Frequency Spark Tester

The utility frequency / line frequency / mains frequency Spark Tester.

We manufacture utility Frequency Spark Tester that designed for rewind and extrusion line to check defects in cable insulation.
The cable goes through a high-voltage bead chain electrode in the spark tester, and any insulation fault causes a spark from this electrode to the ground via cable core.
Any spark will be detected by spark tester electronics and marked as a fault.
The calbels is monitored by spark tester at your cable production line, any fault in cable insulation will be maked and an alarm will be generated，the mark can be found and the fault will be fixed.
