Glass Insulated Nickel-Conductor Heat Resistant Cables – Ninomiya NI-GB

Glass-insulated nickel-conductor heat-resistance wire (NI-GB) is made of nickel wires which are highly resistant to heat and corrosion, and covered with glass fiber. Maximum operating temperature of this series is 220℃.

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. Nickel-coated annealed copper wire also can be a conductor.
• Insulator
  Conductor is double served with glass evenly, braided with glass-yarn, and baked with silicone varnish on the surface to make an insulator. If nominal sectional area of the conductor is 8.0 Sq. or more, it is double braided with grass-yarn instead of having the serving process.
• Color
  Color identification is made by coloring silicone varnish, and spiraling glass-yarn braid and colored glass fiber in stripes at the outermost. The standard is red-spiraled stripes on a 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.
