Product Introduction

Comparison Dimensions	Enameled Flat Wire	Enameled Round Wire
Appearance and structure	Rectangular or flat square cross-section with wide width and small thickness	Circular cross section with uniform diameter
Electrical properties	Due to the large cross-sectional area and flat shape, the DC resistance is relatively low under the same cross-sectional area, it can carry a larger current and has a higher power transmission efficiency.	The current distribution of the circular cross section is relatively uniform, but in high current scenarios, the skin effect (current concentration on the surface of the conductor) may be more obvious and the resistance is relatively large.
Space Utilization	The flat square structure makes it more compact in the winding, with high space utilization, and is suitable for applications with strict volume requirements.	There will be some gaps when the windings are arranged in a circular structure, and the space utilization rate is relatively low.
Thermal performance	The flat shape increases the contact area with the air or heat dissipation medium, which improves the heat dissipation effect and is conducive to the long-term stable operation of the equipment.	The heat dissipation area is relatively small, and the heat dissipation performance is slightly inferior to that of flat wire
Processing and Application	The processing technology is relatively complex and is mainly used to manufacture transformers, motors and other electrical equipment that require large current, low resistance and compact space, such as the windings of power transformers, stators and rotors of large motors, etc.	The processing technology is relatively mature and widely used. It is often used in small motors, electronic transformers, inductors and other occasions where space requirements are not so stringent.

Precautions for use USAGE NOTICE

1. Please refer to the product introduction to select the appropriate product model and specification to avoid the failure to use due to the inconsistent characteristics.

2. When receiving the goods, confirm the weight and whether the outer packing box is crushed, damaged, dented or deformed; In the process of handling, it should be handled with care to avoid vibration to make the cable fall down as a whole, resulting in no thread head, stuck wire and no smooth setting out.

3. During storage, pay attention to protection, prevent from being bruised and crushed by metal and other hard objects, and prohibit mixed storage with organic solvent, strong acid or alkali. The unused products should be wrapped tightly and stored in the original package.

4. The enameled wire should be stored in a ventilated warehouse away from dust (including metal dust). Direct sunlight is prohibited to avoid high temperature and humidity. The best storage environment is: temperature ≤50 ℃ and relative humidity ≤ 70%.

5. When removing the enameled spool, hook the right index finger and middle finger to the upper end plate hole of the reel, and hold the lower end plate with the left hand. Do not touch the enameled wire directly with your hand.

6. During the winding process, the spool should be put into the pay off cover as far as possible to avoid wire damage or solvent pollution; In the process of paying off, the winding tension should be adjusted according to the safety tension table, so as to avoid wire breakage or wire elongation caused by excessive tension, and at the same time, avoid wire contact with hard objects, resulting in paint film damage and poor short circuit.

7. Pay attention to the concentration and amount of solvent (methanol and anhydrous ethanol are recommended) when bonding the solvent bonded self-adhesive line, and pay attention to the adjustment of the distance between the hot air pipe and the mold and the temperature when bonding the hot melt bonded self-adhesive line.
