Heat Resistant Glass Cables – Ninomiya GB

Heat-resistant glass wire (GB) made of heat-resistant tin-coated wires and covered with glass fiber. Maximum operating temperature of this series is 180℃.

Construction

• Conductor
  Basically conductor is a stranded wire made of several tin-coated annealed copper elemental wires which correspond with JIS C 3152 (Tin-coated annealed copper wires).
  Construction of the conductor is shown in below table. Nickel-coated annealed copper wire or silver-coated annealed copper wire also can be a conductor.
• Insulator
  Conductor is double served with glass evenly, braided with glass-yarn, and baked with heat-resistant 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 heat-resistant varnish. The standardized color is white. Black, red, green, yellow, brown and blue are also available

Applications

Widely used in various areas as low-cost heat-resistant wires. Examples: lead wirings in electric heaters and wirings in other high-temperature equipments.
