Electrical Bare Copper Rectangular Wire

---

Introduction：Electrical copper rectangular wire is extruded or drawn from oxygen-free copper rod with certain specification mould. It can be used as finished product as well as semifinished product. Electrical copper Rectangular wire is widely applied in electrical machines, transformers, reactors and similar electrical instruments.

Production Range：

Electrical Copper Rectangular Wire
Narrow side size a: 0.90mm—5.60mm

Wide side size b: 2.00mm—16.00mm

Material：
Electrical copper rectangular wire should conform to GB5584.2-2009，the resistivity(20℃)is no more than 0.017241Ωmm²/m

Tensile strength and elongation of electrical copper rectangular wire should conform to the table as follows：

Nominal Size /mm	Soft Copper Rectangular Wire (TBR)		Hard Copper Rectangular Wire in Status H1 (TBY1)		Hard Copper Rectangular Wire in Status H2 (TBY2)
