Conductors and Insulators

  • conductors: Gold, sliver, copper, aluminum
  • insulators: Teflon, mica, glass, rubber-like polymers
  • Different types of insulators have different properties. Such as high thermal resistance, resistance of pressure, and insulating strength, which can fit different requirements of working environments. Also for different conductors have different properties of electric conductivity.
  • temperature: the high temperature of working environment will lead insulators to broken easier than usual.

  • tensile strength: for example, Unit cross-sectional area of insulating material can withstand the tension, for example, cross-sectional area per square centimeter of glass can withstand the pull of Newton 1400.
