Silica-glass insulated nickel-conductor heat-resistant wire (TM450) is made of nickel wires which are highly resistant to heat and corrosion, wrapped with glass-mica-polyimide tape and coated with silica-glass fiber. Maximum operation temperature of this series is 400℃ for continuous use.

Construction

  • Conductor
    Basically conductor is a stranded wire made of several nickel elemental wires which correspond with JIS C 2532 (Electrical resistance wires, ribbons, and sheets for general use). Construction of the conductor is shown in below table.
  • Insulator
    Conductor is double wrapped with glass-mica tape, braided with silica-glass fiber, and baked with polyimide coating on the surface to make an insulator.
  • Color
    The standard color is dark brown of the polyimide coating. The color may vary (darker) depending on the baking temperature.

Applications

Being deasbestos wires, used as lead wires of electric heaters or wirings in high-temperature equipments where, especially high resistance to heat is required.
