    SL-7609 Series Tracking Test Chamber

    SL-7609 Series Tracking Test Chamber

  • detailed description
  • SL-7609 Series Tracking Test Chamber
     
    Standard
    According with IEC60112-2003, UL746, ASTMD3638-92, DIN53480, GB4706.1 and GB4207 standards.
     
    Used range
    This machine applies to determine the tracking index for electrics of various products, such as lighting, electronics, electric tools and instruments. It is also used for insulators, plastics, electric connectors and so on.

     

    Principle

    In moisture and impurity circumstance, leakage current of insulation will be produced between live parts of different polarity, or between live parts and grounding metals. The electric arc produced will result in short-circuit. This tester is to simulate these conditions, and to determine the tracking index of materials.
