Professional Industry Features

  • Triple-Layer Insulation System: This cable features a specialized composite construction. The inner silicone rubber provides high dielectric strength, while the middle fiberglass braid acts as a mechanical reinforcement. The outer silicone jacket ensures a gas-tight seal and protection against moisture.
  • 10,000V High-Voltage Reliability: Specifically engineered as high-tension leads for ignition modules. The reinforced wall prevents dielectric breakdown even under consistent high-voltage pulses.
  • Extreme Thermal Stability: Designed to maintain mechanical flexibility and electrical integrity across a wide thermal spectrum, from deep cryogenic environments at -60°C (-76°F) to constant high-heat exposure at +200°C (392°F).
  • Advanced Conductor Protection: By using Tinned Copper or Nickel-plated Copper, the conductor remains highly resistant to oxidation and corrosion, ensuring long-term reliability in humid or high-temperature kitchen and industrial environments.
  • Optimized for Precision Ignition: The fiberglass braiding layer adds significant tensile strength and cut-through resistance, protecting the wire from damage during routing through tight appliance chassis.
