• The high space factor makes it possible to produce smaller and lighter electronic motor products that are no longer limited by coil size.
• Increased density of conductors per unit area allows for small size and high current products.
• Better heat dissipation performance and electromagnetic effect.
• Thickness: The minimum thickness of conductor reaches 0.09mm.
• Large width to thickness ratio: maximum width to thickness ratio is 1:15.
• Using independent innovative technology and special production process, the production of enameled copper small flat wire has better performance and heat resistance level reaches 220℃.
