Spark Tester complies with the standard requirement of UL1581-1990. It is indispensable test equipment for testing the quality of insulating layer with high voltage during the productive process of electric wire and cable. By placing the cable on the production line, it ensures that the deterioration, holes and errors that may occur in the cable insulation during production are detected quickly and with high precision.
With the spark tester, it can produce sine voltage waves up to 15kV at the mains frequency (50/60 Hz) and can be applied to cable insulation through bead electrodes along the 60 cm channel. Testing up to 200 meters per minute can be applied to the cable.
These series of testers have good humidity resistance and Strong ability of anti-interference. Thus to make sure the transformer can work reliably for a long term in the humid environment. It is equipped with Self-checking spark button which can check whether the equipment is in normal working station to make sure the accuracy of the test.
