This testing machine is also called the test apparatus for checking damage degree of wire which confirms to UL486 standard. 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. Besides, it is also used to check whether the clamping screw terminal can bear the stress during the process of normal usage.
The testing times can be preset before the test, and the compliance stops automatically with the alarm when the testing times are reached.
The major difference between CL-2 and CL-4 is that the CL-4 has two stations. The height can be reached to a maximum of 500mm and the maximum rotating weight is 22.7 kg and the maximum tensile weight is 578N. It depends on the actual use to choose them.
