Premium Construction & Compliance

  • Conductor: Silver-plated/Nickel-coated copper strands (e.g., 19/0.26mm) – enhanced oxidation resistance at extreme temperatures
  • Insulation: Impregnated phlogopite mica tape + fiberglass backing:
    • Fire Resistance: Withstands 900°C for 3 hours (per IEC 331/BS 6387 CWZ) with zero flame propagation
    • Chemical Immunity: Resists acids, oils, solvents, and radiation up to 10^(9) Rad (excludes sulfuric acid)
  • Certifications: Complies with UL 5128/UL 5335 (AWM), RoHS, REACH, IEC 60335-1 (household safety)

Critical Technical Data

Parameter Specification

Continuous Temp -80°C to +500°C (conductor)

Peak Temp +1000°C (short-term)

Voltage Rating 500V AC max (300V AC continuous)

Dielectric Strength >1.5 kV/layer (IEC 371-2)

Insulation Resistance >20 MΩ·km (1000V DC at 20°C)

Flexibility Bend radius ≥6× cable diameter

Competitive Advantages

  • Unmatched Fire Survival:
    • Self-extinguishing (VW-1/UL 94), zero toxic fumes – critical for mass transit/aircraft wiring
    • Maintains dielectric integrity at 1000°C (50% dielectric strength retention at 700°C)
  • Longevity & Reliability:
    • >10,000 hours service life at 500°C (vs. silicone’s 5,000 hours)
    • Halogen-free (IEC 60754-1), safe for enclosed spaces
  • Eco-Safety:
    • Non-toxic, odorless silicone binder – complies with FDA 21 CFR for household appliances

Target Applications

  • Industrial Heating: Furnace sensors, glass plants (≤1000°C environments)
  • Critical Infrastructure: Nuclear reactors (radiation-resistant)
  • Household Appliances: Ovens, dryers (IEC 60335-1 compliant ≤500V AC)
  • Transportation: Shipboard cables, aircraft engine wiring (FAR 25.853 fireproof)

Customization Options

  • Shielding: SS304 braid or aluminum foil for EMI-heavy environments (e.g., VFD motors).
  • Insulation Layers: 1–3 mica tape wraps with 20–50% overlap (customizable)
  • Packaging: 30m rolls (standard) or custom lengths up to 1000m.
  • Certifications: ATEX/IECEx reports for Zone 1 hazardous areas.
