Glass Insulated Nickel Clad Copper Conductor Heat Resistant Cables – Ninomiya TN200

Features

  • Smaller in diameter and lighter with the same allowable current, because the volume resistivity is 1/4 of nickel conductor.
  • Easy to process and wire, because it is softer than nickel conductor.
  • The thickness is 20-30 times of normal nickel-coated wire (1-5 μm). (Nickel vs. copper area ratio: approx. 28:72.)
  • The conductivity varies depending on changes in temperature. Even if used continuously under a temperature of 220℃, the conductivity varies only slightly.
  • The tensile strength varies only slightly when even if used under a temperature of 220℃.
  • Using nickel as the surface material, far more resistance to corrosion than copper wire.

Glass-insulated nickel-clad-copper conductor heat-resistant wire (TN200) is made of nickel-clad-copper wires which are flexible and highly resistant to heat and corrosion, and covered with glass fiber. Maximum operation temperature of this series is 220℃.

Construction

  • Conductor
    Several nickel-clad-copper wires (NPC) are stranded to make a conductor.
    Construction of the conductor is shown in below table. NPC has lower conductor resistance and more flexibility than nickel wire.
  • Insulator
    Conductor is double served with glass evenly (if the nominal sectional area of the conductor is 8.0 Sq. or more, braided with glass-yarn instead of having the serving process), braided with glass-yarn, and baked with silicone varnish on the surface to make an insulator.
  • Color
    The standard is two red-spiraled stripes on the white ground.

Applications

Widely used as lead wires of electric heaters or wirings in high-temperature equipments where, especially resistance to heat and corrosion is required. Characteristics
