DC Spark Tester
ST-10D DC (Direct Current) Spark Tester Insulation Detector Of Cable is a recommended tool for detection cable surface defect and for spark test for wire and cable, the diameter of cable will be detected reach up to 10mm. The DC high voltage tester with steady voltage output, high sensitivity, adaptability, easy to us, and high reliability, it can be used for on-line testing, and combination with a pair twister, also used for extruder production monitor, intermediate detection and finished products detection.
Direct Current (DC) spark tester Insulation Detector are regularly specified in test standards for telecommunications cables, because DC generates almost no corona and no heat, it is a gentler test and can be used to test delicate insulation with weak dielectric properties. It is also recommended for wires with foamed dielectric.
