.0193次.mm2/m.
3.The technique standard of this product conforms with GB12970.2-1991 Notes:if having special demand,customer please contact our corporation directly.
