The CHINGCUNG QY(F)-2/240 Enamelled Copper Wire is manufactured using high-purity oxygen-free copper and coated with a high-performance aromatic polyimide resin. This unique insulation layer provides exceptional thermal stability, allowing the wire to operate continuously at high temperatures (Class 240) and withstand extreme overloads.
This wire is specifically designed for applications where traditional polyester or polyester-imide wires fall short. It offers excellent resistance to radiation, extreme cold, and chemical corrosion, making it the premier choice for the most demanding winding environments.
| Extreme Heat Resistance Withstands cut-through temperatures up to 450°C, ensuring structural integrity under short-term overloads and high-temperature spikes. | Chemical & Solvent Resistance Highly resistant to diluted acids, alkalis, organic solvents, and refrigerants, suitable for hermetically sealed applications. |
| Radiation Resistance Maintains electrical properties even under gamma and beta radiation exposure, ideal for nuclear or medical equipment. | Mechanical Strength Superior abrasion resistance and flexibility (Mandrel winding test passed), reducing the risk of insulation failure during high-speed winding. |
