SPARK 2000 / 6000

thumb_Produkt-Spark6030-768x768At the extrusion of wires and cables, their insulation is inspected by spark testers (high voltage spark testers) and possible insulation faults are detected and documented at an early stage. For the testing, the dry cable runs through the sturdy electrode of the spark tester where the cable insulation is exposed to the selected test voltage and faults in the insulation are reliably detected.

According to the various applications, SIKORA offers Direct Current (DC), High-Frequency (HF) and Alternating Current (AC) spark testers.
