Professional Industry Features

  • Advanced Silicone Insulation: Engineered to maintain mechanical integrity and dielectric strength under continuous heat stress of up to +180°C (356°F), while remaining pliable during sub-zero operations as low as -40°C (-40°F).
  • 1500V High-Voltage Safety: Specifically designed for the modern EV architecture which requires higher voltage ratings to support faster charging and more efficient power delivery compared to standard 600V automotive wires.
  • Superior Flexibility: The conductor utilizes a high-strand count design, significantly reducing the bending radius. This allows for easier routing through the complex and cramped spaces of a vehicle’s chassis and engine bay.
  • Environmental & Chemical Resistance: Fully resistant to automotive fluids including oils, fuels, and coolants. The silicone jacket provides excellent protection against ozone aging and UV exposure.
  • Flame Retardancy: Compliant with ISO 6722 vertical flame tests, ensuring maximum safety for the vehicle’s high-voltage electrical network.
