Enamelled rectangular copper wire Thickness 1.70mm is an insulated copper electrical conductor used in motors, transformers and other electromagnetic equipment. When wound into a coil and energized, magnet wire creates an electromagnetic field.

Conductor thickness: 1.70 mm

Conductor width: 2.10-3.20 mm

Thickness Tolerance: ±0.03 mm

Width Tolerance: ±0.06 mm

Single Insulation Thickness: Min 0.015 mm

The present trend of the appearance structure of consumer electronics is designed to be"light,thin, short and small". Well Ascent high-precision and small enameled flat copper wire has excellent quality and performance, it can be met the requirement of flattening, light-weight,low power consumption and high performance.

Features and advantages of enameled flat copper wire

In the same winding space, the cross-section area of flat copper wire is large than round copper wire. It has higher space factor, smaller resistance and can through larger current if coils are made by flat wire,and prevent the over-heat of electronics products. It is more applicable to high load demand.

When the cross-section area is larger, it can improve the skin effect and reduce losses of high frequency current. While the flat wire has a good heat dissipation performance, it is more applicable to high frequency transduction.

Flat copper wire had the advantages of small vibration, low noise and good electromagnetic when undertake high current.

It can be improved the space factor of coil, good performance of electric field efficiency when coiled.
