Annealed Bare Copper Conductor

Bare copper annealed wire is what we commonly call soft copper wire, that is, annealed soft wire, which is the wire after annealing and softening of hard bare copper wire. Bare copper annealed wires include annealed single wires, annealed parallel wires, and annealed stranded wires.

Compared with the bare copper hard wire, the bare copper annealed wire has obvious advantages, mainly having the following characteristics:

1. The carrying capacity of bare copper annealed wire is larger than that of hard copper wire.

Under the same cross-section, the surface area of soft copper wire is much larger than that of hard copper wire. Due to the skin effect of alternating current (when there is alternating current or alternating electromagnetic field in the conductor, the current distribution inside the conductor is uneven, and the current is concentrated in the "skin" part of the conductor, that is to say, the current is concentrated in the thin layer on the outside of the conductor. conductor surface, the greater the current density), so the carrying capacity of the soft copper wire is larger than that of the hard wire. In addition, due to the large surface area of the soft copper wire, its heat dissipation effect is better than that of the hard copper wire.

2. The softness of bare copper annealed wire is better than that of bare copper hard wire.

3. The surface of the bare copper annealed wire is bright, but the hard wire is too dull.

4. The resistivity of the bare copper annealed wire is lower than that of the hard state, that is, the impedance is smaller.

Bare copper annealed copper wire is widely used in electronics, communication, electric power and other fields, among which it is mainly used in power equipment such as inductor coils, transformer coils, motor coils, generator coils, etc., in electronic products such as mobile phones, tablet computers, televisions, etc. Bare copper annealed wires are also required in the manufacturing process.
