Enameled Flat wire is made of oxygen free copper or electrical aluminum rod, which are drawn or extruded by the specification mould.They are mainly used in the windings of electrical equipment such as transformer,reactor and etc.According to the different insulating paint, it can be divided into 6 categories:

120 polyvinyl acetal / self adhesive polyvinyl acetal enameled copper (aluminum ) flat wires--QQ/QQN

130 polyester enameled flat wires--QZ

155 modified polyester enameled flat wires-QZG

180 polyester imide enameled copper ( aluminum ) flat wires--QZY

200 polyester imide / polyamide-imide composite enameled copper( aluminum ) flat wires--Q(ZY/XY)

220 polyamide imide enameled copper ( aluminum ) wires--QXY

Production scope

Conductor thickness--a:0.80-5.60mm

Conductor width--b:2.00-16.00mm

Conductor width ratio: 20:1

Conductor material

Soft copper flat wire of enameled flat wire complies with the provisions of GB5584 2-2009 , when 20℃ , resistivity ≤0.017241Ω.mm²/m ,according to different mechanical strength requirements.

Soft aluminum flat wire of enameled flat wire complies with the provisions of GB5584.3-2009,when 20℃,resistivity≤0.02801Ω.mm²/m.According to different insulation requirements,can choose thin film from 0.06 to 0.11mm or thick film from 0.12 to 0.17mm.The thickness of hot adhesive enameled flat wire self-adhesive layer is generally 0.03 to 0.06mm.Our company monitor the thickness with dielectric loss meter.

The thickness of hot adhesive enameled flat wire self-adhesive layer is generally from 0.03 to 0.06mm.Our company monitor the thickness with dielectric loss meter.
