Cheap PriceList for Magnetic Copper Wire - EIW 180 Polyedster-imide 0.35mm Enamelled copper wire – Ruiyuan

The chemical contents of EIW is Polyedster-imide, which is the combination of Terephthalate and Esterimide. At operating environment of 180C, EIW can maintain good stability and insulating property. Such insulation can be well attached to conductor(adherence).
1，JIS C 3202
2，IEC 60317-8
3，NEMA MW30-C

1. good property in thermal shock
2. Radiation resistance
3. Excellent performance in heat resistance and softening breakdown
4. Excellent thermal stability, scratch resistance, refrigerant resistance and solvent resistance
Applied standard:
JIS C 3202
IEC 317-8
NEMA MW30-C

Our enameled copper wire can be applied to various devices such as heat-resistant motor, four-way valve, induction cooker coil, dry-type transformer, washing machine motor, air conditioner motor, ballast, etc.
Test method and data for adhesion of EIW enameled copper wire are as follows:
For enameled copper wire with diameter less than 1.0mm, jerk test is applied. Take three strands of samples with a length of about 30cm from the same spool and draw marking lines with a distance of 250mm respectively. Pull sample wires at a speed of more than 4m/s till they break. Check with the magnifying glass as specified in the table below to see if there’ s any cleavage or crack of exposed copper or loss of adhesion. Within 2mm won’ t be counted in.

When the diameter of conductor is more than 1.0mm, twisting method (Exfoliation Method) is applied. Take 3 turns of samples with a length of about 100cm from the same spool. The distance between the two chucks of the testing machine is 500mm. Then twist the sample in the same direction at one end of it at a speed of 60-100 rpm per minute. Observe with naked eyes and mark down the number of twists when there’ s exposed copper of enamel. However, when sample is broken during twisting, it’ s a requisite to take another sample from the same spool to continue the test.
