China Enameled Copper and Aluminum Flat Wire Suppliers | ISO9001 Certified Factory Products
Enameled Flat wire is made of oxygen free copper or electrical aluminum rod, which are drawn or extruded by the specification mould. They are mainly used in the windings of electrical equipment such as transformer, reactor and etc. According to the different insulating paint, it can be divided into 6 categories:
- ⚡120 — Polyvinyl acetal / Self adhesive polyvinyl acetal enameled copper (aluminum) flat wires QQ/QQN
- ⚡130 — Polyester enameled flat wires QZ
- ⚡155 — Modified polyester enameled flat wires QZG
- ⚡180 — Polyester imide enameled copper (aluminum) flat wires QZY
- ⚡200 — Polyester imide / polyamide-imide composite enameled copper (aluminum) flat wires Q(ZY/XY)
- ⚡220 — Polyamide imide enameled copper (aluminum) wires QXY
- 🔶 Soft Copper Flat Wire — Complies with GB5584.2-2009. At 20℃, resistivity ≤ 0.017241 Ω·mm²/m, meeting different mechanical strength requirements.
- 🔷 Soft Aluminum Flat Wire — Complies with GB5584.3-2009. At 20℃, resistivity ≤ 0.02801 Ω·mm²/m. Film thickness options: thin film 0.06–0.11 mm or thick film 0.12–0.17 mm, depending on insulation requirements.
