IEC60947 Wire Clamping Damage To And Accidental Loosening Of Conductors Flexion Tester 75mm
Product Introduction
This testing machine is also called the test apparatus for checking damage degree of wire which confirms to standards IEC60947-1 clause 8.2.4.3 ,figure 1 table 5. This compliance is used for judging whether the design and the structure of the clamping screw terminal is correspondent with the requirement of non over-damage to the wire.
