Professional Performance Features

  • Extreme Thermal Integrity: Specifically engineered for sustained performance in ultra-high-heat industrial environments. The composite structure of Mica tape and Fiberglass braiding ensures the wire remains operational at constant temperatures up to 450 degrees Celsius (842 degrees Fahrenheit).
  • High-Level Fire Survival Rating: This wire serves as a critical safety component for emergency systems. It can withstand direct flame contact at 800 degrees Celsius (1472 degrees Fahrenheit) for over 90 minutes, ensuring that essential control and power signals are maintained during a fire.
  • Superior Material Science: By utilizing high-purity Nickel-plated Copper or Pure Nickel conductors, the wire eliminates the risk of conductor oxidation and brittle failure which typically occurs in standard copper wires at temperatures exceeding 200 degrees Celsius (392 degrees Fahrenheit).
  • Mechanical Reinforcement: The specialized fiberglass braiding layer provides significant protection against mechanical abrasion and surface wear, protecting the delicate mica insulation during routing and installation.
  • Chemical and Environmental Resistance: The inorganic nature of the insulation materials provides excellent immunity to moisture, oils, and most industrial solvents, significantly extending the service life in harsh chemical and petroleum environments.
