Three-layer Insulated Copper Wire (Direct Welding) — 0.7mm Diameter, 100m

Direct-welding three-layer insulated copper wire, 0.7mm diameter supplied on a 100m spool. The copper conductor is covered with three insulation layers and is designed for direct welding without the need to scratch the insulation. Built for toughness — it resists breakage during winding and retains a natural color finish. Ideal for fabricating transformers, inductors, motors, speakers, potentiometers and other magnet wire uses where electrical current is converted into magnetic fields. Widely applied in transformer and coil production, motor and solenoid winding, speaker coil manufacture, electromagnets and insulated wire coils.
