Enameled Copper( Aluminum) Rectangle Wire

Short Description:

Enameled rectangular wire is made of oxygen free copper or electrical aluminum rod, which are drawn or extruded by the specification mould. It is the baked winding wire with multiple -layers of insulating paint after annealing softening treatment. They are mainly used in the windings of electrical equipment such as transformer, reactor and etc.

Conductor Material

Enamelled flat wire with soft copper flat wire in accordance with the provisions of GB55842-2009, 20℃ resistivity ≤0.017241 ω ·mm²/m, according to different mechanical strength requirements.

Soft aluminum flat wire for enamelled flat wire is in accordance with the provisions of GB/T 55843-2009. 20℃ resistivity ≤0.02801 ω ·mm²/m, according to different insulation requirements, can use thin film 0.06 ~ 0.11mm or thick film 0.12-0.17mm.

The thickness of self-adhesive layer of hot-bonded enamelled flat wire is generally 0.03 ~ 0.06mm. Our company adopts dielectric loss meter to monitor.

According to different mechanical strength requirements, the nonproportional extension strength Rp0.2 of half hard copper conductor is as follows:
C1Rp0.2(>100-180)N/mm2, C2Rp0.2(>180-220)N/mm2, C3Rp0.2(>220-260)N/mm2.

We can manufacturer according to technical specification provided by WIDE APPLICATION OF ELECTROMAGNETIC WIRE COATING PRODUCTS

 At present, the application of electromagnetic wire coating products has greatly increased the consumption of electromagnetic wire with the acceleration of the pace of China's modern industrial construction and the rapid growth of export products. The enameled wire and electromagnetic wire mainly use the insulating electrostatic powder coating. At present, they are mainly used in the insulating oxide film electromagnetic wire instead of the concentrated sulfuric acid treatment of aluminum wire, and can also be used in the enameled paint of insulating paint coating on-line.

Because the coating thickness of general powder coating is applicable to the circular wire with the diameter of more than 1.6m m or the flat wire with the width of more than 1.6mm × 1.6mm, and the insulating coating with the thickness of more than 40 μ m, it is not applicable to the coating requiring thin coating. If the ultra-thin powder coating is used, the thickness of 20-40 μ M can be achieved. However, because of the cost of coating processing and the difficulty of coating, it can not be widely used. When the film thickness is too thick, the flexibility and other functions of the film are reduced, which is not suitable for products with too large bending angle of metal wire. Because of the limitation of film thickness, too thin wire is not suitable for powder coating technology.
