Product introduction:

        Enamelled flat wire is a winding wire made of oxygen-free copper rod or electrical round aluminum rod after being drawn or extruded by a specification mold. After annealing and softening, the drawn bare wire is painted and baked several times. It is mainly used in windings of transformers, reactors and other electrical equipment.

Conductor material:

        Soft copper flat wire for enamelled flat wire conforms to the provisions of GB5584.2-2009, and the resistivity at 20 ℃ is ≤ 0.017241 Ω · mm ²/ m. According to different mechanical strength requirements.

        Soft aluminum flat wire for enamelled flat wire shall comply with the provisions of GB/T 5584.3-2009. Resistivity at 20 ℃ ≤ 0.02801 Ω · mm ²/ m. According to different insulation requirements, thin paint film 0.06-0.11mm or thick paint film 0.12-0.17mm can be used.

        The thickness of the self-adhesive layer of the thermally bonded enamelled flat wire is generally 0.03~0.06 mm. Our company uses a dielectric loss meter for monitoring.

Please contact us if you have any requirements on the film thickness.

According to different mechanical strength requirements, the specified non-proportional extension strength Rp0.2 standard range of semi-hard copper conductor is as follows:

C1Rp0.2（>100～180）N/mm ²、 C2Rp0.2 (greater than 180 ～ 220) N/mm ²、 C3Rp0.2 (greater than 220~260) N/mm ²。

It can be processed and customized according to customer technical requirements.
