2UEWF/H 0.04mm Green Color Super Thin Magnet Wire Enameled Copper Wire For Motor
This green enameled copper wire belongs to the category of ultra-thin wire, which gives it unique advantages in the field of information transmission. Ultra-fine wire is known for its small size. Its filament diameter has better flexibility and plasticity, making it more convenient to be used in various precision equipment. The advantage of ultra-thin wires is that they provide higher signal transmission efficiency and bring stronger performance advantages to the field of information transmission.
In the field of information transmission, green enameled copper wire is widely used in the internal connection and signal transmission of various electronic equipment. Its unique green appearance makes identification easier and clearer during equipment maintenance and troubleshooting.
Compared with other ordinary wires, the green enameled copper wire looks distinctive, and users can easily distinguish it from other wires, thereby improving work efficiency.
The paint film of this enameled copper wire is made of polyurethane, which gives it excellent solderability.
Enameled copper wire, as a customized wire launched by our company, has outstanding advantages in the field of information transmission. Its unique color, excellent weldability, high temperature resistance, and ultra-thin wire characteristics make it the material of choice in the fields of electronic equipment manufacturing and communications.
Our company also provides other colors of enameled copper wire for customers to choose from to meet the needs of different application scenarios.
We will always be committed to providing customers with high-quality enameled copper wire to ensure the stability and reliability of equipment in information transmission.
