In-line high voltage fault testing systems

Spark Tester
High voltage detection of faults in the insulation or sheathing layers of electric cables

In-line fault testing on single wires and cables during the extrusion or rewinding process has become standard procedure today. ZUMBACH Spark Testers can be used to test the most diverse range of cable products as per international standards, like IEC 62230, UL 1581, UL 2556 and other. Integrated ports allow communication for easy integration with quality control systems (e.g. USYS). According to various applications, ZUMBACH offers Mains Frequency, Direct Current and High-Frequency spark testers. Typically they are installed at the end of the cooling trough in extrusion lines or in rewinding processes and detect the smallest defects and bare patches in the insulation or sheathing of electrical wires and cables.
