FAQ

FAQs
  • Q: How to choose the right wire for high-temperature environments?
    加 Created with Sketch.
    形状 Created with Sketch.
    A: For high-temperature environments, it is recommended to use fluoroplastic wires (e.g., UL1330, 200℃) or silicone rubber wires (e.g., UL3251, 250℃).
  • Q: Which wires are suitable for automotive or new energy vehicle internal wiring?
    加 Created with Sketch.
    形状 Created with Sketch.
    A: Wires for automotive electrical systems (e.g., QB-B, FLRY-A) and wires for electric vehicles (e.g., EV XLPE WIRE) are specifically designed for internal vehicle wiring.
  • Q: Which wire should be used for electronic equipment requiring anti-interference?
    加 Created with Sketch.
    形状 Created with Sketch.
    A: PVC sheathed wires with Al-Mylar shielding (e.g., UL2464, UL2517) can effectively resist external electromagnetic interference.
  • Q: Which wires have excellent oil and climate resistance?
    加 Created with Sketch.
    形状 Created with Sketch.
    A: Cross-linked PE wires (XLPE) and fluoroplastic wires (FEP) typically possess excellent oil and climate resistance due to their material properties.
  • Q: How to distinguish PVC electronic wires with different temperature ratings?
    加 Created with Sketch.
    形状 Created with Sketch.
    A: You can distinguish them by their UL style numbers, for example, UL1571 is rated for 80℃, while UL1015 is rated for 105℃.
