Silicone-rubber insulated wire (SR series, R-LK) is a tin-coated wire coated with silicone-rubber. SR series is manufactured based on the NINOMIYA Standards. There are five types in the series, rated at 600V, 300V, 1500V, 3300V and 6600V respectively. R-LK series is type-approved, conforms to the regulations of Electrical Appliance and Material Control Law and rated at 600V. Maximum operating temperature of both series is common at 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). Composition 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 coated with silicon-rubber evenly with thickness shown in below table to make an insulator.
  • Color
    Color varies depending on the type of insulator. The standardized color is white. Black, red, green, yellow, brown, blue and gray are also available.

Applications

Widely used in various areas. Examples: wirings in moderate high temperature (180 ℃ or below) environments, lead wirings, and moving parts wirings where flexibility is required.
