20 - 56 AWG Varnished Copper Magnet Wire super Fine Copper Wire Insulated
Enamelled copper wire has very obvious advantages.
1. It has excellent electrical conductivity, which can transmit electrical signals in the circuit with little loss, thereby improving the performance stability and data transmission capacity of the device.
2. The enamelled copper wire has good corrosion resistance, which can avoid the influence of oxidation and corrosion on the wire during long-term use.
3. Enamelled copper wire can also be fireproof, because the paint film can play a role in fire prevention. In enamelled copper wire, the effect of polyurethane paint film is particularly remarkable.
